Since Windows XP, Windows creates a prefetch file every time you run an app for the first time. This file contains data the OS needs to speed up the app's load time whenever you run it. And this is a big help during the startup process since it helps Windows load faster.

The History and Future of DRAM Architecture in Different Application
WebDDR2 is the next generation of memory developed after DDR. DDR2 increased the data transfer rate referred to as bandwidth by increasing the operational frequency to match the high FSB frequencies and by doubling the prefetch buffer data rate. There will be more about the memory prefetch buffer data rate later in this section. Web1.1.3 Prefetch, Burst Length and tCCD DDR3 SDRAM employs the 8-bit prefetch architecture for high-speed operation though DDR2 SDRAM employs 4-bit prefetch architecture.
