Tell us the setup, make and model of the system. You say, dual boot and boots straight into XP, but that doesn't sound right, so step through the process, eg Dual boot option screen, which other OS is listed there?
When you select XP from the dual boot screen what happens then? You are taken direct to your Desktop without the XP Welcome Screen?
Is this your XP's own Administrator account, or did you set up your own Admin capable account and it is logging into that. Just a note if this is XP's own Administrator account, what happens if that account gets corrupted? How do you then access the OS to repair it, or retrieve your files apart from via the other dual boot option?
If this is your own Admin capable account, have you at some time bypassed the login screen? The method to do this is given here;
Perhaps you can check that, and reverse the steps.
If you used a utility like TWEAKUI for XP, I would use that again to reverse the steps.
Once you have your own user account set up properly, that is, Welcome Screen, password required to be entered, then try creating a Limited User account for your son.
Tried searching the data base but could not make any of the threads fit my situation.
When I start up, through a dual boot, I go straight into my xp desktop. Been that way for years. No sign on screen just straight to my desktop. My son wishes to use the computer so I tried setting up a User Account for him. Each time I have tried my desktop disappears along with all my normal stuff.
Got over that by stepping the machine back to a previous restore point. However that obviously removes the User Account for my son.
Do not wish for my son to have Administrator access.
Advice would be most welcome. Thanks for reading this.
