How to restore Windows if there are no restore points? Recovering Windows 7 without reinstalling.

I would divide the system recovery methods into the following:
1 Using Last Known Known Configuration
2 Using the "System Restore" mechanism normally
3 Using the system recovery mechanism not normally (via safe mode or the original Windows 7 installation disk)
4 Using a previously created system backup.

1) Suppose you encountered a problem with Windows 7 and wanted to restore the system, the simplest thing you can do is boot into Safe Mode and load the last known good configuration, to do this, press the key when loading the operating system "F8" and select "Last Known Good Configuration", press "Enter".

Last Known Known Configuration is a recovery option designed to boot your computer using the last known working system settings. Booting in Last Known Known Configuration mode restores the system registry information and driver settings that were used the last time the system successfully booted. Use Last Known Good Configuration mode if Windows 7 cannot boot normally due to incorrect changes.

2) If the first method is not suitable or did not help, you can restore the Windows 7 system using the " System Restore“The principle of operation of this recovery method is quite simple; recovery occurs thanks to the created recovery points. A restore point captures the state of the system at a specific point in time. Restore points are created automatically by the system, but they can also be created manually (this is the subject of this article). There are several ways to run System Restore - The first method is to click "Start" and write in the search bar "System Restore", a menu will appear at the top "System Restore" click on it with the mouse. The second way is to go along the path “Start-Control Panel-Recovery-Run System Restore”. A window will open "System Restore", press "Further", you will see all possible restore points to which you can return/“roll back” if you click on the button "Search for affected programs", you can see which programs will be affected by system recovery (I recommend choosing recovery two or three days before the system problem). Having selected the date, click "Further".

Confirm the restore point by clicking "Ready"

Then a message will appear stating that System Restore cannot be interrupted, click "Yes", after which the process of restoring and rebooting the system will begin.

After the reboot, if the recovery is successful, a window will appear.

3) If you have suffered from a virus and you do not have the opportunity to start system recovery using the above method, then you can “roll back” the system using Safe Mode or using a disk with the operating system:

We go into safe mode (by pressing "F8" at the very beginning of system boot) and select "Troubleshooting your computer", a window will open

- We insert the original installation disk with the operating system (it must match yours), boot from this disk (to do this, in the BIOS we change the boot from hard drive to boot from CD/DWD). Select the language, then in the window "Windows Installation", choose "Recoverysystems".

After this a window will open "Windows 7 System Recovery Options."

So, no matter which method you used, the result is the same - you have a window in front of you "Windows 7 System Recovery Options",

I propose to analyze a little the capabilities of this window.

Startup recovery- analysis of faults that interfere with the normal loading of Windows 7 and their further correction for normal loading and functioning of the operating system.

System Restore- that’s why this article was written, with the help of this function we can use a restore point to return the system to a more early period a time when there were no problems.

Restoring a system image- this tool allows you to restore the system from a backup. This method is described in more detail in recovery method 4.

Windows Memory Diagnostics- checks system memory for errors.

Command line- allows you to load the command line and with it you can delete files that interfere with loading Windows 7.

Click on "System Restore", after which a window appears stating that "rollback" system can fix problems... click « Further", select the required restore point.

After this, we agree with everything proposed, including rebooting, and as a result of all these actions, when loading Windows 7, we see a window

4) Restore using a previously made backup; creating a backup is described in more detail in the article. Connect the USB backup storage device, press "Start" - "Control Panel" - "Recovery". If the system does not start and there is no way to boot the system, you must follow the third point of the article, just select Restoring the system image.

In the window that opens, select " Advanced recovery methods".

Then a window will appear asking you to reboot the system, click " Restart".

After restarting, you must specify system recovery settings. I recommend leaving everything as default and just clicking " Further".

In the next step, the system itself will find the system archive.

Next, you can specify additional parameters.

After that, confirm your choice and press " Ready".

Confirm system recovery by clicking " Yes".

