Vista has the ability to repair itself from 3rd party software overwriting important system files. To fix this we will use a utility called System File Checker or sfc for short Parameters /scannow : Scans all protected system files immediately. /scanonce : Scans all protected system files once. /scanboot : Scans all protected system files every time the computer is restarted. /revert : Returns the scan to its default operation. /purgecache : Purges the Windows File Protection file cache and scans all protected system files immediately. /cachesize=x : Sets the size, in MB, of the Windows File Protection file cache. /? : Displays help at the command prompt.
