This may sound like a strange request, but i am looking for a windows 2000 professional unmodified original cd image (iso or whatever format is available). If i could get either an RTM image, or one with SP4 built in (don't know if microsoft ever ditributed one). I can't seem to find any information about one on technet (SHA1/filenames). I have four identical test machines (amd athlon64 3800 AM2/1GB DC DDR2800/160GB SATAII HDD/nforce405-6100/etc.) and would like to do an extensive side by side comparison of windows 2000/XP/VISTA/7 professional/business editions. Any information would be very helpful.
