How to Scan Windows & Fix Errorsby Craig Witt
Microsoft's Windows 7 and Windows Vista operating systems include a built-in utility that allows you to scan your computer and automatically fix file system errors. Performing this task can help you solve functionality problems and improve the performance of your hard drive without turning to third-party software or outside help. Once you understand how to access the utility and set the appropriate options, scanning Windows and fixing file system issues becomes a quick process.
Close all programs.
Click the Windows "Start" button and select "Computer."
Right-click the name of the drive you want to scan and select "Properties." By default, Windows resides on your "C:" drive.
Select the "Tools" tab located near the top of the resulting dialog box.
Click the "Check Now" button, located below the "Error-checking" heading. Confirm your choice if prompted by Windows.
Check only the box labeled "Automatically fix file system errors."
Click "Start." The scanning process begins immediately. It generally completes within 10 minutes.
