Windows XP contains many optimizations specifically geared toward fast
booting and shutdown. IIRC, the main one is that most driver
initialization is done in a manner about as parallel as possible.
(This is in striking contrast to Linux, whose startup script runs
pretty much everything serially.) Windows also records statistics
about program disk usage and rearranges sectors on the hard disk to
make program startup faster. I'm sure there are other things I don't
know about.
