I doubt that eviltechie...
I have tried every single tweaking in XP's Os and I have NEVER had a better result in speed in XP than 2K

The only "tweak" that actually works is not the "classic style" that mostly think... It is this one:

1. Click the start button and go to the Run window...
2. Type services.msc , (the Services windows will show)
3. Scroll down and double-click on the themes button
4. In General click the "stop" button and change from automatic to disabled

Now you wont have the exact look as 2K (like the classic style) but XP will now be VERY lighter and absolutely no eye candy except for the icon, also the logon (classic) will not start as the fisher price look like with the classic style, this I found very annoying...

In most benchmarks 2K beats XP in office productivity, speed (except Logon) and sometimes stability (mostly think 2K beats XP badly in stability)

XP only beats 2K in games and for me that is NOT important because "I'm not a Gamer"

eviltechie: if you have some tweaks that actually work (not like the one, change to classic style, and those stuff) please tell me, it would be definetely appreciated...

Thanks for the attention
