Booting Linux breaks Windows Aero in dual-boot

"I've had Windows machines which couldn't soft reboot, even without dual boot, meaning from Windows into Windows. You might try this out on your machine.

I've been searching for an explanation or solution for years, without success, until I changed machines. Everyone I mentioned this to was extremely surprised and had no ideas to contribute, both software and hardware specialists. I finally gave up and just did hard boots."
