..:: Step 1 ::..
Run regedit and navigate to HKLM>System>CurrentControlSet>Control>Session Manager>Memory Management>Prefetch Paramaters
The entry we are concerned about is EnablePrefetcher (which I have highlighted above). Notice that it is set to 3. This is standard for MOST default installs of Windows XP. The different settings for the prefetcher are as follows:
• 0 = Disabled
• 1 = Application Launch Prefetch
• 2 = Boot Prefetch
• 3 = Application and Boot Prefetch
For speed of booting, we want to set this parameter to 2. So double click the entry. Change the Value data from 3 to 2 and click Ok.

Once you’ve done that, you should go clean out your prefetch folder. This is locate at C:\windows\prefetch
Just select everything in this folder and delete it all. This clears all the old prefetch data that your computer had.
..:: Step 3 ::..
Reboot your computer. *NOTE* You will probably not notice a faster boot up time the first time you reboot. In fact, it may even be slower. This is due to the fact that since you cleaned out your prefetch folder, so Windows has to effectively “learn” what files to prefetch again. But subsequent reboots should be considerably faster.
And that’s it, you’re all done. When I did this little trick, my boot time decreased by almost 5 full seconds. I know that 5 seconds doesn’t seem like a lot to some people, but when you’re talking about boot times already being only 30 seconds or so. 5 second decrease equates to an almost 17% increase in performance!