If all of the above methods did not help you, then all that remains is to return the Windows system to factory settings, i.e. lose all your data and programs. Let me say right away that this method is suitable if you have hidden volume recovery on the hard drive, it must be provided from the factory. You can see it if you right-click on the shortcut "Computer" and choose « Management- Management disks"

Below are the hotkeys for restoring laptops to factory settings:

• Acer- press the key combination Alt+F10
• Samsung- F4;
• Dell inspiron- when the dell.com splash screen appears, you need to type the key combination Ctrl+F11;
• HP Pavilion- when turning on, hold F11;
• Packard Bell- F10;
• Rover- when starting the laptop, hold down Alt;
• ASUS- when the ASUS logo appears, press F9;
• Sony vaio- at startup press F10;
• MSI- press F3 when starting;
• Fujitsu Siemens- after turning it on, press F8;
• LG- F11;
• Lenovo ThinkPad- F11;
• Toshiba- F8.

I hope this article has relieved you of your question. How to restore Windows 7 system and helped return your operating system to the point of stable operation.

It's no secret that sooner or later every computer user is faced with the task of reinstalling the operating system. There are many reasons for this, from unsuccessful installation or removal of a program to the consequences of exposure to viruses. Installing operating systems, drivers and programs necessary for everyday work is by no means a fun and lengthy task. Therefore, if the damage to the system is not fatal, experienced users choose to restore Windows without a complete reinstallation.

There are several recovery options. Let's look at the most basic and effective methods that will help in this matter.

Method 1. How to restore Windows 7 using standard OS tools.

First of all, you need to use the simplest and fastest option. To do this, boot into “Safe Mode”.
We start the computer. After loading the BIOS and displaying the main information of the motherboard, you must press the “F8” key.
As a result you will see the following

The list will contain a number in various ways OS loading. Select the “Safe Mode” item.

note. If the system manages to boot, the screen resolution will be 800 by 600 pixels, because The drivers work in VGA mode, this is normal.

The system will provide us with a choice of “Restore Points”. Intuitively select the date on which the system worked properly. To do this, switch the marker to the “Select another recovery point” option and click “Next”.

If there are no recovery points, then this option is not suitable for us, since the creation of Control Points was previously disabled. We forget about this method and move on to method No. 2.

Attention. To prevent such situations from occurring, do not disable the “System Restore” option.

Method 2. How to restore Windows without a “Restore Point”.

We were able to boot the system, but there is no restore point created earlier. In this case, you will have to use a disk with a Windows 7 distribution kit. It is worth noting that the distribution kit, that is, the assembly, must be the same as what is currently installed on the computer. How to create such a disk, read this article.

Take the Windows 7 disc and insert it into the drive. Click “Cancel” on the autorun window.

Enter the command “sfc /scannow” there

Click “Ok” and wait. As a result of this process, all missing or damaged files will be restored. All of them will be replaced with new and workable files from the optical disk.

If you want to learn more about the “sfc” command, then open the Run window and enter the “cmd” command there

As a result, we will see the following

Enter “sfc /?” and read the help

Attention. If for some reason the screen does not display readable text(hieroglyphs), then you need to change the font in the command line settings. Right click on the top of the window

Then click on “Properties” and experiment with fonts there.

A method for restoring Windows 7 without using Safe Mode will be discussed.

I would divide the system recovery methods into the following:

I hope this article has relieved you of your question. How to restore Windows 7 system and helped return your operating system to the point of stable operation.

Unstable problem windows work 7 is often associated with corruption or deletion of system files, for example, after reinstalling or installing an infected program. This is not the most difficult problem - there are many ways to restore data using standard OS tools or manually. The simplest and effective options Let's look at it further.

Rollback to last stable state

By default, in all Windows, protection is active for system partitions. It is responsible for creating special checkpoints containing configuration information and system files of the environment before modifying it - installing applications, drivers and updates. Moreover, restore points are created without such a reason by the system at a certain frequency or by the user himself.

If problems began to appear relatively recently, and you remember the approximate date of their appearance, then the best solution is to roll back the OS to the moment when no failures were observed during the operation of the OS.

In a production environment this is very easy to do:

All that remains is to reboot, after which the damaged system files will be replaced with previous working versions.

If windows won't boot

Even if the damage to system data is so serious that the OS cannot boot on its own, you can use restore points:

The corresponding selection utility will launch control point, which needs to be worked with in the manner described earlier.

If pressing F8 does not open the boot options window, you will only be able to get into the recovery environment if you use the boot/installation disk.

