Please follow the instruction below to repair Windows 10 System Files:
You’ll need to do this from and Administrator Command Prompt window. To open one on Windows 10 or 8.1, right-click the Start button and select “Command Prompt (Admin)”. On all versions of Windows, you can also search the Start menu for Command Prompt, right-click it, and select Run as Administrator.
Leave the Command Prompt window open until the command completes — this may take some time. If everything is fine, you’ll see the message “Windows Resource Protection did not find any integrity violations.”
If you see a “Windows Resource Protection found corrupt files but was unable to fix some of them” message, try rebooting into Safe Mode first. On Windows 10, 8.1, or 8, hold the Shift key while clicking the Restart option to access the advanced boot options menu. On Windows 7 or earlier, reboot your computer, and then press and hold the F8 key while it’s booting up. Run the sfc /scannow command from within Safe Mode.
Run the DISM Command to Fix SFC Problems
On Windows 10, 8.1, and 8, the Deployment Image & Servicing Management tool can fix component store corruption that prevents the SFC command from working properly.
To run this command, open a Command Prompt as administrator. Type the following command and press Enter. DISM will check your Windows component store for corruption and automatically fix any problems it finds.
DISM /Online /Cleanup-Image /RestoreHealth
Allow the command to finish running before closing the Command Prompt window. This may take five to ten minutes. It’s normal for the progress bar to stay at 20 percent for a while, so don’t worry about that.
If the DISM command changed anything, restart your computer afterwards. You can now run the SFC command again and it would be able to replace any corrupted files with the correct ones.
