In windows 7 you can start applications as admin by searching in the start menu and then pressing Ctrl+Shift+Enter.
Is a similar shortcut available for the Run Window (Win+R)?
This question has been asked before in 2010.
Unfortunately the result "no possible short-cut" applies even today. Run cannot elevate programs to admin level. It can only elevate the cmd via:
runas /user:admin "cmd"
The workaround is to manually set the program(s) to run as admin through the properties menu.
