At this point, I get a blue Android setup screen asking me to choose the
language, but the Windows mouse doesn't yet put a cursor inside the Android
window except for the menus on the VM window.

So that's all I need to debug now.

The mouse is strange.

And, for some reason, the Guest Additions ISO won't work either.
C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso

But Android is up, a Google Play account was created, and I ran Android
software on Windows following these tutorials for installing Android 7
Nougat on Windows

Using those articles, I now have Android 7.1 running inside of Windows.

I've used Google Play to install Android software in the virtual machine,
and it seems to work.

The mouse is quirky, and I can't get the Guest Additions ISO to work but so
far those are the only glitches.
