I downloaded Windows Vista Release Candidate 1 from the Microsoft Customer Preview Program and just finished installing it on my Shuttle. Back in June, I had downloaded Beta 2, but never got around to installing it.
RC1 installed easily on an empty partition and also installed a boot manager that allowed me to boot to my “Earlier Version of Windows,” XP. I used my Beta 2 product key and activation worked without any problems.
After logging in, the desktop presents the “Windows Welcome Center” a place to start jerking the settings around.
Viewing the computer details displays a hardware and network overview and the resulting calculation gives the Windows System Performance Rating, in my case 1.0. I guess I should be happy it actually runs on my computer.
