This question already has an answer here:
I'm currently experiencing a Windows 8 DoS. When this nag ribbon is open, I cannot use the machine:
I've tried closing the ribbon with ESC, ALT+F4, and a few others that used to close programs. I can bring up task manager, but I can't do anything with it.
I know I can force it to go away with a hard shutdown, but I don't like to do it because it could leave the filesystem in an inconsistent state. Also, it seems to come back on a regular basis so its not a good long-term solution.
What executable is producing the nag? I would like to delete it if possible.
