How to block Windows 10 Version 21H1 from installing

Pause the update for 7 to 35 days

If you don’t want to update your device, Microsoft lets users pause the updates for up to 35 days. This will pause all features and security updates for the set time period.

  1. Navigate to the following:
    Start Menu –> Settings –> Update & Security –> Windows Update
  2. Go to Advanced Options and select a date to pause the updates until then.
    Pause Windows 10 Version 21H1 Update

This approach will help you prevent 21H1 updates from installing on your PC. However, this will also prevent all other updates from being installed as well. Once the 35 day limit is reached, you will get the following error message:

“The pause limit has been reached. You’ll need to install the latest updates on this device before you can pause again.”

Postpone all feature updates for up to 365 days using Group Policy

  1. Press the Windows key + R, type gpedit.msc, and press Enter.
  2. Navigate to the following from the left pane:

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 settings and then select Not Configured.
