SFC's use of parameters _ application techniques under WIN2000/XP

WIN2000 's sfc start-up method is very special, to enter the virtual DOS (run cmd) before you can enter SFC or parameters, otherwise it will not be able to run. The specific format of SFC is:


SFC [/scannow] [/scanonce] [/scanboot] [/cancel] [/enable] [/purgecache] [/cache size=x] [/quiet]


Each parameter means:

The parameters to be marked with bold are carefully used


/scannow immediately scans all protected system files
/scanonce scans all protected system files once
/scanboot scans all protected system files each time it starts
/cancel remove all paused protected system files from scanning
/enable enable Windows File Protection for normal operation
/purgecache clears the file cache and scans all protected system files immediately (only if you are sure that the system is free of problems, because once you use the system's cache will be all lost, it is more cumbersome to recover the system files)
/cachesize=x Unit: MB Set File cache size (based on hard disk space size)
/quiet does not prompt the user to replace all incorrect file versions (be sure to consider whether to use this parameter, because using incorrect system files can easily cause system paralysis)
