If it wasn't obvious, I'm trying to find a solution, not assign blame.  Of
course it has "something to do with Cygwin", because I'm using it, and
Cygwin and WIndows are using a shared resource, the "HOME" variable.
Cygwin and Windows try to use it for different purposes.  There's nothing I
can do about the "Windows network profile".

Again, you took this as me trying to assign blame, which is pointless.

Yes, I meant 1809, and although I performed the upgrade manually, it would
have been done automatically in the near future if I hadn't, so there was
no choice there.

Yes, I've seen that, and considered my options there, but I don't think
that will address this situation.  The problem is the contents of the
"HOME" variable. It doesn't matter where my Cygwin HOME directory actually
resides.
