My cat walked across my computer and brought up "Windows Mobility Center".
Looked in Help and support, and it doesn't show how, but does have a link.
What did my cat do?

My cat walks across my laptop all the time.One time he turned my wireless off and it took me a day to realize what happened. Sorry I don't have answer for you but I feel your pain :)

Instead of kids saying their dog ate their homework, they will say,"My cat deleted my homework"?
