who can tell me how to set password for it.

Thanks Mark, I may not ask clearly. Let me rephrase it. When I want to run
some applications, I have an option, which allows you to run as
administrator. Even though I have an account as an administrator, I still
need to run it as administrator. I want to set the password of this
administrator. How can I do it.

Thanks,

I have got a solution, run cmd as administrator, and issue "net user
administrator /active:yes" then I can create a new password for the
administrator. then I can issue "net user administrator /active:no" to hide
it on user account.
