I called it "the most frustrating thing about Windows" -- forced automatic updates that lock you out of your computer until they're done. 

Last March, Microsoft made some pretty big strides toward solving the issue by letting you snooze an update indefinitely, but it still wasn't quite enough. In the 16 months since, I've still had a couple of instances where my computer tricked me into an update or wrested away control at a particularly inconvenient moment.
