How Repair Corrupted Windows 10 System Files [Tutorial]
165If Windows is experiencing blue-screen or other crashes, applications are failing, or some Windows features just aren’t working properly, there are two system tools that might be able to help. The System File Checker (SFC) tool built into Windows will scan your Windows system files for corruption or any other changes. If a file has been modified, it will automatically replace that file with the correct version. If the SFC command doesn’t work, you can also try the Deployment Image Servicing and Management (DISM) command on Windows 10 or Windows 8 to repair the underlying Windows system image. On Windows 7 and earlier, Microsoft offers a downloadable “System Update Readiness Tool” instead. Let’s take a look at how to use them.
Run the SFC command when troubleshooting a buggy Windows system. SFC works by scanning for and replacing system files that are corrupt, missing, or changed. Even if the SFC command doesn’t repair any files, running it will at least confirm that no system files are corrupted and then you can continue to troubleshoot your system with other methods. You can use the SFC command as long as the computer itself will start. If Windows will start normally, you can run it from an administrative command prompt. If Windows won’t start normally, you can try starting it in Safe Mode or in the recovery environment by booting from your installation media or recovery disc.
