Windows 7 Aero theme's "greyed out" - no found fix - Super User

easily fixed by going into performance info tools, adjust visual effects and go to show best apperence otherwise go to for best performance and back again and it worked for me.

Thanks @tazz your SuperUser link got me on the right track. For me it wasn't the `Themes` service but the `Desktop Window Manager Session Manager` service which I had to restart. None of the other fixes here (or there) worked for me. I also updated Windows 7 Aero theme - no found fix - Super User
