I just bought a new hp laptop for my daughter. After booting the machine and creating backup systems disks, I went to User Accounts and setup a new account for myself with Administrator rights. I then changed my daughter's account to a Standard User.

Next, I booted to my new account. When I went to confirm the setup, it said I was a Standard user as well as my daughter's account. There are now no Administrators and I can't load any software. Please help!

I would just reload from the backup disks. This time create your account first and once you've logged on you can create your daughter's account as a standard user without affecting your account.

Pls use any recovery software. Boot again and recover your Account first. I will be hope u can recover your daughter account.
