How to Repair Windows 11 in 2025 (Step-by-Step Guide)

Windows 11 is a stable operating system, but like any software, it can run into problems from slow performance to random crashes and even dreaded BSOD (Blue Screen of Death) errors. Fortunately, Microsoft provides several built-in repair tools that can help you troubleshoot and fix most issues.

In this guide, you’ll discover 8 effective methods to repair Windows 11 in 2025. Whether your PC won’t boot, keeps freezing, or shows corrupted files, these solutions can bring it back to life.

Create a Restore Point First

Before attempting any repair, it’s wise to create a restore point. Think of this as a time machine for your PC if anything goes wrong, you can roll back to this safe state.

How to create a restore point:

  1. Search for “Create a restore point” in Windows search.

  2. Select the drive where you want to store the restore point, then click Configure.

  3. Enable Turn on system protection and allocate some disk space.

  4. Click Apply, then OK.
  5. Finally, click Create, assign a name, and confirm.

With this safeguard in place, you’re ready to begin the repair.

1. Repair Windows 11 Using Built-in Troubleshooters

Windows 11 comes with specialized troubleshooters designed to diagnose and fix common issues. For example, if your Wi-Fi keeps disconnecting, you can run the Network Troubleshooter.

Steps to use troubleshooters:

  1. Open Settings from the Start menu.
  2. Go to System > Troubleshoot.
  3. Click Other troubleshooters to view the full list.
  4. Select the relevant troubleshooter and hit Run.

💡 Tip: If you’re unsure which tool to run, you can try them all one by one until the issue is fixed.

2. Repair Windows 11 Using Command Prompt

For advanced users, the Command Prompt (CMD) offers powerful commands to repair corrupted files.

  1. Search for Command Prompt, right-click, and choose Run as administrator.
  2. Run the disk check utility to fix hard drive issues:
chkdsk /r
  1. Restart your PC when prompted.
  2. Reopen CMD as admin and run the System File Checker (SFC):
sfc /scannow

If SFC shows errors, run DISM (Deployment Image Servicing and Management) commands:

Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth

These scans can repair corrupted Windows components and restore system stability.

3. Repair Windows 11 Through Windows Updates

Sometimes, a faulty update causes the problem. If you notice crashes or lag after an update, you can uninstall it.

  1. Open Settings > Windows Update.
  2. Select Update history.
  3. Click Uninstall updates.
  4. Find the recent update and click Uninstall.

Alternatively, keeping your system up-to-date can also fix bugs introduced in older builds.

4. Repair Using System Restore

If problems persist, you can roll back Windows 11 to an earlier restore point.

  1. Search for Recovery in Windows search.
  2. Select Open System Restore.
  3. Choose Pick a different restore point and click Next.
  4. Select your preferred restore point and confirm with Finish.

Imagine this as “rewinding your PC” to a moment before the issue appeared.

5. Repair Drive Errors with Disk Check

Hard drive errors can slow down your PC or cause random crashes. Windows 11 includes a Disk Check utility to resolve this.

  1. Open File Explorer and right-click your system drive (usually C:).
  2. Select Properties > Tools.
  3. Under Error Checking, click Check.
  4. Choose Scan Drive and let Windows fix any detected issues.

6. Repair Windows 11 Using Memory Diagnostic Tool

Frequent BSOD errors? Faulty RAM may be the culprit. Windows has a Memory Diagnostic Tool to scan and repair memory issues.

  1. Press Windows + R, type mdsched.exe, and press Enter.
  2. Select Restart now and check for problems.

Your PC will reboot and automatically check for RAM issues, helping prevent future crashes.

7. Repair Windows 11 via Windows Recovery Environment (WinRE)

When Windows won’t boot, WinRE (Windows Recovery Environment) comes to the rescue.

  1. Go to Settings > System > Recovery.
  2. Click Restart Now under Advanced Startup.
  3. After reboot, select Troubleshoot > Advanced Options > Startup Repair.

This tool fixes startup issues and repairs essential boot files like the MBR (Master Boot Record).

8. Reset Windows 11 (Last Resort)

If nothing else works, you may need to reset Windows 11. This keeps your personal files but removes apps and settings.

  1. Open Settings > Windows Update > Advanced Options > Recovery.
  2. Select Reset this PC > Keep my files.
  3. Choose Cloud Download for the latest installation files.
  4. Confirm and click Reset.

⚠️ Warning: Always back up your important data before performing a reset.

Final Thoughts

Repairing Windows 11 doesn’t always mean reinstalling it from scratch. From simple troubleshooters to advanced command-line fixes, Microsoft provides plenty of tools to resolve common problems.

By following the methods above, you can fix performance issues, eliminate errors, and get your PC running smoothly again.