Using the standard SFC utility

This application checks and repairs basic OS system files. It can also be run on the command line with boot disk, from the window for selecting boot options after pressing F8 and from a running system. The last option is the simplest:

Once the operation is complete, SFC will notify you of the results - the corrupted data should be detected and corrected.

Recovering data manually

Sometimes the methods described above cannot fix the problem. For example, when updating DirectX from distributions that come with various applications, DLLs are often lost. Therefore, always try to update DirectX from the office. Microsoft website, and if trouble has already happened, then if there is new version all DLLs will be updated automatically after installing a fresh component package from the website http://www.microsoft.com/ru-ru/download/confirmation.aspx?id=35.

If there is no new version on the specified page, then any DLL from another source can be transferred to your system yourself. Libraries are stored in the following directories:

• for windows 7×32 - in the folder C:\windows\System32;
• for windows 7x64 - in the C:\windows\SysWOW64 directory.

If, when you launch an application, a window appears informing you that a DLL is missing, and the installer from the Microsoft website reports that you have the latest version of the libraries on your system and does not update the components, then you can simply use the search engine. Find DLLs on the Internet and move them to the specified folders.

Not only DLLs, but also any damaged system files can be extracted from the Windows 7 installation distribution. To do this, you just need to know which files are damaged. Often the OS itself informs the user about the absence of a DLL or about an application error, for example, Explorer.exe. You can get the information yourself.

Let's find out what system information is faulty

To do this, you will again need the command line; we have already described how to open it. Write the following command here:

indstr /N:"" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt", where N is the drive letter.

Press Enter, after which sfcdetails.txt will be created on the desktop, which you need to open and carefully review. Its content will be similar to the image below.

Here we see that the Accessibility.dll library is damaged. It is this that you will need to find on the Internet or extract it yourself from the existing Windows 7 distribution to carry out the recovery.

Extracting OS components from the distribution

In addition to the installation disk, you will need a small free 7-zip application. With its help, we will work with the install.wim image located in the sources directory. The order is as follows:

All that remains is to copy them to the desired folder or flash drive. You can replace damaged data with them using installation/bootable media or LiveCD.

Replacing damaged files with new ones

To load the environment, we will use the same installation drive from which we took the data we needed:

These steps allow you to get into a fully functional explorer. Here you first need to specify that the program displays all file types. This is done below in the drop-down list. Next, all that remains is to transfer the copied files from the flash drive or from another folder to the place of the damaged ones and reboot. In this way, without reinstallation, you can fix problems caused by damaged system data.

How to restore windows 7 without reinstalling

All owners of desktop computers or laptops, sooner or later have to reinstall the OS, be it Windows 7 or any other modification. There are many reasons for damage to the operating system (malware infection, incorrect installation of drivers, accidental deletion of system data, etc.). However, if information that is important to you is saved in the system partition of the PC (for example, on the desktop), after the demolition of the operating system it will also be deleted. To prevent this, instead of reinstalling, you can perform a Windows restore.

Ways to restore Windows 7 without reinstalling

The developers of this operating system took care of its reliability, equipping the product with many protective functions, among which the most useful is the recovery procedure. This software tool allows you to restore the functionality of the OS without completely reinstalling it.

There are several ways to initialize the Windows reanimation process:

• using last known known configuration;
• using the Chkdsk program;
• via a restore point;
• via BISO.

To complete the task you do not have to look for any software or use additional devices.

The only thing you need to prepare is a DVD with Windows 7 OS of the exact build that was installed on your computer. The ideal option is to use the same disk.

Restoring the last good configuration

Every time you exit the system, all the important data necessary for the launch and operation of the operating system is entered into the registry. It is this information that the recovery procedure uses.

To activate it you need:

1. Remove all additional storage devices from the computer (CDs, DVDs, flash drives, memory cards, floppy disks), and then restart it.
2. During windows loading hold down the F8 key. This will take you to the Additional Download Methods window.
3. Select Last Known Good Configuration.

If the system boots after completing the above steps, it is recommended that you important information, saved in the system partition (“My Documents”, drive C, desktop), copy it to another drive. After this, check your PC for malware and, if possible, perform a full system diagnostic.

