Situatie
A system file plays an important role in the operating system and when it gets damaged and cannot complete its function, it may be called corrupt. All the programs can end up having corrupted files but when these files are part of the operating system, things can get a little bit more complicated.
There are a lot of possible reasons for which your Windows files or system files can become corrupted, but here are the most common ones:
➡ Viruses and malware – Even though not as common as you might think, viruses and malware will sometimes cause system files to get corrupted. This occurrence is not very common as the main goal of a virus or malware is to gather important data, so crashing your system would not meet their end goal.

Use the SFC tool
- Type cmd in the Search box and click on Run as Administrator to open an elevated Command Prompt window.
- When Command Prompt opens, enter the following command and press Enter:
- sfc /scannow
- Don’t close Command Prompt or interrupt the repair process. It can take a while, so wait patiently while it completes.
Use the DISM tool
- Press the Windows key + X and click on Windows PowerShell (Admin) or Command Prompt (Admin) to open the app with administrative privileges.
- Type/paste the following command and press Enter:
- DISM /Online /Cleanup-Image /RestoreHealth
- The repair process can take 10 minutes or more, so be patient and don’t interrupt it.
- After DISM tool repairs your files, restart your PC.
Run a SFC scan from Safe Mode
- Press the Windows key to launch the Start menu, click on the Power button, and while holding the Shift key, select Restart.
- You’ll see three options available. Select Troubleshoot.
- Select Advanced options.
- Next, click Startup Settings.
- Click the Restart button.
- When your PC restarts, you’ll see a list of options. Select any version of Safe Mode by pressing the appropriate key.
When Safe Mode starts, repeat the steps from Solution 1 to perform an SFC scan.
Perform a SFC scan before Windows 10 starts
- Press the Power button to turn on the system, and as soon as the Windows logo appears, hold it to turn off the computer.
- Repeat the same process thrice, and on the fourth attempt, Windows will automatically perform a Startup repair.
- Once the process is complete, click on Advanced options.
- When the list of options appears, select Troubleshoot.
- Choose Advanced options and select Command Prompt.
- When your PC restarts, you might be asked to enter your username and password, so be sure to do that.
- Find the letter of your Windows 10 drive. To do that, enter the following command and press Enter:
- wmic logicaldisk get deviceid, volumename, description
- Pay attention to Volume Name. In most cases Windows Volume Name will be assigned to the letter D. This is perfectly normal if you start Command Prompt before starting Windows, so no need to worry about it.
- Also check System Reserved drive. In most cases, it should be C.
- Enter the following command and press Enter (Be sure to use the letters that you got from the previous steps):
- sfc /scannow /offbootdir=C:\ /offwindir=D:\Windows
- Wait while your system files are scanned.
- After the scan is completed, close Command Prompt and start Windows 10 normally.
