SFC /purgecache 

 

Purges the Windows File Protection file cache and scans all protected system files immediately.

To purge the cache do the following

  1. Open Command Prompt

  2. Type SFC /purgecache (There is a space between the SFC and the /)

   

  1. 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.
