Method 7: Use the System File Checker (Sfc.exe) tool to scan all Windows File Protection (WFP)-protected files

Use System File Checker with the /scannow parameter to immediately scan and verify the versions of all the system files that Windows File Protection helps protect. If System File Checker discovers that such a file was overwritten, it retrieves the correct version of the file from the cache folder (Systemroot\System32\Dllcache) or from the Windows installation source files, and then replaces the incorrect file. System File Checker also checks and repopulates the cache folder. You must be logged on as an administrator or as a member of the Administrators group to run System File Checker.

To run System File Checker with the /scannow parameter, follow these steps:

1. Click Start, and then click Run.
2. In the Open box, type cmd, and then click OK.
3. At the command prompt, type sfc /scannow, and then press ENTER.
