Windows provides you with a tool to scan your registry for any corruption or deleted entries. The tool is called “scanreg,” and it is run in the Windows command prompt. The software scans each key in the registry and attempts to fix any errors. If the hard disk is corrupted in the location where the Windows registry is saved, scanreg alerts you and moves the files to a safer location on the drive. This tool is simple to use and only requires a few steps. Writer Bio
