Unknown user account

[VanEck]

touching on the admin account... like zencoder mentioned, do NOT delete the admin account... what you can do however is rename it. on all my systems, i open up the properties on the admin account, and 'cut' out the description. i then set a complex password (8-16 characters combine alpha-numerics and special characters). then i rename the entire account.

after that, create an account called 'administrator', pasting in the original description, and DISABLE this account. a quick and easy way to make your box just a bit more secure.

run the cmdprompt as admin and do:

C:\net user username /delete

I already tried the "net user <username> delete" command but in vain. It does show that the command was completed successfully but the account shows up again when i type "net user".
My brother was playing around with the computer and he did the same with the admin account and 2 diffrent account and they are now deleted. I still have one account with administrator privilages
As of now I have denied access to drive with systemroot to that weired account.
Now i cannot logon to default admin account. Anyway to get that back? also when i try to creat a new account with administratoras log-in name it doesn't allow me to do so saying such account is already present. any ideas?
