I have the auto-updater disabled and just run a check manually once every couple of weeks.
^^^ This is how I have always set up any computers I have that run any type of Windows OS
--------------------------
Colmbo, not sure if this might be causing it or not, but some of the Soundcard manager or sound Software manager programs have the ability to throw out a pop-up whenever you plug in your headphones or plug in your microphone.................. and will throw up another pop-up if you was to unplug your headphones or microphone, which will cause the game to minimize.
Their usually is a checkbox in the software manager to turn this feature on or off, so that plugging in or unplugging headphones or microphone will not cause a pop-up
hope this helps Good Luck!
