How to block Windows 10 Version 20H2 Upgrade
You can stop your Operating System from updating to the new version. Follow the various options given below to keep your Windows 10 to the version it is on.
Pause updates for 7 to 35 days
Users can pause their Windows Update service from 7 to 35 days, depending on how long they want to pause. This will pause all features and security updates for a set time period. This approach will prevent your Windows 10 version from upgrading to 20H2 for a maximum of 35 days only. After that, Windows will begin to download all updates as usual. You can also resume downloading the updates by clicking on Resume updates in the Windows update window.
Postpone all feature updates for up to 365 days using Group Policy
You can use the Group Policy Editor to stop your Windows 10 from updating to v20H2 for up to a year! If you are running the Home edition, you will not have a Group Policy Editor by default. Here is how you can install the Group Policy Editor on the Home edition of Windows 10. Your computer will now stop receiving automatic Windows updates for the said amount of days. To check that the settings have been applied, you can navigate to the Windows Update page in the Settings app and see a message stating “Some settings are managed by your organization.” To revert the changes, you’ll need to select Disabled from the same policy setting and then select Not Configured.
Enforce PC to stay on the current build using the Group Policy Editor
You can also force your computer to stay on the current version of your Windows 10. This is also achieved through the Group Policy Editor. With this configuration, your OS will stay on the current version while installing Windows updates. Any update that changes the version of Windows 10 will not be installed.
