PowerToys are free programs that provide simple yet powerful functions to Windows XP owners.

The best and most useful tool in the set is Tweak UI.

TweakUI 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. Version 2.10 requires Windows XP Service Pack 1 or Windows Server 2003.
