Sfc/scannow (System file scan and Repair) command of experience

The premise of running this command is very, very important: The system installation disk, must be installed in the system you use the installation disk, into the optical drive.

Try one: Click "Start"--"run"--type "Sfc/scannow"--click "Enter". Blocked, display "Cannot find system files" and so on.

Try two: Click "Start"-"Run"-Enter "Sfc/scannow" (note that there is a space after the SFC)--click "Enter". The program starts and scans and repairs the system files.

Try three: Click "Start"--"Run"--enter "CMD"--click "Enter"--in the DOS window input "Sfc/scannow"--click "Enter". The program starts and scans and repairs the system files.

Try four: try three: Click "Start"--"Run"--enter "CMD"--click "Enter"--in the DOS window input "Sfc/scannow" (note this SFC after a space)--click "Enter". The program starts and scans and repairs the system files.

I have tried the above four kinds of situations, except the first one does not work, the remaining three kinds are feasible.

This command is indeed a very quiet command, which automatically fixes the system files in the background and does not require human intervention during the scanning process. To view the fix, open Control Panel--double-click Administrative Tools--double click event Viewer--double click on "System"--click "Date", sort it by the nearest time--right-click "info" to view "Properties" When you start the scan, and the details are at a glance.
