Windows 10 files have already been downloaded and a Windows Update prompt which can't be killed in Task Manager, or seemingly from anywhere else, is giving me the option of either scheduling the upgrade for later or doing it right now.
I want to hold off indefinitely and so I've left it as is without confirming a date or time for the last handful of days and I haven't rebooted since as I'm afraid if I do it'll start the upgrade. A fellow user, Mark Berry, was able to get his customer's PC to stop trying to upgrade to Windows 10 here Tell Windows 7 to Stop Trying to Upgrade to Windows 10? but it was a Windows 7 machine. I'm on Windows 8.1 and the registry values do not mirror Win 7's 100%. Is this method also possible on Windows 8.1? If so, which values do I need to delete or modify and are there any other steps I need to take prior to doing so?