Using this recovery procedure, you will not be able to recover lost personal data (music, videos, etc.), since it only works with system files. To restore such information, you need to use additional programs.

Restoring Windows using the Chkdsk application

Chkdsk (from the English “check disk”) is a program built into the operating system that searches for damaged system files on the hard drive and restores them.

One more useful property This tool is to diagnose storage media for mechanical damage to sectors and close access to them, thereby speeding up the operation of the system.

There are two ways to initialize Chkdsk:

• via graphical interface;
• from the command line.

In the first case it is necessary:

To run Chkdsk from the command line:

After this, the Windows system will be restarted and diagnosed for damage.

Applying a restore point

A restore point is an OS element that stores a copy of system files, drivers and installed programs recorded at a certain time. In Windows, such points are created automatically at regular intervals, as well as after installing and updating programs.

To use a restore point, you need to:

Restoring a Windows system via BIOS

If it is impossible to start the OS, restoring using the methods described above will not work. In this case, you can use the BIOS to resuscitate Windows without reinstalling it.

The procedure will be as follows:

All available methods for restoring a Windows system do not provide a complete guarantee of a successful outcome. Therefore, if one method does not work, you need to use another.

Recovering deleted or corrupted Windows XP and Windows 7 system files

There are times when you need to restore damaged or deleted Windows XP system files. System files have every chance of being deleted, corrupted, or replaced with infected files as a result, for example, of viruses. There are frequent cases of defective system files when the computer is turned off incorrectly (as an option, when the lights are turned off) due to errors in file system.

Below you will get the answer to the question: How to restore damaged system files without reinstalling the Operating System.

The method is suitable for cases where it is known which system files will need to be returned.

If the PC stops booting after an incorrect shutdown (power outage, turning off with a button, unplugging the power cord from the outlet), you first need to check the hard drive for logical errors.

The recovery process involves copying from the installation windows disk XP required system files. The windows distribution contains all the system files. They are located in the I386 folder. All the necessary files on the installation disk are written in compressed form and have an extension of the form .dl_ .ex_, etc.. I.e. the last character is replaced with an underscore.

We will need to unpack the files removed from the system from the windows installation disk into the folder where they should be present. If you do not have a windows distribution, you can download the archive with the I386 folder for 32-bit windows versions XP.

To return system files you need to boot from a bootable CD, for example ERD Commander. You can download the disk image here. You can burn a disk image using free program ISO Burner (you can download it from this link)

Let's look at how to unpack system files from a Windows installation disk using the example of restoring the file C:\windows\System32\userinit.exe, which is often replaced with banners blocking Windows. The process of restoring damaged system files from the installation disk is not fundamentally different for other files. The main thing is to know in which folder this or that file is located.

Boot from the ERD Commander disk. Select download ERD Commander 5.0 for windows XP. In the window that appears at the end of the download, select the path to the installed Windows OS and click OK.

Open My Computer. Insert the windows installation CD. From the I386 folder, copy the required system files with the extension dl_ or ex_ to the folder where they should be present in the installed system. For us, this is the USERINIT.EX_ file. Copy USERINIT.EX_ from the I386 folder to the C:\windows\System32\ folder. To achieve the desired result, right-click on the USERINIT.EX_ file and select Copy to from the context menu.

In the window that appears, select the path C:\windows\System32 and click OK.

After the file is copied to the system folder, you will need to unpack it. Unpacking system files with the dl_ or ex_ extension from the windows installation disk is done using the expand command. The command syntax is: expand [source file] [target file] To execute the command, you will need to launch the Command Prompt. From the Start menu, select Run. In the window that appears, enter the cmd command and press Enter.

In the command line window, enter the command to unpack our file: expand c:\windows\system32\userinit.ex_ c:\windows\system32\userinit.exe and press Enter.

Unpacking will be completed, as indicated by the text: “c:\windows\system32\userinit.ex_: 11863 bytes expanded to 26624 bytes”. System file recovery was successful. Now you can restart your PC.

Any other windows system file can be restored in the same way.

How to restore corrupted Windows 7 system files without reinstalling the system.

Now let's look at how to restore system files in Windows 7.

