Yep, that's right. I formated my hard drive with Windows XP on it and installed Windows Millenium.
This is only on the machine that my kids use. All they run is educational software and I got fed up with lots of titles not working under Windows XP. I guess many of the publishers still target Window 9x since there's a lot of it around still in schools. You think that they would at least do minor upgrades or patches to have it run under XP but no, they don't seem to.
It was a bit of a time warp installing it and remembering where everything was in this version. Microsoft, please get the education market to catch-up with you.
