How to change back to only Admin (read plz)

[NinjaKitty]

So, my brother and his friend were dicks and messed w/ my computer. I set up a password on my computer for a purpose.
So; my bro somehow got past my computer password (was secure pw) and then used my account to create another user account. He made that one the main user admin and changed mine to standard. I changed mine back to admin, but I want to delete the account he created and have only my account back w/ all the power (main admin). I'm not able delete the main account he created and I dont want to delete mine because of all the settings on it..

so; how do I delete the account my brother created as admin and change my account back to main admin? I'm not able to delete the account my brother created because I think its the main one or something, I can only delete my original one that he changed.
Thanks

You need to demote him to a normal user first.

^ thanks, but I'm not able to. It won't let me demote him.

Hello NinjaKitty, and welcome to Seven Forums.

Did he use the built-in "Administrator" account? The name of the user account would be "Administrator" if so.

If he did, then you could change the password on the account, and disable it.

Hope this helps,

Have you tried searching for "cmd" in the start menu and run as administrator, then:

Type

net user [I]"username"[/I] /delete

??

^may you type an example : )?

Sorry about that lol. Anyway here's a more detailed explanation:

1.) First, you need to open an elevated command prompt. Brink explains it best here http://www.sevenforums.com/tutorials/783-elevated-command-prompt.html

2.) When the command prompt appears, type:

net user [I]"username"[/I] /delete

Where username is the name of the account you want to delete. The quotation marks are there in case it has spaces. Otherwise, it won't work.

Let us know if it works or of any error codes that might pop up.

P.S.
I ask you to reconsider Brink's advice on Built-in administrator accounts, as they are usually the only ones that cannot be demoted or renamed.
