Windows is tabbing me out and I can't work out why

[Roadkillv1]

Any time I'm playing a game windows will randomly tab me out to my desktop and make it a pain to get back in. The program I ran, as you can see, only tells me explorer is doing it. It just tabs me to my desktop, it's frustrating, and I don't know what to try to turn off as I can't work out what it is. It says 'false' under keyboard so it isn't being caused by an alt tab situation occuring somehow but...wtf is?
