Windows system files contain comprehensive instructions for running the operating system. If a corrupted file or file is deleted, you can use the “System File Checker” tool included in Windows Vista and Windows 7 to repair and replace the files. This tool allows you to save a copy of the file system to the system directory, solving any problems you may have had with the file.
Steps to follow:
1.Click on “Start”. Then, click on “All Programs,” then click on “Accessories.” Click on the “Command Prompt” and select “Run as administrator” from the pop-up menu. You must run the system as an administrator, since only one administrator can replace the system files in Windows.
2.Enter the administrator password in the dialog window. Click “Allow” to access the command line as an administrator.
3.Type “sfc / scannow” and press “Enter.” “SFC” is synonymous with “System File Checker”. The utility scans the entire system directory for damaged files and replaces the damaged files. This utility may take several minutes to complete.
