RunasRob (free) lets a standard user run a program with admin privileges without...

...giving the standard user admin credentials.

It works . If you install the RunasRob service, you won't get UAC (User Account Control) prompts either .

You'll probably want to use the method specified in section "Quick start guide RunasRob with an encrypted file" using your admin account username and password, and option "Logon as another user."

I found another similar program called Game Launcher but I haven't gotten it to work yet.
