Hi Guys,
I'm running a new WinXP machine at work and was having trouble loggin into our network so I became desperate and logged in with my friend username and password. Now I want to loggin in with mine and I can't. Everytime I fire up the system XP automatically logs in her name. I heard the only way to stop xp from doing that is by going into the Registry and manually getting rid of that file.

Is this true? And if it is how do I do it?
If it is not true, what do I do?

Thanks in advance for you help.

your friend's account probably has autologin enabled. to disable it, you'll have to do a search on winxp sites for the registry instructions and reverse it. Alternatively, you could download something like WinXP PowerToys or TweakXP and you can disable it from there.
