Windows 8.1 system integrity

Windows system has an integrated integrity checking tool that has been around for ages, called “sfc”. It can be used when you suspect that Windows system has been corrupted.

Using SFC

Click Start button and then down arrow to display all programs. Type “Command prompt” in the search field. Right click the Command Prompt icon and use “Run as administrator” control at the bottom of the screen. Into the command prompt, type in:

sfc /scannow

This will initiate the integrity checking feature which can take a while to check all the system files. In general, it should fix the corrupted files on its own. But from my experience, it seems to be broken very often on Windows 8.x systems by constantly saying it found corrupted files, but couldn’t fix them. In that case you have to use DISM tool.

Using DISM

Click Start button and then down arrow to display all programs. Type “Command prompt” in the search field. Right click the Command Prompt icon and use “Run as administrator” control at the bottom of the screen. Into the command prompt, type in:

Dism /Online /Cleanup-Image /RestoreHealth

This will initiate the re-evaluation of the system integrity system. Just like SFC, it can take a while to complete. After that, I recommend running SFC tool again. It should say there are no problems this time around.
