Aero stopped working a few weeks ago. I've tried several things to try to get it working again
- Looked for but did not find on my computer the windows update that kills aero
- Changed the registry settings for aero settings
- Ran the aero troubleshooting app - got message that Window Manager Session Manager was not running even though it is

Oddly enough, aero does work after every update....until I reboot the computer.

Anyone have an answer to this problem. Thanks.
