When you first boot-up their is no welcome screen it simply goes into the administor profile. No password or anything. If you log off as Admin then the other profiles come up and YES you can log into them. Question is this Admin profile is the one I set up for me, but unless I reboot, their is no way that I can renter this profile. What would be ideal would be to simply change the way this profile operates (welcome screen, and user profiles (3)) and if that happens then change the name from admin to mine.
Try downloading a program called TweakUI Powertoy from www.microsoft.com/windowsxp/pro/downloads/powertoys.asp And have a look at the login section. CJC
