I installed it. Very, very nice but how do I turn it off? I canot get it out of my icon tray. I even Googled for a solution. Nada, zilch.
What to do?
Wow! This did it. I was playing a 3d game perfectly in xp but after i came to windows 7, the game was like a group of pictures. thanks a lot.
I didnt play it but its look nice. I got one question, is it for free?
of course its free dont worry.
