SFC /revert
			
Returns the scan to its default operation.
To return to the default operation, do the following
- 
				Open Command Prompt 
- 
				Type SFC /revert (There is a space between the SFC and the /) 
|  | 
- 
				Press Enter 
NOTES:
- 
				You must be logged on as member of the Administrators group to run sfc. 
- 
				If sfc discovers that a protected file has been overwritten, it retrieves the correct version of the file from %systemroot%system32\dllcache folder, and then replaces the incorrect file. 
- 
				If the %systemroot%\system32\dllcache folder becomes corrupt or unusable, use sfc /scannow, sfc /scanonce, or sfc /scanboot to repair the contents of the Dllcache directory.
