A. TWEAKUI is part of the Power Toys set released for Windows95, however TWEAKUI (and a number of the other utilities) also runs on NT4.0. The utility basically puts a graphical front end to some of the more useful Registry settings and allows the user to remove icons from the desktop (such as Rubbish Bin), automatically login and many other useful config options.

Download it from http://www.microsoft.com/Windows95/downloads/contents/WUToys/W95PwrToysSet/Default.asp, then run the file and a number of files will be created. Right click on the TWEAKUI.INF and select install, and a TWEAKUI option will be in the control panel.
