Has anyone had any problems using Tweak UI on XP? After installing it from MS's Power toys site and using it the first time I lost my logon name in XP's next startup screen. There was no option to logon at all. Re-starting in Safe Mode and using a System Restore point prior to Tweak UI fixed the problem, but at the expense of Tweak UI.
The only thing I did in TUI was using the option to remove the name from the welcome screen, so I'd guess that is the problem.
