Launch the System File Checker Program
Scanning and fixing Windows System files will improve the function and speed of your computer.
The Windows system consists of a group of program files that work together to run your computer. All activities, including applications (like word processors, email, Internet browsers), are controlled by these system program files. Over time, these files can be changed or corrupted by new software installations, viruses, hard drive and other problems. The more corrupt the system files are, the more unstable and problematic your Windows operating system will become. That is why scanning and fixing Windows system files is so important.
The SFC (System File Checker) program scans all protected system files and replaces corrupted or incorrect versions with correct Microsoft versions. This procedure can be very beneficial, especially if your computer has been displaying error messsages or running erratic.
1. To use the System File Checker, follow these steps:
2. Close any open programs on your Desktop
3. Click on the Start button
4. Click Run
5. Type this command in the Run box: SFC /SCANNOW
6. Click the "OK" button
Allow the SFC Program to Work
It may take from 30 minutes to a couple of hours to scan and fix all windows system files. It will work fastest if you do not use the computer during this process. You may continue to use the PC, but performance will be very slow.
1. Follow any instructions that the SFC program gives you
2. When the SFC program has finished, the Run window will close.
3. Once complete, you may resume your other activities.
