Repair system files in Windows 10

Repairing system files in Windows 10 can help resolve various issues and errors. Here's how you can do it using the built-in System File Checker (SFC) tool:

Open Command Prompt as Administrator:

Right-click on the Start button.

Select "Command Prompt (Admin)" or "Windows PowerShell (Admin)".

Run the System File Checker (SFC) tool:

In the Command Prompt or PowerShell window, type the following command and press Enter:

1. Wait for the scan to complete:

   • The scan may take some time, and the progress will be displayed in the Command Prompt window.

2. Review the scan results:

   • • "Windows Resource Protection did not find any integrity violations": No issues were found.
     • "Windows Resource Protection found corrupt files and successfully repaired them": The tool found and fixed issues.
     • "Windows Resource Protection found corrupt files but was unable to fix some of them": The tool found problems but couldn't fix them automatically.
     • Once the scan is complete, check the results. There are three possible outcomes:
     • If issues were found and fixed:
     • Restart your computer.
     • If issues were found but not fixed:
     • If the SFC tool couldn't fix some files, you may need to use the Deployment Image Service and Management Tool (DISM) to attempt additional repairs. In the same Command Prompt window, type the following command and press Enter:
     • 
       
     • Restart your computer:
     • After completing the above steps, restart your computer to apply any changes.
     • 
       
     • If you encounter difficulties or if the issues persist, you might want to consider more advanced troubleshooting steps or seek assistance from Microsoft support. Additionally, creating a system restore point before making changes is a good practice in case anything goes wrong during the repair process.
