Part 36: Restart, restart, restart

I was out of the office for a couple of weeks and, apparently, Windows took it upon itself to download some update. And now that it has done so, it prompts me, every 15 minutes to restart. But it gives me 15 minutes to say no. What I really want to do is go about my business today, and restart at the end of the day when I shut down my computer. But "restart later" simply resets the clock.

Please, Windows, why can't you give me a "restart at my own goddamn convenience" button?!
