How to Fix Windows Update Stuck at 100% (Step-by-Step)

Windows updates are essential for keeping your system secure and efficient, but sometimes they get stuck at 100% and refuse to complete. If you’re facing this issue, don’t worry! This guide provides step-by-step solutions to fix stalled Windows updates.

1. Be Patient – Wait It Out

Before taking action, give the update some time to finish. Some updates, especially large feature updates, can take longer than expected.

2. Restart Your PC

A simple restart can resolve temporary glitches.

• Press Ctrl + Alt + Delete and choose Restart.
• If your PC is unresponsive, hold the Power button for 10 seconds to force a shutdown, then turn it back on.

3. Run Windows Update Troubleshooter

Windows has a built-in troubleshooter to diagnose and fix update issues.

Settings > Update & Security > Troubleshoot > Windows Update > Run the troubleshooter

4. Restart Windows Update Services

Using Command Prompt:

1. Open Command Prompt as Administrator.
2. Type the following commands one by one:
   net stop wuauserv
   net stop bits
   net stop cryptsvc
   ren C:\\Windows\\SoftwareDistribution SoftwareDistribution.old
   ren C:\\Windows\\System32\\catroot2 catroot2.old
   net start wuauserv
   net start bits
   net start cryptsvc
3. Restart your computer and check if updates work.

5. Free Up Disk Space

Windows updates require sufficient storage. If your disk is full, clear up space.

• Go to Settings > Storage and delete unnecessary files.
• Run Disk Cleanup by typing cleanmgr in the Run dialog (Win + R).

6. Use Safe Mode to Complete Installation

1. Restart your PC and press F8 or Shift + F8 before Windows loads.
2. Select Safe Mode with Networking.
3. Let the update finish in Safe Mode, then restart your PC normally.

7. Manually Install the Update

If the automatic update is stuck, download the update manually.

• Visit the Microsoft Update Catalog.
• Download and install the latest update for your system.

8. Reset Windows Update Components

1. Open Command Prompt as Administrator.
2. Type: DISM /Online /Cleanup-Image /RestoreHealth
3. Run: sfc /scannow
4. Restart your computer.

9. Check for Corrupted System Files

Corrupt system files can interfere with updates.

1. Open Command Prompt as Administrator.
2. Run: sfc /scannow
3. Wait for the scan to complete and restart your PC.

10. Perform a Clean Boot

Sometimes, third-party applications interfere with updates.

1. Open Run (Win + R) and type msconfig.
2. Go to the Services tab and check Hide all Microsoft services.
3. Click Disable all and restart your PC.

11. Reinstall Windows (Last Resort)

If nothing works, consider reinstalling Windows.

• Backup your important files first.
• Use a Windows installation USB to perform a clean install.

Conclusion

Windows updates stuck at 100% can be frustrating, but with these troubleshooting steps, you should be able to resolve the issue. Keep your system updated to ensure stability and security.
