One evening I turned on my computer, and all the Aero effects of the desktop had simply gone away. I am pretty sure some auto-updates installed when I turned the PC off the night before.
Any idea why this happened, and how I can get Aero to come back? I should note that the Windows Color and Appearence option for Aero under my desktop settings are disabled, so I can not simply click it on again.
Some research indicated that iTunes / Quicktime were the culprits, but upgrading them did not solve the problem.
