Windows 7: Not able to delete a user account

Hi,
i'm the admin of my laptop. recently i created a standard acc for my friends to access my laptop. but now that acc is changed to admin and now i'm not able to change its type or delete that acc as if it has some high privilege. i try doing the same using the built in admin acc and result is same. when i tried the following two commands in cmd the following response is obtained, here 'home' is the acc i created for my friends

C:\Windows\System32>net localgroup administrators home /delete
System error 1377 has occurred.

The specified account name is not a member of the group.


C:\Windows\System32>net localgroup administrators home /add
System error 1378 has occurred.

The specified account name is already a member of the group.

the acc home is there at the same time its not there.

then i tried 'control userpasswords2' in run and change the group membership of home but still it wont change and also does not give any error.

then i tried mmc to access local user and groups and tried deleting home from admin group but it results in the error shown in the image



following image shows that home is not an in-built admin acc.



here HP is my acc and bee is just a temporary standard acc i made temporarily.
here home acc is my problem.

now when i try deleting this acc from mmc the followng error comes




please i need help. how can i delete this acc??

Hi and welcome to the forum
Perhaps this will help you:
Default User Accounts and Groups

hi mitchelle,
thanks for ur help but can u be more specific of what should i do. Reading all that gives me circles in ma head.
thank you

Link provided by mitchelle is very useful. Still you can try this

open command prompt as administrator then enter the following.

net user administrator /active:no

log off and it should be gone.

ELSE, You can try this link as well.

Delete a user account

When you create a Group Windows automatically creates an Admin Account for that group. You cannot delete that admin account as then there would be no way to log into that group. Careful reading of the link I sent you explains this better. You can delete the whole Group if you wish see here:
User Accounts - Add or Remove from Groups

But that is to disable the Hidden Admin account which should never be left enabled!

Thank you Mitchelle,
but as u can see in my first post when i try to delete the account the response is same
i'll attach the image again for your reference




its like the acc "home" is a ghost. it is present at the same time its not present.
Thank you

I will have to leave you to others as apart from generalisation I cannot go further as my Version of Windows 7 does not support groups. You might though have a problem with your installation. Did your copy of Windows come pre installed as I would expect you PC to have the Home version pre installed? If not where did your copy of Ultimate come from?
