What do I do with a stuck update?

Episode 1028 (2:30:21)

Joyce from Bakersfield, CA

Joyce's laptop stopped installing updates. It keeps looping during configuration. Leo says Joyce has a stuck update and it can be concerning because it could indicate malware is on her computer. She's thinking about just buying a new computer and giving her old one to her son. Leo says that's a good idea, but she should just make sure she wipes the hard drive and install Windows fresh so they don't have access to her data. Should she upgrade to Windows 8? Leo says that moving to Windows 8 is a good idea, but Leo suggests getting a laptop with Windows 7 and wait until Windows 9 comes out.
