First of all, this tweak only apply to those who only have one HDD on their primary IDE channel (nothing else on device 0 or 1) and a CD-ROM and/or DVD-ROM on the secondary IDE channel. Each time you boot Windows XP, there’s an updated file called NTOSBOOT-*.pf who appears in your prefetch directory (SystemRoot%Prefetch) and there’s no need to erease any other files as the new prefetch option in XP really improves loading time of installed programs.

1. Open bloco de notas.exe, type “del c:windowsprefetch tosboot-*.* /q” (without the quotes) & save as “ntosboot.bat” em C:
