I made the swap after they forced Windows 7 update behavior to change. You used to be able to download updates but you got to choose when to install them. Then they changed it to either they're on and fully automatic, or fully off.
At the time, I was running a computer repair company, and my work computer running Win7 was running a data recovery on an accidentally formatted drive for almost two days. After I had left and the program finished, Windows was all "Oh, the computer is idle now. Let me give you a 15 minute warning that I'm going to install updates and reboot if you don't cancel".
After the second time, I formatted my work computer. Shortly after, I did the same to my gaming PC. Haven't looked back once.
