8.1: disable tutorial?

I installed W8 in VMWare Fusion 6, and updated to 8.1. I now have tutorial popups that I can't dismiss. It seems to think I'm on a touchsreen, and tells me to swipe in from the side, when I am in fact _not_ on a touchscreen. Googling indicates that I need a registry edit to disable them.

Is this true? Any other way to turn them off?
