I have seen many tips to improve boot time but this is by far the worst. Unlike the majority who read this, I actually understand what it does. Steps 1-5 create a script that deletes the “NTOSBOOT-B00DFAAD.pf” file on computer shutdown. This file was specifically designed by Microsoft to optimize boot performance. How anyone could believe that deleting this file would improve boot time is baffling. It could only come from someone with a very twisted understanding of how prefetch works. Be very sure, doing this will not improve boot time, it will degrade it - possibly seriously. Steps 6-10 will remove a short delay in bootup, probably not noticeable.
This "tip" can be found on many web sites, usually with the exact wording. No one claims any knowlege of how it is supposed to work. Obviously the original author had absolutely no understanding of how prefetch works. If it actually worked, why did Microsoft not implement it? Does the author believe he understands the system better than Microsoft?
