Yeah that’s what I just saw, we can’t access it…
So my startup disk is C:
I was able to move the Launcher with the Xbox app, (and not with the Windows option)
In my image you can see where the Launcher is installed, and the 2 arrow indicates the option (modify the drive) that’s what I did…
Yes it is not really necessary to move it (for 2GB)
On the other hand, I don’t believe that TenPatrol said that it was possible to move the Launcher 
“It seems to me that he is saying don’t, especially, not move it”
(Sorry it’s in French)
(edit) Hmm, maybe I misunderstood your message,
Perhaps you only spoke for the Official and community file? and not the Launcher
