TweakAll is like Microsoft's Power Toy, Tweak UI, but on steroids. The first time that you run it it will give you the option of downloading plugins specific to your system.
(more info: http://www.abtons-shed.com/tweakall/tweakall.htm ) It allows you to hack into the Windows' Registry to take back some of the control which you, as a user,
should have. TweakAll offers some different tweaks to other, similar types of programs and it even allows you to tweak the settings for some of the popular video cards, like
Voodoo and nVidia TNT. The program offers 15 separate sections with a varying number of tweaks in each section. These sections can be removed from the tabbed list if
you don't want to access them (specially if you don't have one of the nominated 3dfx cards). There are sections for controlling the cache of your hard drive and also your
CD drive (including provision to increase the cache level beyond the Microsoft settings).
