Tweak UI
Microsoft Tweak UI is a free application, released in 1996 by Microsoft for customizing the Microsoft Windows operating system's user interface. Tweak UI does not do anything that a knowledgeable user could not accomplish by editing the Windows Registry. However, Tweak UI provides a simple graphical user interface that most users find easier to use and less risky than editing the registry.
Tweak UI was a free download from Microsoft's website. It is one of Microsoft's many non-supported PowerToys.
History
Tweak UI started as a control panel applet available for download on Microsoft's website, released shortly after the release of Windows 95. It was originally written by Raymond Chen and later included in Microsoft's Power Toys collection, a set of tools developed by Microsoft's Shell Development Team.
An updated version of Tweak UI was included on the installation disc for Windows 98. According to Chen, this was deemed a "disaster" because it resulted in additional work for Microsoft's product-support teams when diagnosing problems. Therefore, Microsoft did not include the applet in Windows 98 Second Edition.
