Windows File Protection “SFC /SCANNOW”

If your Windows files are corrupted/infected by any virus, the best way to restore them is by using Windows File Protection.
Open Start>Run>”cmd”>”sfc /scannow”
The windows file protection will start running.
It scans all protected system files and replaces incorrect versions with correct Microsoft versions.
It will ask you to insert your WindowsXP cd to replace the files.

* You can customize the drive for cd. Open Regedit and goto “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup”. Change “SourcePath” and “ServicePackSourcePath” to your drive letter.
