Windows 7 - Add a password prompt to UAC?

I know this has been covered probably somewhere, but I can't find out how to add a password box to the UAC prompts so it asks for my password (or whoever's the account it is using privileges with). It did this sometimes in Vista, but I have Windows 7 (it came with this computer). unfortunately I found a tutorial on the forums, but it uses GPedit which Windows 7 Home Premium does not have. I would like to have the extra security by having to enter my password with UAC (I believe it does this in OS X too).

Here is a picture of the one on Mac OS X (Although I don't need it where you have to type the username)



Thanks!
