Can't say I've ever had that issue. and my PC (while running the RC version, and the RTM / Retail has been up for 44 days or more at a shot)

Ensure your video card drivers are up-to-date.

I'm experiencing the same thing, and have no clue why. Usually changing the power plan then changing it back seems to work

My gfx driver is the latest already.

Welcome to the forum rOtsfactor,
Have you tried the troubleshooter in control panel?

I've only had this happen one time (Explorer showed a list of open windows instead of the small pictures of each window), and I was running an older program at the time. I wish I could remember what it was, but I can't. It seemed to me that having the older program running somehow messed with Aero (possibly through a DirectX conflict), because the Aero functionality returned to normal just as soon as I exited.

I found out my problem is with the foobar in particular the "show icon in taskbar" option

once i change that option, i no longer have this problem

Squall343, I believe it's a system wide bug. Somehow someway after sometime the aero previews stopped working, and DWM doesn't re-initialize the whole preview method. It should re-initialize the previewing even if you check "show icon in toolbar" in your foobar. For another instance, if somehow Aero composition got disabled by a legacy program, it should re-initialize no matter what.

use aero peek to preview the desktop
I'd like to know how to 'turn off' (untick the ghosted ticked tickbox) the "use aero peek to preview the desktop" as displayed in the 'Taskbar and Start Menu Properties' pane. I don't use aero and suspect this shouldn't be ghost ticked.
