I'm fairly certain you can accomplish it with a pro license as well.

I'm on Enterprise, and you can't actually turn it off permanently, after a time (maybe a reboot, or scheduled that i can't find) it just turns itself back on, and usually knackers my nvidia drives, even though i have it set to not update drivers, and even though i killed the medic service as well ffs.

Found a trick where you basically remove windows access rights to wuauclt.exe and wuaueng.dll, causing an error code 5 whenever it tries to run its update service.. so far its been stable. Not sure if this would work for other versions.
