What do I do with my Windows XP computer that won't shut down after it finished installing updates?

Episode 1079 (16:23)

Dennis from San Diego, CA

Dennis got an old Windows XP Machine, but when he tried to update it, it got stuck on the black Windows XP screen and wouldn't shut down. Leo says that once the updates run, it should be OK to just turn it off. If it won't shut down on its own, after awhile it's ok to turn it off with the power button.