We boot from the "ERD-Commander" disk (in the menu on the disk when loading, you need to select the version for Windows 7) Download the disk image here.

In the network settings window, select “Skip” and confirm the reassignment of disks. Next, select the path to the windows system folder.

Launch the MSDaRT recovery tools.

Select "System File Checker" from the menu

Select the item “Scan and request before fixing” - click “Next”

As a result, the process of searching for damaged or deleted system systems will begin. windows files 7. It can last about 5 minutes. When the process is completed, a list of damaged or deleted windows files will appear. We tick the files that we want to restore and click “Next”.

The process of restoring Windows 7 system files will begin, after which the recovery results window will appear. Click "Next" and in the next window - "Done".

Keep in mind!

You need to be careful when selecting files for recovery, especially when using a pirated version or a Windows build.

Perhaps certain system files will be changed in it so that Windows does not ask for activation. The recovery tool may consider these files corrupted and replace them with the original ones, which is why Windows may display a message during its boot process about an unlicensed version of your Operating System. In case of restoring system files after removing the banner, select files to restore from the table below.

Windows system files and the folders in which they should be located:

Here are certain Windows system files, as well as the folders in which they should be located. By the way, if you find a certain file, but in a different folder, most likely it is a virus! (except for the c:\windows\system32\dllcache folder).

File	Folder
explorer.exe	c:\windows
iexplorer.exe	c:\windows
regedit.exe	c:\windows
notepad.exe	c:\windows
userinit.exe	c:\windows\system32
taskmgr.exe	c:\windows\system32

How to restore Windows 7/8/8.1 system files

Hello, friends! Recovering Windows 7 or Windows 8/8.1 system files most interesting topic. Especially if the operating system starts to fail, but we don’t have a recovery image and we forgot to turn on system protection so that recovery points can be created. In this case, we will not be able to restore the system from the image, we will not be able to roll back windows to the created restore point, and we are also too lazy to reinstall the system, since this will take the whole day. And right here we have another chance to return Windows to normal - try to restore system files. In this article I will try to fully cover the topic so that we can revive our computer in any situation.

Recovering system files on a busy system

If our computer somehow turns on, then we do the following (if it doesn’t turn on, see section 2 of this article).

Open the Start menu. In the search field we write “Com”. On the “Command Prompt” element, right-click and select “Run as administrator”.

In the command line that opens, write:

We are waiting a little...

If your system is fine, you will see the following image.

If your windows was broken, you will see the following.

System files were successfully restored. We reboot and immediately turn on system protection to create restore points so that next time we can simply roll back the state of the computer to a couple of days ago and that’s it.

It happens that when scanning the system, the sfc.exe utility found damaged files, but could not fix them. In this case, I would restore system files in Safe Mode. If in safe mode the same read the last paragraph 4 of this article.

If your computer does not boot at all, as discussed at the very beginning of the article, then read the next paragraph.

Recovering system files in the recovery environment

If our computer does not want to boot at all, then we use the recovery environment. You can load into it:

1. Pressing F8 several times when turning on the computer
2. Booting from a boot (installation) disk or flash drive

The first option will work if we have a boot partition that the system created when partitioning the disk when we installed the system. Boot partition size:

• windows 7 - 100 MB.
• windows 8 - 350 MB.

In any case, try pressing F8 several times during boot. A window should appear with additional download options. Select Troubleshoot computer problems.

In the next window, select the keyboard input method. Select the language in which your administrator password is set (if there is no password, you can immediately click Next >).

Select a user with administrative rights and enter a password if you have one. If there is no password, just click OK.

Select the command line.

If you are unable to enter the recovery environment using the F8 key, you will need to boot from the installation (bootable) flash drive or disk. How to boot from a flash drive - here. You can boot from disk in the same way. Only in this case you need to put the DVD-RW (optical disc reader) first in the boot priority.

I like to boot from removable media using boot menu. In maternal ASUS boards it is usually also called by the F8 key.

After booting from a flash drive or disk, I saw the following picture. I choose windows Setup - Installing windows.

Select System Restore.

We wait until all installed windows are found.

We choose the one that does not turn on for us. And here CAREFULLY! We remember the letter that the recovery environment assigned to your system (in the Folder column). I have this D.

Select Command Line.

