Well i pretty much explained it in the steps above, basically just install PHM registry editor, then just go to the registry keys I mentioned above and change their decimal value to the one that is mentioned above. If you are really PPC illiterate, I strongly recommend you don't do it yourself as you might cause some damage. I recommend getting Tweaks2k2, or even just try it out (you have 3 uses, just make sure you do all the things you want then you wont have to use it for a while).
