Don’t get me wrong; I think Windows 10 is a reliable operating system, and I think Microsoft showed it too can be altruist by conforming to a well-established industry norm—at least until the summer of 2016. The problem is compatibility. Unfortunately, many software developers are as quick to adapt—think “compatibility mode” in IE.
If you wish to preserve your sanity, there are Group Policy settings that can stop this popup from, well, popping up. Before we begin, however, there is a prerequisite. If using Windows 7, Windows Update 3065987 must be installed. If you’re using Windows 8, Windows Update 3065988 must be installed. Same goes for equivalent server versions.
ON PRO, ENTERPRISE AND ULTIMATE EDITIONS
Using Local Group Policy Editor (GPedit.msc), locate the policy path:
Computer Configuration > Administrative Templates > Windows Components > Windows Update Policy
and enable the setting:
Turn off the upgrade to the latest version of Windows through Windows Update.
ON OTHER EDITIONS
Using RegEdit, navigate to the following subkey:
HKLM\Software\Policies\Microsoft\Windows\Gwx
and add the following DWORD value:
DisableGwx = 1
A word to the wise, RegEdit is no place for the meek. Exercise caution when working with the registry.
