The Windows shell-development team did some extra programming and put together a set of tools called Power Toys. If you're a power user, go ahead and try them out, but be forewarned that Power Toys aren't supported by Microsoft because they're not part of Windows. This group of "toys" lets you adjust your Windows user interface, including menu speed, window animation, and Microsoft Internet Explorer. This PowerToy gives you access to system settings that are not exposed in the Windows XP default user interface, including mouse settings, Explorer settings, taskbar settings, and more.

Tweak UI gives you access to a number of settings that are hidden away in Windows. It is part of the oddly named PowerToys utilities that are provided by Microsoft itself (although it doesn't support them).

Tweak UI allows you to change the way Windows looks and works. For instance, you can change things like the speed at which the mouse wheel scrolls and if a specific user should be automatically logged in whenever you start up Windows (a big timesaver if you are the only person to use a PC, and hate having to type your password every time you reboot).

The license of this software is Freeware, you can free download and free use this system optimizer software.