Enter the command:

sfc /scannow /offbootdir=D:\ /offwindir=D:\windows

Instead of D, you substitute your letter. Press Enter and wait for the scan to complete

The virtual machine from which the screenshot above was taken had a blue screen, so I was not surprised that system files were found and restored.

How to find out the drive letter with windows installed

If you were able to use the F8 key to open the “Advanced boot options” window and select “Troubleshoot computer problems,” then we need to find out the drive letter where Windows is installed, which was assigned by the recovery environment. This can be done in two ways

1. Call the notepad with the command

In Notepad, open the File menu and select Open...

On the left, click Computer and in front of you will be disks with letters.

You can go to the disk and make sure what and where.

2. Use the DISKPART utility

On the command line enter:

diskpart - call the utility for working with disks.

list disk - view the list of disks.

select disk - select the hard drive I need.

detail disk - call up information about this disk.

For windows 8/8.1

If the sfc utility was unable to restore damaged system files, then you need to try to restore the storage of these system files. The place where copies of working system files should be located. As I understand it, it is located at C:\windows\WinSxS. That is, we must first fix the file storage, and then use the “SFC / Scannow” command to restore the windows system files.

Restoring storage using windows update

1. Launch windows PowerShell with administrator rights. To do this, open the Start menu or home screen and click on the “Search” icon. In the search box we write “PowerShell”. Right-click on “Windows PowerShell” and select “Run as administrator” or “Run as administrator”.

2. In the window that opens, write

Dism /Online /Cleanup-Image /RestoreHealth

and wait. If the storage is intact or it was restored using Windows Update, you will see the following picture.

If Image Health State: Healthy - everything is fine. Reboot the computer and try SFC /SCANNOW again.

Restoring storage using an image

If we have problems with Windows Update, then this method will do.

1. Download the original windows image 8/8.1 is the same bit size as your system. How to find out the bit capacity of the installed system - here.

2. Connect or mount the downloaded image. Right-click on the image and select “Connect” or “Mount”.

3. In the command line with administrator rights, we look at what editions there are in the image with the command

Dism /Get-WimInfo /WimFile:F:\sources\install.wim

I have 2 editions in my image. It’s hard to understand which one I need based on these distinctive signs. Let's use the first one. If it doesn’t work, the second one.

4. Launch Windows PowerShell with administrator rights and set the command

Repair-windowsImage -Online -RestoreHealth -Source F:\sources\install.wim:1

where F is the drive letter to which we connected the image, 1 is the Windows edition number in the image.

Recovering system files manually

If using the sfc utility it was not possible to recover damaged files, you need to try to do it manually. In this case, you need to additionally run the command

findstr /c:"" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"

Findstr/c: ""%Windir%\Logs\CBS\cbs.log>sfcdetails.txt

and carefully examine the sfcdetails.txt file on your desktop or in %windir%\Logs\CBS\.

It should be something similar to the picture below.

After the name of the damaged file is known (Accessibility.dll), we look for it on another computer with the same system as yours. If this is not an option, then I would download the original windows image and install it on the virtual machine. I found the file I needed and copied it to a bootable or installation flash drive. Then, from this installation flash drive, I booted into the recovery environment and launched the command line. From the command line I would open notepad. I opened the menu File > Open - and now I have an almost full-fledged explorer. We copy and replace the working file from the flash drive, reboot and everything should work.

If the option of installing a virtual machine does not suit you, then you can include the install.wim file in the folder. Then go to this folder and copy the necessary files.

1. Create a folder. For example, “Win8.1Pro” in the root of drive D.

2. Copy the install.wim file to the root of drive D.

3. Mount the install.wim file into the created folder.

Dism /Mount-Wim /Index:1 /WimFile:D:\install.wim /MountDir:D:\Win8.1Pro

Go to the created folder and copy the necessary files.

Disable the image

Dism /Unmount-Wim /MountDir:D:\Win8.1Pro /Discard

Conclusion

This is how I will try to restore system files in Windows 7/8/8.1. Write questions and suggestions in the comments. Thank you for sharing the article on in social networks. All the best!

How to restore system files in Windows 7

What to do when for some reason system files have sunk into oblivion and the computer cannot work normally? There is no need to worry, as the situation can be corrected.

