Hi, not so much a solution to the problem, but a possible help. I've carried the steps out I've seen here so you can add a restart aero function to your context menu
and it works no problems on W7 Ultimate 64 bit. As always, back up your registry before you make any changes though. (It points to another website not under bleepingcomputer's jurisdiction, but it is still worth a look).
Also, if you're using multiple programs to perform the same function to improve performance for gaming (e.g. using Tuneup Utilitie's supposed 'turbo' function from the system tray icon's right click context menu along with IOBits Game Booster v2) - or anything else particularly demanding, then chances are there may be settings that clash within those two programs. One or the other is likely to be sufficient, if not better than using both.
You're not using third party themes are you?
