I wonder if this permissions issue I saw is now causing other problems.

My start menu broke now. Clicking the Windows button, or hitting the Command (windows) key does nothing. Right clicking still works to bring up a different menu. And since all my games are on the taskbar, hasn't impeded the ability to play games, yet.

The only thing I do with this install is boot it, launch Battle.net or Steam and play a game. If the NVidia thing tells me I have a new driver, it gets installed. Windows self updates.
