Run SFC command to restore system files

Run an SFC command when troubleshooting a faulty Windows system. SFC finds and replaces damaged, missing or modified system files. Even if the SFC command does not repair any files, running it at least confirms that the system files are intact and you can continue troubleshooting using other methods. You can use the SFC command while the computer starts up by itself. If Windows starts normally, you can start it from the Administrative Command Prompt. If Windows does not start normally, you can try starting it in Safe Mode or in the environmentrecovery by booting from the installation media or recovery CD.

Regardless of how you access the command line – usually in safe mode or in the recovery environment – use the command the same way. Remember that when Windows starts normally, you need to open a command prompt with administrator rights. To do this, right-click the Start button and select Command Prompt (Admin).

At the command prompt, type the following command and press Enter to run a full system scan and try to repair the SFC:

 sfc / scannow 

Do not close the Command Prompt window until the command has run. This may take some time. If everything is in order, the message “Windows Resource Protection found no integrity violations” is displayed.

If the message “ResWindows found corrupted files, but could not recover them ”, restart your computer in safe mode and run the command again. If that doesn’t work, you can also try booting from the installation media or recovery CD and running the command from there.

Normally, you do not need to run the DISM command. However, when the SFC command does not work correctly or the corrupted file cannot be replaced with the correct file, sometimes DISM or the Windows 7 System Update Readiness tool can repair the system. Windows underlies and runs SFC correctly.

To run DISM command on Windows 8 and 10, open a Command Prompt with administrator rights. Type the following command and press Enter to have DISM scan the Windows Component Store for corruption and automatically fix any issues it finds.

Allow the command to run before closing the command prompt window. This can take five to ten minutes. Bandprogress stays at 20% for a while, that’s okay, so don’t worry about it.

If the results of the DISM command show that something has changed, restart your computer and then you should be able to run the SFC command successfully.

DISM command is not available in Windows 7 and earlier. Instead, you can download and run the Microsoft System Update Readiness Tool and use it to scan your system for problems and try to fix them.
