Windows 10 pro, after anniversary update I can't use "runas administrator shortcut" anymore

Until now I used shortcut with "runas/user:ComputerName\Administrator /savecred "C:\Program Files (x86)\example.exe"

when I type a command in the cmd error 740 occurs:

C:\>"C:\Users\user\Favorites\Linki\runas.exe.lnk"
Attempting to start C:\Program Files (x86)\example.exe as user "ComputerName\Administrator" ...
RUNAS ERROR: Unable to run - C:\Program Files (x86)\example.exe
740: The requested operation requires elevation.

Does anyone know if this is an error or a deliberate action, and how I can achieve this functionality now?

Regards
