The easiest way to block the Windows 11 update on a Windows 10 system is by adding a policy via the Registry.
In HKEY_LOCAL_MACHINE, navigate to SOFTWARE\Policies\Microsoft\Windows
Create a new Key named WindowsUpdate
Add the following items in the WindowsUpdate key:
- REG_DWORD named TargetReleaseVersion with a value of 1
- REG_SZ named TargetReleaseVersionInfo with a value of 21H2
- REG_SZ named ProductVersion with a value of Windows 10
Below is a registry file example. You can also download a copy if you’d like.
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate] "TargetReleaseVersion"=dword:00000001 "TargetReleaseVersionInfo"="21H2" "ProductVersion"="Windows 10"
If you are using ManageEngine’s Desktop Central, you can create a configuration to deploy to computers with the Desktop Central agent. Here’s an example of the configuration in the Manage Engine Desktop Central web administration panel.
