Windows 10 21H2 (November 2021 Update) is expected to be available soon. However, if after the upgrade, the new version is having problems due to unknown bugs or compatibility issues, it’s possible to uninstall it to roll back to version 21H1 or an older release. However, the process will be different depending on the release you were running previously.

If the computer was already running version 21H1, 20H2, or 2004, you could uninstall the update quickly using the Windows Update settings. On the other hand, if you had an older release like version 1909, you will have to use the built-in recovery settings.

In this guide, you will learn the steps to uninstall the November 2021 Update to revert to the previous version of Windows 10 without losing your files.

Windows 10 uninstall option is missing

Windows 10 automatically saves a copy of the previous version in the Windows.old folder to roll back if something happens during each feature update installation. If the upgrade completes successfully, the Windows.old folder will be kept on the computer, and you can use the above instructions to remove the Windows 10 November 2021 Update.

If the Windows.old folder has been deleted manually or automatically, you won’t be able to uninstall the feature update. Usually, after ten days from the original installation, the system will automatically remove the previous setup files to free up space, thus removing the option to roll back.

If the option is missing, but you still have the files, something else is going on. In this case, you can still downgrade, but you will need to use a clean installation of Windows 10 using an ISO file that contains the older version you want to use. After the process, you can always try to reinstall the feature update again.
