Thinkpad crashed, it created second Administrator profile, normal profile won't load

[strifeknot]

My Thinkpad T400 freezes up once every week or two, necessitating a hard shutdown. After the most recent crash, Windows XP created and booted to a new adminstrator profile that never existed before. I'm given no option to boot to my normal profile, which is the only one that existed before this incident.

When I look at the user profiles in the Control Panel, I see my original profile there, but I have no option of deleting the new, duplicate administrator profile, or of instructing the system to boot to the original profile.  The original profile is naturally also an administrator profile.

Under User Profiles on the Advanced tab in System Properties, my original profile and the new one are listed, but nothing can be changed there on either one.

I can get to my original profile only after logging off the new administrator profile and typing my original profile name in.

Has anyone ever heard of this happening or know of a fix for it? I couldn't find an answer on Google.

It turns out XP has a master administrator account that's normally hidden. Why the computer booted to this account after the last crash, I still don't know, but I found a way to automatically boot to my normal account. There's a tool called Tweak UI that allows one to configure which account to boot to. Works like a charm.

I'd still like to know why this happened in the first place.
