PSA: I have converted 3 Windows 10-S laptops to Windows 10 Home (only one gotcha)

I have converted 3 Windows 10-S laptops to Windows 10 Home
where there is only one main gotcha, AFAIK, which is that you _must_ first
create (or log into) a Microsoft account BEFORE you can convert Windows
10-S to Windows 10 Home (AFAICT).

Even if you specifically don't initially connect to the net, you _still_
(eventually) need to create that Microsoft account, where you can use an
old account or create a new one and then delete it.

If you let Microsoft _create_ a new account, it will take a month (elapsed
time) to delete that newly created account, AFACR.

To convert, as usual with Microsoft, there are a ton of entrances to the
button, where my suggestion, for efficiency, is simply to download _any_
installer (e.g., Firefox installers work just fine) and in the process of
trying to install that program, the dialog to convert from Windows 10 S to
Windows 10 Home comes up naturally - so you don't even have to search for
the command.

Just install the first thing you normally install on a new system, which,
for me, is Firefox - which worked like a charm.

There may be other gotchas but those are the only ones I know of so far.
