Sting - First of all, what Win OS are you running; Vista,7, 8, 8.1?
I'm a MS Certified Architect. I doubt the update caused the issue; it sounds more like you got malware from that damn Dominoes ad they (WGT) embedded in the client. Happened to me the other morning after the ad played...it resized all my desktop and app icons to like 16x16 px and my game client was like 160x160 px in full screen mode. Then, after a reboot, I had the same issue you're having.
DO THIS and RUN system Restore, Sting.
If you're using 7 or 8 you'll need to expand More Details to view the menu at the top, if it's hidden.
Press CTRL + SHIFT + ESC. When Task Manager Pops up...choose FILE > Run New Task.
Type this command in the box: rstrui.exe and press OK.
Here's the screenshot, for anybody that thinks I'm joking..after the reboot..my entire desktop was blank.
