How to uninstall Windows 11 when PC doesn’t start

Did you upgraded to Windows 11, and now, it doesn't start correctly? Here's how you can remove the new version and restore the previous version.

Windows 11 uninstall via Advanced startup
  • To remove Windows 11 if it doesn’t start, open Advanced startup > Troubleshoot > Advanced options > Uninstall Updates > Uninstall latest feature update.
  • Then click the Uninstall feature update button to roll back to Windows 10.

If after you upgrade to Windows 11 from Windows 10, the laptop or desktop computer no longer starts due to problems, you can uninstall and roll back to the previous version using the Advanced startup available through the Windows Recovery Environment (Windows RE). However, there is one caveat, Windows 11 (version 21H2) only gives you ten days to uninstall the new version. After ten days, the only way to undo the upgrade is by clean installing the previous version.

In this guide, you will learn the steps to uninstall Windows 11 through the Advanced startup settings when your device does not start correctly. If you still have access to the desktop, you can downgrade using these steps.
