Re: Last Windows XP Update
the major problem with MS is the lack (supposedly until Vista) of support for true (hardware supported) protected-mode. and every time they did put in support, they do some funky things that require a "normal" user to run in protected mode.
the entire design is one giant security loophole from day 1 and they knew it.
they didn't *have* to do it, but it was a market strategy (for 3rd party support).. along with their amoeba approach to growth (find a victim, er 3rd party, who has done something better than you, then swallow them whole)
