I assume you're referring to XP? XP uses many tricks to boot fast. One thing Microsoft did is to build a prefetch cache which keeps track of the DLLs and EXEs loaded at startup and reorganizes them on the disk. It's clever, and it works. Nevertheless, they're still loading a lot.

Read the sections on boot up performance for more details. Ever watched an XP machine boot compared to a Windows 2000/NT machine? XP almost never lets the hard drive stop. It keeps looking for the next thing to process even though the OS is waiting on some hardware to finish initializing. 2000/NT will load drivers, wait, load more, wait, load more, wait, etc.
