    System File Checker (SFC) - sfc/scannow

    An administrator has the ability to check the versions of all protected files using System File Checker. When System File Checker notices that a protected file has been rewritten, it searches the cache folder or the source files of the Windows installation for the right version of the file and replaces the corrupted one. The cache folder is examined and updated by System File Checker. To use System File Checker, you must be logged on as an administrator or a member of the Administrators group. The sfc /scannow, sfc /scannce, or sfc /scanboot commands can be used to restore the contents of the Caches folder if it becomes corrupted or useless.
