Vista - hidden accts / logon / not show / still one user pic

Searched and saw couple related posts, but not quite this:

Want to create new administrator account, same as other workgroup PC's,
(mostly XP Pro SP2; w/ no such problem), to help file sharing, plus also
other admin logon, separate profile. May or may not also enable real
"Administrator", but need new one, and would have same problems here, anyway.

I do not want the new admin account to show on the logon welcome screen.

Want very much, to have the one main user's "user picture" displayed at
logon, not window + screen grayed-out.

Hope to do all without any ctrl-alt-del to begin, but "regular" happy Vista
welcome/logon screen on boot.

Yes, I understand Vista â‰* XP, where c+a+d, you can do this easily.

Thanks!

Bump.

Should I re-phrase the question; or, is more info needed?
