"Normal" user can not disable update. The reason people complain about the updates and reboots they can not stop is because it works. MS surely has tons of statistics about how many % of user actually manage to run an outdated system.
So you wanna say you keep running windows 7 because you dont have the tech skills to turn off updates in win 10?
If that's the case I dont think there are many of you out there.
I run win7 on hardware that cant run win10 and I know people who run win7 simply because they like it more.
Normal user can change the location of the "Program Files" directory in the registry to disable (really break with an unsearchable error message) Windows Update. Weird, but doesn't require an Enterprise version or anything.
It put "normal" into quotes because I specifically wanted to excluded anyone who is willing to tinker with the system risking to break things or simply lacks the knowledge how to do it or how to figure out.
I'm fully aware that there are countless ways to stop windows from updating.
MS never attempted to make it super hard just hard enough so most of the people who absolutely should not turn it off are also unable to do so.
I would assume win7 users are the largest junk.