Reasons for disappearing system files

It often happens that Windows system files disappear. Their absence interferes with the normal operation of the system or, even worse, prevents Windows from starting. The reasons for this may be different:

• the system file was deleted by a virus or blocked by an antivirus;
• accidentally, due to the fault of the computer user himself;
• due to Windows updates (if updates occur constantly over a long time, they begin to block each other).

Of course, you can go to extreme measures and reinstall the system. But this is not a solution if there are working documents saved on the desktop or folders on the system drive that cannot be lost, because after reinstallation they will definitely disappear. Before doing this, you should still try to restore system files for Windows 7.

How viruses work

It often happens that a virus got on the computer, after which the system file became damaged and was deleted. In this case, you need to look at the antivirus logs. It will indicate how the file was deleted, when and what virus it was infected with.

Sometimes it happens that the antivirus itself blocks important data after updating the OS. In this case, you need to go to the "Quarantine" section of the antivirus and find the missing files, then restore them and add them to White list or change your antivirus program.

Recuva

On Windows 7, system file recovery can be performed by a third-party program, for example, Recuva. It is completely free and easy to use even for those who will be doing it for the first time. Download it and install it. Having launched it, the first thing you need to do is go to advanced mode (the button on the top right), and then select the directory to scan ( windows folder) and start scanning.

After the system file check is completed, files with multi-colored circles next to them will appear (green - excellent condition, yellow - damaged, red - cannot be recovered). If the check shows that the desired object is in excellent condition, you can easily restore it by selecting the checkbox and clicking on “Restore”.

Let's rollback

A rollback restores the operating system using a checkpoint that was created before the error occurred. The operating algorithm is as follows: Start / All Programs / Accessories / System Tools / System Restore. Select an OS restore point that was created before the loss of important data. We launch a rollback, after which the Windows system files and folders will be restored. However installed programs will be deleted afterwards. You can view the estimated losses by clicking on the “Search for affected programs” button.

Troubleshooting

If it is impossible to restore system files on Windows 7 using a third-party program and a rollback cannot be done, you need to scan your computer for damaged and missing data. The command line will help in this matter.

Open it as an administrator. You can do this in several ways:

1. Start / All Programs / Accessories, right mouse button on cmd (command line) - “Run as administrator”.
2. Go to the system drive, windows folder, System32, right mouse button on cmd - “Run as administrator”.
3. In the Start search, enter cmd and press Shift+Ctrl+Enter.

In the window that appears, write sfc /scannow, after which the Windows 7 system files will be checked for integrity and restored if some of them malfunction.

After recovery, you need to make a point to restore the OS so that next time you can rollback it, rather than restore individual data. The algorithm is as follows: open the “Properties” section in “My Computer”, on the right side select the “System Protection” section. In the “Protection Settings” section on the system drive, protection must be enabled. If this is not the case, select it, click “Configure” and put a dot next to “Restore system settings and previous versions of files”. We choose a place for disk space (1.5-2 GB is enough). Click OK. Next, click “Create” and give it a name.

Now you can restore system files on Windows 7.

Windows 7 won't boot, system file recovery

While loading the OS, you need to constantly press F8 until the list and the words “Last Known Good Configuration” appear. Click on it, after which the system should start from the moment when Windows successfully booted up the last time. If that doesn’t work, select “Troubleshoot computer problems.” In the list, click on “Startup Repair”. Windows 7 system files will begin checking for errors and faulty data, after which we restore them by clicking “Fix and restart”.

Also, if a restore point was previously created, you can return the OS to its previous state using a rollback.

Boot disk

If the operating system does not boot due to data loss, you can return it to normal using a boot disk or flash drive. We insert the disk or flash drive into the computer and reboot it. Next, the bootable media needs to be set to first place as a priority. You can do it like this:

1. In BIOS settings. Go to the BIOS (F2, F11 or del key) and look for Boot Manager. There we set the flash drive or disk drive to first place as a priority. If the flash drive is not displayed, you need to activate USB support in the settings. These settings look different for each BIOS version.
2. Before starting the OS, press the boot menu key (F8, F11 or F12), after which Boot Manager will appear with a list of drives, from which we select the one we need. If bootable Windows is on a flash drive and it is not displayed, you need to activate USB support in the BIOS settings.

