I was not able to verify which guests needed this file and so it was supplied to all, as it seemed to have no ill effects on the server versions of Windows I was testing with.

this looks like a piece of outdated folklore to me. At least all versions from
Windows 7 SP1 onwards boot from CD into a dialog reading like
"press a key to boot from CD" and fail over to the hard disk if you don't.
So the installation continues as it should.

I installed Windows 7 and 10 numerous times and never had to use that
"null.iso" hack.
