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.
