I usually don't use the windows 7 aero features. In fact I right clicked on the computer icon, went to advanced system settings, chose the advanced tab, and clicked on the settings button under performance. I then chose "adjust for best performance ".
After that, I decided I wanted to use some of the Aero extras. so I went back to performance settings and chose " adjust for best appearance " but even after restarting I still can't do the thing where you hold the windows key down, and then hit the tab key to scroll through open windows. holding down Alt and hitting the tab key works, but I wanted to use the windows key.
I even looked at my settings in "adjust for best performance" and everything is checked. here's a screen shot
Any ideas what I'm missing?
