Hi There,
As a computer tech, I checked out the guide. There is really nothing new here that couldn’t be applied to XP with the exception of Ready-Boost and UAC. I run Vista on a newer laptop and did most of this and more already. The biggest thing is Services which is not for the faint of heart. I haven’t messed with them much on Vista, but by default there are ALOT turned on. I have an older XP laptop I tweaked, that runs with 15 services, but my Vista laptop runs 40-45 including the Virus Scanner. Thanks for the link!