If the desired drive is selected, the installation of Windows 7 will start. After selecting the language, click “Next”, and then select “System Restore” at the bottom left side. In the window that appears, select “Startup Repair” or “System Restore”. The next steps are already familiar.

How to restore Windows without reinstalling

In operating rooms Windows systems XP, Vista and Windows 7 have a great feature - system restore. In fact, this function has some “time machine” capabilities, or so it may seem when you first use it.

When can System Restore help? Real example from practice.

Imagine the situation that you install a program that emulates virtual disk, for example, Daemon Tools or Alcohol 120%. Anyone who likes to play games is certainly familiar with these programs.

And then, after installation, you see that the virtual disk is not only not created, but also the icon of the real DVD drive that is installed in the system has disappeared. Uninstalling the program does not help, rebooting is also ineffective, nothing works. The system “does not see” the DVD drive! What to do and what to do? Is it possible to fix the problem with little effort, without reinstalling Windows? Can. You need to use the system restore function.

The system restore function seems to take the system back in time and restore it to the way it was before the installation of the ill-fated program, which caused a failure - the DVD drive disappeared.

The essence of recovery is that before installing new programs or at a certain time, the system saves the so-called restore point. A restore point creates a snapshot of the system, saves registry data, basic system parameters, drivers, etc.

When a failure occurs, you can use this restore point and roll back the system to its previous, working state.

What does it look like? If you have the recovery function enabled on your computer, the system automatically writes to HDD"restore points". Let's see what this looks like with an example.

Press the button " Start", then select " All programs" - "Standard" - "Service" and we see the item "". Select it. A window appears in which a brief description of the recovery function appears. It is worth noting that the recovery function cannot restore deleted programs. We are directly told about this in the first window: " Recently installed programs and drivers may be removed".

The reason for creation may be the installation of a program, components Windows updates, driver installation, scheduled restore point.

As you can see in the screenshot there are 3 recovery points. All of them were automatically created before installing Windows 7 OS updates. The number of restore points depends on the amount of memory that is reserved for data storage. If the reserved space on the hard drive is not enough to create a new point, then the oldest recovery point is deleted and a new one takes its place.

If there are few recovery points in the list, you can check the "" checkbox. In this case, the number of points may increase. Take a look.

Which restore point should I choose?

It is recommended to select the closest restore point, the creation date of which precedes the occurrence of a failure or incorrect operation of the system. Thus, we restore the system before the failure occurred. If I select a restore point from the list shown in the screenshot above, then I would select the first or second line from the top ( 18.05.2013 And 16.05.2013 dates). So, we select, click next. A final window appears in which we will be asked to confirm our choice.

After we press the button " Ready"The recovery process will begin, which may take some time (always different). Usually this process takes no more than 15 - 20 minutes, but there may be exceptions, so plan in advance to spend about half an hour on this.

During recovery, a progress bar will be displayed on the computer screen, which can be used to monitor the process. Once the recovery is complete, the computer will restart and a message box will appear on the screen indicating that the recovery is complete or incomplete. Yes, this happens too. But this is rare. If this happens, then you should think about a general system check or reinstalling Windows (a last resort).

Before starting the recovery process, it is a good idea to find out which programs will be affected during recovery. This means that program files that will be affected by the restore may be deleted. Naturally, after this the programs will not work, only folders with some files that were created when installing the program itself will remain. You can find out which programs will be affected by clicking the link " Find affected programs". A new window will open and the scanning process will begin.

After a few seconds, a new window will open containing a list of programs and components that will be affected by the recovery.

In this case, no affected programs were found because no third-party programs or drivers were installed after the selected restore point was created.

Is it possible to undo System Restore?

One of the nice features of the recovery feature is rollback recovery. That is, if the restoration was unsuccessful or did not fix the problem, it can be canceled. In this case, the reverse procedure will be performed. You can start undoing the recovery only after the recovery process has finished and the computer has restarted.

If recovery does not help, then you can roll back the recovery and select another restore point. Perhaps it will fix the problem. If the recovery fails, then the matter may be much more serious, and you will have to resort to reinstalling the Windows system.
