How do I disable standard user from changing password?

[shood]

I'm using Vista Home Premium.

I know that there is no Local Users and Groups folder in Computer Management.

I am the administrator, and I want to disable a standard user's ability to change their password. In other words, I want to have access to this user's account when I need--I want them to be able to be password protected, but I don't want them to be able to change this password once they have set it up. This seems to be possible to do in other versions of Vista, but not Vista Home Basic or Vista Home Premium.

Still, it seems incredible to me that there is not a way to do this in these versions of Vista (think a mom who needs access to her kid's account...).

So--How do I do this without a Local Users and Groups folder?? Or in other words, how do I work around that?

it is not real obvious.

start in a elevated command window
net user ?

I.e. net user 'account' name has options to 'allow the user to change
password'
