Some users report that this will not work.
It does not work. The setting even lists "Windows Vista only" next to it. It worked pre-RC, but not anymore.
The other option given in another thread is to set ExtendedUIHoverTime to a value high enough that they take a long time to appear during mouse-over, but that doesn't work in all cases, as I already noted.
The worst part is that I don't even use the "grouping" feature. I have my taskbar set to "never group" with small icons. As such, there's never more than 1 preview window to select for each taskbar item, which makes it useless.
I can see how it would be useful if you used grouping, but I don't like the grouping at all.
In Explorer.exe, I did find:
TaskbandExtendedUI
... which also appears in aero.msstyles. I'm not sure where to go with that, though.
I find it useful when you have another program open like a torrent behind say your browser, because you can just hover over the preview and will allow you to see what's going on in the other program without actually having to click on it and then you can just move your mouse back to your browser and carry on.
