This kind of thing drives me nuts even though I'm not a gamer. I don't reboot very often, and it seems like nearly every time I want to reboot - especially if I'm in some sort of hurry, Windows wants to update a bazillion things.
Or maybe I'm impatient, so it always feels like I'm in a hurry when this happens.
And Flash wants to update so often, that I'm pretty sure I'll think my machine is hosed if I ever reboot and not get the request to update Flash. On the plus side, at least it's pretty quick.
In any case, it drives me nuts.
