How to Repair Missing or Corrupted System Files in Windows 10/11

In today’s tutorial, I’m going to show you how to repair missing or corrupted system files in Windows.

*To get started:*
1. Go into the Windows start bar, and type in “Command Prompt”, and right click on the command prompt application, and select the “Run as administrator” option.
2. Please note, to run today’s command, you have to be running command prompt as an administrator.
3. Now type in the following command “sfc /scannow”, now hit the enter key on your keyboard.
3. A system scan will now begin, and it should take a few minutes to fully complete.
4. While we’re waiting, I’ll explain what this command is doing. The command is a Windows System File Checker Tool used to scan the integrity of system files and repair any corrupted or missing files found during the scan. When you run the command, Windows checks the integrity of all protected system files on your computer. These system files are crucial for the proper functioning of the Windows operating system.
5. If the System File Checker finds any corrupted or missing system files during the scan, it attempts to repair or replace them with the correct versions. It uses backup copies of the original system files stored in the Windows component store (WinSxS folder) or installation media.
6. By repairing corrupted or missing system files, the command helps maintain the stability and reliability of your Windows operating system. It can fix issues related to system crashes, startup problems, application errors, and other performance issues caused by corrupted system files.
7. After completing the scan and repair process, sfc /scannow provides feedback on the results of the scan, including details about repaired files, if any. You can review the scan results to determine the extent of file corruption and the effectiveness of the repair process.
8. In summary, the sfc /scannow command is a valuable troubleshooting tool for diagnosing and repairing corrupted or missing system files in Windows. It helps ensure the integrity and stability of your operating system by identifying and fixing issues that could potentially impact system performance and functionality.
9. Now that we’ve reached 100%, you can see that the scan went well, and no issues were found. If there were issues, they’d be listed here, and an explanation of how they were fixed would be provided.

And it’s as easy as that, repairing missing or corrupted system files in Windows is a fairly simple task to perform.

I’d like to note that at first this didn’t help me, but I was transferring an external hard drive OBS file from a laptop (original source of recording) to a desktop (Not original source of recording). When I used this method the first time, it was on the desktop (not the original source of recording). But when I plugged the external hard drive back into the original source of recording, which was my laptop, it worked. So thank you so much for this video.. P.S the ending is kinda sketch considering there weren’t examples of a corrupt file being fixed. But thank you, I’m going to be using this method for when I get more corrupt files!

Hey, please tell me what happens in my case when I start Windows 11 and when I create several files, copy something [no matter which disk - on each] and then switch to Windows 10, it turns out that my disks are damaged and the new ones are invisible files created for Windows 11 and after repairing in chkdsk, new files sometimes show up working and sometimes damaged, do these systems interfere with each other? I'm afraid I'll lose my data because many files disappear after such a repair. Help me because I have searched the entire Internet and found nothing, and in the opposite case - all files created for Windows 10 work under Windows 11

Hej napiszcie mi proszę co się dzieje w moim przypadku gdy uruchamiam Windows 11 i jak stworzę kilka plików coś skopiuję [ nie ważne na którym dysku - na każdym] i później przełączę się, na Windows 10 to okazuje się że mam uszkodzone dyski i niewidoczne te nowe pliki stworzone pod windows 11 i po naprawie w chkdsk nowe pliki czasem się pokazują działające a czasem uszkodzone, czy te systemy się gryzą? boję się że stracę dane bo wiele plików po takiej naprawie znika. Pomóżcie mi bo przeszukałem cały internet i nic nie znalazłem a w odwrotnym przypadku - wszystkie pliki stworzone na windows 10 działają pod windows 11
