some say it does. i was using win 7 on a laptop i was borrowing from a friend, but it kept crashing while reading and writing the pcm. so i stopped using it. i blame the laptop tho. older acer brand.
my desk top has its xp HD and the new HD with win7 on it, so i switch to the xp OS and was using the desk top with my off board set up for a while.
i just picked up a used gateway lappy running vista for 25 bucks. and it works fine with dhp.
if you search CL theres Xp laptops for sale for like 50 bucks or so. how this one went from 50 to 25, guy said it was xp. got there it was vista. hes like screw it 25 and its yours. deal!!! it came with Xp and was up graded to vista so if it came to it i was gonna reload xp to it. but vista is fine so far.
all but the battery life as expected, its needs a new one.
and the best part of all. when i registered the dhp to this new laptop, being ive done it a few times already, it went though on the very first shot.
