Win-Key + Arrow keyboard shortcuts no longer working

Question

I spent the night tweaking my computer. I got a few performaAnce gains but unfortunately, the windows key keyboard shortcuts no longer work.

How do you fix them? What service requires them?

I'm mainly interested in the ones that move and resize your window to half the screen

I'm running windows 7.

Thanks

That feature is called "Aero Snap" and here is a webpage about how to enable and disable it :) http://www.winhelponline.com/blog/enable-and-disable-aero-snap-docking-windows-7/
