Actually, whilst you'll not find anyone more pro Windows than me, my up-to-date Win7 laptop required 20 updates last night and it took 45 minutes to install them, due to two of the updates being mahoosive ones.
My work laptop tends to wait until I need to do a quick reboot in the middle of the day and catches me out by telling me it's going to install a dozen updates first. I've had it take over an hour before now. If I'm organised I try to tell it to reboot when I go home.
I've also been known to lean on the power switch for four seconds when that happens and give it something else to think about when it wakes up.
