Found it on neowin. I had to turn it off because it makes things a bit confusing when you see windows from behind that clear. :(
How to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
Add DWORD HideBlur with the value of 1
Now Ctrl+Shift+F9 twice.
Doesnt work on taskbar
My screen goes completely blurry when I move my taskbar to the top of the screen. I've got the latest graphic drivers for my card, etc but can't figure out why it's doing that.
Also, WLM pops up every time I minimize firefox or any app.
