I have a Windows 2012 server joined to a domain with UAC disabled by group policy. I'm logged on as a domain user with local admin rights.
I create a shortcut to a local HTML file, then I add that shortcut to C:\ProgramData\Microsoft\Windows\Start Menu\Programs. The shortcut appears in Start screen, but when I click on it, I get a dreadful message: "This app can't open - Internet Explorer cannot open while User Access Control is turned off". Of course IE works just fine on its own, and the same shortcut placed on desktop works fine as well.
I'm not sure if I want to know why this is happening (although clear explanations of the byzantine UAC system are always welcome), but I'd certainly like to know how to launch this sort of shortcuts from Start menu without having to enable UAC.
