GREAT NEWS for either Win7 or Win8.1 Pro! Way to stop those pesky GWX's!
I was just checking for updates again, since the last 'Update Client' didn't bork my machine, and this update just came in: https://support.microsoft.com/en-us/kb/3050265
Note the text specifically says (i added the red bolding, but the black bolding is original to the KB),
This update installs a new Group Policy object that enables you to block upgrades to the latest version of Windows through Windows Update.
Microsoft is making Windows 10 available for free for one year from the date of availability to Windows 7 and Windows 8.1 customers for non-Enterprise editions. If you have Windows 7 or Windows 8.1 Pro deployed in your organization, Windows 10 will be offered to you. Computers that have this Group Policy object enabled will never detect, download, or install an upgrade to the latest version of Windows.
You can configure this Group Policy object by using Group Policy (if the update is installed and if you use the updated WindowsUpdate.admx file by copying the file from where the editing policy is located). You can also do this by going to Computer Configuration > Policies > Administrative Templates > Windows Components > Windows Update, double-clicking Turn off the upgrade to the latest version of Windows through Windows Update, and then clicking Enabled.
Honey, I'm downloading it now, especially since all my prior HIDDEN updates are GONE. Maybe this is why? Who knows.
