Q. How can I add the Windows XP Tweak UI PowerToy to the Control Panel?

A. After you download TweakUI at the Microsoft PowerToys for Windows XP Web page and install it, tweakui.exe will be located in the \%systemroot%\system32 folder. To add tweakui.exe to the Control Panel folder, paste the following listing into a text file (name it tweakui.reg) or download tweakui.reg at Download, then execute it by double-clicking the file. When you open Control Panel, you'll have a TweakUI link.
