Hello. Today I've been having a problem trying to open an application as administrator in a standard user account. Well, finally I achieved it and I really don't know why isn't this solution in your tutorial. I've created a shortcut access using this as adress:
runas /user/(pcname)\administratoraccount /savecred "Route to the program"
Obviously, substitute (pcname), administratoraccount and route to the program for the ones you require. Then, when you double click the icon, a wild console appears and you type the password to the administrator account. Thanks to /savecred command, the password is always remembered and the next time you want to open it, the application directly starts. I've checked it and no UAC pops-up, it works perfectly fine in the five or six laptops here in the office.
PS:Sorry, if there's something wrong with spelling, syntax or grammar. English is not my native language.
