How to Repair Windows 11 Using Command Prompt: A Step-by-Step Guide

If your Windows 11 computer isn’t working properly, you can often fix it using the Command Prompt. This involves using some special commands to check for and repair any issues with your system files. By following these steps, you can get your PC back to normal without needing any advanced technical skills.

How to Repair Windows 11 Using Command Prompt

In this section, we’ll walk you through the steps to repair your Windows 11 system using the Command Prompt. This should help fix various issues related to corrupted or missing system files.

Step 1: Open Command Prompt as an Administrator

The first step is to open Command Prompt with administrative privileges.

Right-click the Windows Start button, then select "Windows Terminal (Admin)" or "Command Prompt (Admin)" from the menu. This ensures you have the necessary permissions to run system repair commands.

Step 2: Run the System File Checker (SFC) Tool

Type sfc /scannow and hit Enter.

This command will scan your system files and replace any corrupted or missing ones with the correct versions. It might take some time, so be patient and let it run its course.

Step 3: Use the Deployment Imaging Service and Management Tool (DISM)

If the SFC tool doesn’t fix the problem, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.

This command will check for any issues with your Windows image and repair them if necessary. It uses Windows Update to download the necessary files, so ensure you have an internet connection.

Step 4: Restart Your Computer

After running the repairs, restart your computer to apply the changes.

A simple reboot can help finalize the repairs made by SFC and DISM tools. Make sure to save any open work before restarting.

Step 5: Check for System Updates

Once your computer has restarted, make sure to check for any available system updates.

Go to Settings > Windows Update > Check for updates. Installing the latest updates can help prevent future issues and improve system stability.

After completing these steps, your Windows 11 system should be smoother and more reliable. If issues persist, you might need to seek professional help or explore other troubleshooting methods.
