Windows domain policy to disable windows 10 update

Group Policy, change the setting "Turn off the upgrade to the latest version of Windows through Windows Update," which can be found in Computer Configuration / Administrative Templates / Windows Components / Windows Update.

Doing so sets the registry value described in the rest of this step. Note that for Home versions of Windows 7 and 8.1, where the Group Policy editor is not available, editing the registry is the only option.

To make this change with Regedit, navigate to the following key.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate

Important: If that key doesn't exist, you'll need to create it.

Create a DWORD value called DisableOSUpgrade and set it to 1. (If that sentence makes no sense, you probably shouldn't be using Regedit.)
