How does @StartUpCommonDir identify the folder to which it points? On my system, it points to "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup", while for another user who is testing my script, it points to "C:\Users\{USERNAME}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup", even though the other directory also exists on his system. Can someone please explain the built-in logic that leads to these different results? Thanks in advance.
