Getting the worst of Windows 7 - Install updates automatically (recommended)

Why doesn't my setting of NOT installing important updates automatically stick? Every once in a while it seems to pop itself back to the stupid position and does all kinds of nasty things in the middle of the night. From now on I'll start a counter how many times I'll go there to reset the setting back to the one I as system administrator chose.

All this rant is for the simple reason: I've lost data and precious working time trying to recover it. This morning I woke up and while roaming in the house in a semi-conscious state attempting to regain a thought, I noticed couple of LEDs glimmering in a place there shouldn't be any. My desktop PC was on and it shouldn't be. On closer inspection at 3 am it chose to un-sleep for the sake of installing Windows updates. This is yet another stupid thing for a computer to be doing (see my post about OS X waking up).

The bottom line is that the good people (fucking idiots) at Microsoft don't respect my decisions. They choose to force feed me theirs based on the assumption that I accidentally chose not to do a trivial system administration taks automatically. I didn't. I don't want to lose my settings, windows, documents, the list goes on.

The only real option for me would be to set up a Windows Domain. In Active Directory there would be possibility of fixing the setting and making it un-changeable. I just don't want to do it for a couple of computers. Idiots!
