Scan Windows 7 system files to repair errors

First you will need to start a permission-elevated command-line prompt. Typecommand into the Desktop Search box and then right-click on the Command Prompt menu entry and select the Run as Administrator item (Figure A).

After accepting the elevated permissions, at the prompt type this command:

sfc /scannow

Now the system will verify the system

files and repair any corrupted files (Figure B).

My test system had no errors (Figure C); however if it did, this scan would have repaired any corrupted files, but without forcing a system reboot.
