My computer doesn't have an administrator account. I tried to add one in the registry, but got the "can't create value: error to writing registry". I also tried to change the permission, but got the "Unable to save permission changes on userlist. Access is denied." Can anyone help me? Thanks.
Administrator Account Your computer might have one that isn't visible. When you get to the logon screen (where you choose which user), hit control-alt-delete twice. Select the user name line and type Administrator. Leave the password blank and attempt to sign in.
If it is windows xp home edition press F8 at boot and that will bring up hidden administrator account
