I'm not completely sure if he'd appreciate being bugged about it, but if you can't find the stuff I think Mr. K has it. I'm not 100% sure. I have 7 as well, but it only has a 50 gigabyte partition because I run most of my Windows programs in a virtual machine of XP under Mac OS X Snow Leopard. If someone is stuck completely, though, with Lemmings and Windows 7, the partition *should* be large enough for testing Lemmings stuff. however, I'd only work when I want to play SPORE (which, for a variety of dumb reasons courtesy to EA, is installed on the Windows partition because of EA's DRM crap. Game exists for both Windows and Mac but deauthorization tool exists only on Windows.
I've had this computer for a little over a week, but it's already been better to me than my old one was.
