Protect Administrator Account

[Albatrosi]

Hi,I just installed Windows Vista Ultimate Service Pack 1,and I have create
my Administrator Account with Password Protected,and a Standard User for my
family.
But my brother loged in as a Standard User,did something in REGEDIT and I
saw that he can delete or change password of my Administrator Account.
How can I protect my administrator account,how to prevent from being deleted?
Please help me!
Thanks,
Albatrosi

I am having the same problem, somebody please tell me how to fix it. My
person is going in, changing something so he can go to porn sites, and make
changes.

First: A limited account need to have permission from a administrator to use
regedit, services.msc, mmc.exe, etc.
He must have one of those passwords.

look he didn't type regedit to use it,he open regedit in other way,I don't
know how but he has opened it someway.
Can I protect my administrator somehow??
