Windows 7: elevated task scheduler shortcut for standard user

I logged into a administrator group account and made a shortcut and scheduled a program with task scheduler as pointed out here.

Now I have 3 Standard accounts, 2 Administrator group accounts and a Administrator Account. When I place the shortcut on the standard users desktop, it doesn't work.



I notice at the page that I mentioned, it says that you must be logged into a Administrator account for this to work, but I have done this before and it worked.

Has an update been released that stops this working?. It is a real pain. Another person on here mentioned that it may be done by making it a service and the service provides the privileged access when it needs it. How is this done?
