System File Checker for Windows

Hello

Some time we have problems with a windows installation. In those moments it is important some tools for this matters, the scandisk utility, fragmentation, antivirus, etc…
But one option very important must be the System File Checker, a tool for check and recover the system’s files.

Run.. -> cmd (run as administrator)

sfc /scannow #Scan right now

sfc /scanboot #Scan at boot

sfc /revert #Return to default operations

sfc /? #More information

I hope this will be use-full for someone as for me.
