If you'd done a little research, you might have found this:

Yes, it is from the official launcher. I don't see why you'd expect
Microsoft to go to the effort of building their own launcher when it
can be available for every Python user.

How relevant is this?

I remember the days when OS/2 was the big target, and Microsoft was
the greatest anti-OS/2 voice out there. Does that affect the way I use
tools today? Is it even slightly relevant?

I remember when Intel had floating-point division issues in their
FPUs. Do I tell people "don't do floating-point math on Intel
processors"? Is it relevant?
