How to fix system scan error on Windows 8?

How to fix system scan error on Windows 8?


Open a command prompt with admin rights and run this DISM command to detect and repair corrupted files on the HDD:

DISM /Online /Cleanup-Image /RestoreHealth

This is the advanced version of sfc /scannow. Windows now downlaods the corrupted files from the Internet instead of telling you that the files can't be repaired.
