Tweak Ui from Microsoft is a PowerToy that lets you change system settings in Windows XP default user interface, including mouse settings, Explorer settings, taskbar settings, and more. Customize your Windows user interface.
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).
So what can you do with this wonderful Toy? All types of things, actually. You can configure various UI effects, such as menu fading, error beeping, cursor shadow, and the like. You can configure the mouse, the taskbar, and the desktop. You can edit common dialogs boxes, and determine the location of special shell folders, such as My Music, My Pictures, and the CD Burning cache. The list goes on and on, all of it extremely useful.
I strongly recommend that all Windows XP users get this PowerToy and experiment with its myriad of features. And check out the other Toys that are also available.
Tweak UI Version 2.10 requires Windows XP Service Pack 1 or above / Windows Server 2003. If you have a Windows XP system without any Service Packs installed, download Version 2.00.
