If I switch user and log back in Aero will be disabled and I'll be back on Windows 7 basic theme.

If I go to personalize and troubleshoot it will say the the "Desktop Window Manager" is disabled.

It started happening... I dunno about a few week ago.

If I LOG off it and log back on it Aero will be fine, It only happens when I switch user.

I also reinstalled windows the other day, It was doing it before I reinstalled as-well.

So a fresh install didn't help..

If it helps I have an Nvidia Geforce GTX 670 FTW with the latest drivers.

I am already using "adjust for best performance" also, when I trouble shoot it reactivates the aero but the problem is if i want to switch user anytime i log back in i'll have to troubleshoot and reactivate aero again and its getting really annoying.

Also, This is my personal PC so I am admin.
