This article describes the System File Checker tool (Sfc.exe) that is used with the Windows File Protection (WFP) feature.
The System File Checker tool gives an administrator the ability to scan all of the protected files to verify their versions. The System File Checker tool also checks and repopulates the %SystemRoot%\System32\Dllcache folder. If the Dllcache folder becomes damaged or unusable, you can use either the sfc /scanonce or sfc /scanboot command to repair the contents of the folder.
