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 systems 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 messages or running erratic.

To use the System File Checker, follow these steps:

  1. Close any open programs on your Desktop
     
  2. Click on the Start button
     
  3. Click Run
     
  4. Type this command in the Run box: SFC /SCANNOW
     
  5. Click the "OK" button
