The preview desktop working has stopped working for me. I can still click it and minimize all programs, but I don't have the transparent preview option. I now trying to reinstall my graphics drivers but windows keeps on interfering by installing drivers of it's own. Any suggestions?

You should be able to cancel windows loading drivers. I don't think it's a driver issue, anyway. Right-click the taskbar and you'll see a show desktop option. In that same menu, select Properties, and you'll see options for desktop preview. Also, from the Start Button, right-click Computer, select Properties, Advanced System Settings, and you will see performance settings. I use Let Windows Decide. Good luck. Bob

Thanks for the suggestions Bob. My preview desktop option under the taskbar properties was already ticked, so I went to the performance settings page you recommended. I had the let windows choose what's best for my computer (which had thumbnail previews disabled for some reason). I then clicked on best appearance, then on let windows choose what's best for my computer, and my problem has been fixed.
