Yep. This suggested a complicated trick. I found an easier one.
I just detect if the console title ends with "setup.exe"
(case-insensitive). If so it's new and can be hidden.

I added a patch to switch to the console subsystem and hide this concole
if it was a fresh new console. Otherwise, if called from a console or if
called with -h leave the console.
