Win 7 Restore system files. Check and restore the integrity of system files Windows

Restoresystemic system windows files 7 Is it performed just like in Windows XP? The operating system I have a seven, installed for a long time, some time ago, messages began to appear that you need to restore system files and all that. I type in the SFC / SCANNOW window in the window, on some fraction of a second, the dark window flashes and on it, the system scanning does not occur. My friend when I did on my laptop the same thing and everything turned out.

Restore Windows 7 system files

Your question is very simple, this is happening because you have controls. accounts , pay attention to the symbol, see under your team sFC / SCANNOW. There is no inscription "This task will be completed with administrator rights",

that is why you can't run from here restore Windows 7 system files. You should turn off the UAC, then restarts and you can run the restore window in the window.

But I would not turn off the monitoring records, but would do something else, you need to press once the launch button-\u003e All programs-\u003e Standard, then visit the mouse command line and click on the right mouse, in the drop-down menu, select Run from Administrator name. And already on the command line for restore system files Score SFC / SCANNOW and ENTER. A system scanning should begin on the subject of violated or missing system files.

By the way, if problems started with you not long ago, you can take advantage of the system restoration and roll back for a while when your seven worked stably. Personally, I always keep in stock three

Windows? The integrity check of Windows 10/8/7 / XP is needed if they suspected that some of the system sections have changed or have been defects due to the impact of a malicious program.

There are several tools to check the integrity of Windows 10 files. The most common - SFC.exe, is often used by dism.exe. You can also use the REPAIR-WindowsImage function performed in PowerShell. We recommend to apply several ways, but alternately. This is necessary because each of the options will check the integrity of different files. If you needed such a procedure, however, you do not know how to check the integrity of Windows 10 system files correctly to adjust them, resume work, carefully read the recommendations below, follow the sequential steps, then you can check, restore the integrity of Windows 10 system files and other versions.

Check the status of system files using Windows

Scanning by SCF.

Many users to scan the operating system before restoring lost, damaged files performed for the purpose of their correct operation, resuming uninterrupted work, troubleshooting by restoring damaged components, use the SFC / ScanNow command, it is in offline mode Explores and corrects system sections of Windows 10.

• To activate this command, first open CMD, start to enable administrator. You can activate the utility using a mouse by right-clicking on the main menu "Start", then by selecting the "Command Line" list. In the dialog box, type SFC / SCANNOW, press ENTER.
• Check will be started, defects will be identified, then start corrected without your intervention, assistance automatically, the system itself. If the errors are not found, you will be reported that the protection of the OS resources is not detected.

• If you decide to check out some one, defined from system files, then in the command prompt, specify SCF / scanfile \u003d "path to the file".
• It should not be noted that the SCF is not able to correct the errors of those partitions that are run at the time of scanning, so it is best to operate SFC solely when starting "Restore wednesdays Windows 10".

Running SFC using recovery environment

To correctly activate SCF, follow the steps below the described algorithm.

After holding the above steps, a list of volumes will appear, you must remember or write down the letters that match system section And the disk "reserved by the system".

sFC / / SCANNOW / OFFBOOTDir \u003d Letter section of the bootloader: \\ / offwindir \u003d E: \\ Windows (or your path to the Windows 10 directory).

As a result, scanning must start, checking the integrity of system files, the recovery will be available for all of them. Note that checking will take a fairly significant amount of time, you do not need to turn off or restart the computer throughout the procedure. The last action will need to execute only when the scan is completed and you will close the command line.

Scanning via Dism.exe.

The specified utility is operated for mounting images, makes it possible to identify and correct the problems arising from the OS sections as a result of their damage, perform recovery. It is perfect for those partitions that SFC could not cope. You can also apply it if SFC could not detect any problems when scanning. Therefore, not limit yourself to only one type of scanning and treating damaged areas, be sure to run this operation when working with system components.

For launching Dism.exe also applies command line. Activate it from the administrator and follow the steps:

• dISM / Online / CleanUp-image / checkhealth - This feature provides information that are in stock defects, damage to various components of Windows 10. Deep check, however, not performed, only previously found data is used.
• dISM / Online / CleanUp-image / scanhealth - scanning for possible damage to the component storage. This check often requires enough time, periodically folling during the implementation process (usually by 20%).
• dISM / Online / CleanUp-image / RestoreHealth - careful inspection and recreation of system files offline, recovery, which also takes a long time.

All Action Logs In the execution of the commands described above, Windows \\ Logs \\ CBS \\ CBS.log, Windows \\ Logs \\ DISM \\ DISM.LOG

Like the previous utility, the DISM is also started by mode windows restoration 10.

Checking the integrity of system files in Windows 7/8 is identical to the same operation in the 10th. It is carried out similarly - through the command line via SFC and the corresponding command. All actions are performed in the same sequence as described earlier. By a similar algorithm, the integrity of system files in Windows XP is checked. The start of the command line interpreter is true:

• go to the "Start" menu;
• click on the "Run" option;
• in the dialog box, type the "CMD" command, then on the ENTER keyboard.

As a result, an ordinary command line will open, you can perform all actions to check the OS files for defects.

All specified operations will help restore damaged, damaged partitions. operating system Windows class, which will solve intervention problems malicious programs In the work of the computer, the speed will return to his work, will avoid extreme measures, such as full recovery Systems in troubleshooting. You do not need to reinstall fully OS, it is enough to restore damaged components. Remove them with the help of special teams and utilities, and your computer will continue its work.
