Hey there. I am on windows 8,1, and had something happen today.... My keyboard is acting weird, when I press "escape" it goes to the windows 8 start menu, when I press "w" it closes the page I am on, and a bunch of other stuff. For the way it acts with"w" I think the PC thinks the "alt" key is pressed down. But it's not the keyboard itself, tried two diff ones and the on screen keyboard, they all do the same thing. Any ideas what is causing this and how to fix? Thanks! Posting from my iPad.
