In the last day or so, every time I boot my Win 7 Home Premium x64 VM, I get a message saying that Windows has disabled Aero because Parallels Tools isn't compatible, or something. I can run the Areo Troubleshooter, which reports that the "Desktop Manager" was disabled and turns it back on, restoring Aero. I have to do this every time I boot. I'm running Parallels 6.0.11822. Any ideas? This is really annoying.
