I took a snip from ExtremeTech and pasted it below. You probably want to look at the whole article though. Some excellent information.

XP also speeds up and the boot process and optimizes the launch of programs by using prefetching. Windows observes the code and programs that are used immediately upon bootup and creates a list of data to prefetch very early in the boot process. Similarly, as individual programs are launched, Windows keeps track of different files and components are accessed. The next time the application is accessed, Windows prefetches the necessary items to expedite the application's launch.

The prefetch optimizing code exists both within the XP kernel and the task scheduler service. The kernel keeps track of pages that are referenced by a given process immediately after the process is created. The service transforms the recorded pages into prefetch instructions for that process. The next time the process is created, the kernel executes the prefetch instructions, speeding up the creation of the process.
