Windows 10 1709 Update auf 1909

If you are running into issues with Windows 10 20H2, otherwise known as the October 2020 Update, this guide will explain how to roll back to your previous version of the operating system.

When upgrading to the Windows 10 20H2 feature update, one of two methods will be used depending on what version of Windows 10 is being upgraded.

If users are upgrading from Windows 10 1909 or older, then Windows 10 20H2 will be installed as a full update, which can only be rolled back within 10 days of being installed.

On the other hand, if a user was running Windows 10 2004, Windows 10 20H2 will be installed via an 'enablement package' that turns on features already part of the operating system but are turned off. 

How you upgraded to Windows 10 20H2, though, determines how you can uninstall and roll back to a previous version of Windows. Below, we have provided two different methods to uninstall Windows 10 20H2, the October 2020 Update, depending on your previously installed version.

How to uninstall Windows 10 20H2 and rollback to v2004

If you upgrade to Windows 10 20H2 from Windows 10 2004, you would have done so through a small enablement package that enables features already installed on the operating system.

You can uninstall the Windows 10 20H2 enablement package to roll back to Windows 10 2004 by following these steps:

1. Go to Start > Settings > Update & Security > Windows Update > View update history > Uninstall Updates, as shown below.
   
   View update history settings page

2. When the 'Uninstall an update' screen opens, search for the "Feature Update to Windows 10 20H2 via Enablement Package (KB4562830)' update and left-click on it once, so it's selected.
   
   Once you click on it, an Uninstall button will be displayed that you should click on to uninstall Windows 10 20H2.
   
   Uninstall the KB4562830 Windows 10 20H2 enablement package

3. After clicking on the Uninstall button, you will be asked if you are sure you wish to "Uninstall this update." Click on the Yes button to continue.
4. You will now be shown a small dialog box that asks you to wait while the enablement package is uninstalled.
   
   Waiting while Windows 10 20H2 is uninstalled

5. When it has finished uninstalling, you will be prompted to restart Windows 10. Click on the Restart Now button to continue.
   
   Prompt to restart Windows 10

After Windows restarts, Windows 10 20H2 will be uninstalled, and you will be back at Windows 10 2004.

How to uninstall Windows 10 20H2 and rollback to v1909 or older

If you upgraded to Windows 10 20H2 from Windows 10 2009 or older, then a full update was used to install the new operating system.

It should be noted that you can only uninstall Windows 10 20H2 and roll back to a previous version if you are within ten days of installing the feature update. If it has been 10 days or later, the 'Get started' button will be grayed out, and you will not be able to select it.

Windows 10 November 2021 Update (21H2) has been available since November 16, 2021, and you can upgrade to the latest version manually whether you have version 21H1, 20H2, 2004, 1909, or an older release.

While you shouldn’t rush the new feature update to avoid potential bugs and other problems during the early days, the update has been out for some time, and it’s now fully available, and you can upgrade manually in at least two ways using Windows Update and the Media Creation Tool.

If you have a device with versions 21H1, 20H2, or 2004, the best way to install the 21H2 release is using Windows Update because the new release of Windows 10 is a minor update based on version 2004, and you only need an enablement package to upgrade.

However, Windows Update will take longer if the device has version 1909 or an older release. If you want to force the upgrade, you can use the Media Creation Tool to perform an in-place upgrade, preserving your files, apps, and settings. This process is similar to using Windows Update or the Update Assistant tool.

This guide will teach you the steps to upgrade version 21H1, 20H2, 2004, 1909, or an older version to Windows 10 21H2.

• Upgrade to Windows 10 21H2 from version 21H1
• Upgrade to Windows 10 21H2 from version 1909

Important: These instructions will work whether you are trying to upgrade from version 21H1 to 21H2, 20H2 to 21H2, 2004 to 21H2, or from any other release, including version 1909, back to the original release (such as 1803, 1709, 1703, 1607, 1511, or 1507).

Upgrade to Windows 10 21H2 from version 21H1

To upgrade to Windows 10 21H2 (November 2021 Update) manually from version 21H1, 20H2, or 2004, use these steps:

1. Open Settings on Windows 10.

2. Click on Update & Security.

3. Click on Windows Update.

4. Click the Check for updates button (if applicable).

5. If your device is compatible with Windows 11 and has the upgrade notification, click the “Stay on Windows 10 for now” option to get the version 21H2 upgrade option.

   
   

6. Under the “Feature update to Windows 10, version 21H2” section, click the Download and Install now button.

   
   

   Quick tip: If the option is not available, it is likely, that the update is not ready for your computer.

7. Click the Restart now button.

Once you complete the steps, Windows 10 21H2 will install similarly to a regular monthly update on your device without a complete reinstallation.
