I deleted my account off my comp so that there would only be an administrator profile. the guest account is turned off. when i restarted my comp, it still wants me to login under the old name. so ive basically locked myself out of my own comp. PLEASE i need help.

Home or Pro?

Pro: hit Ctrl>Alt>Delete thwice at the boot screen then enter Adnibstrator and password (if relavent).

Home: Try booting into Safe Mode by repeatedly tapping the F8 key after your BIOS POST but before Windows starts. Here you should see the choice of Administrator.

Either way you should not use the built in Admin account as a daily user.

Create a new admin account.
