Arie Slob of Windows-Help.NET passes along the news that a New TweakUI 2.10 for Windows XP is available. He’s got a nice list of the new features you’ll find there, plus links to the download site.
Be sure to read the documentation first. This update requires Windows XP Service Pack 1 or Windows 2003 Server. If you’re running XP and you don’t have SP1 yet, go to Windows Update and get it.
