IIRC one of 2000s main design advantages is that when a installer tried to crap various dlls into the windows directory it redirected them back to their own install and only used them for that program. This basically solved the dll hell problem that tended to rot 9x installs after 6 months. I was a cheap ass but I remember ponying up for extra ram and switching to 2000 quite early which is something I never do these days.
