Then your easiest route is to use the same key unless you need to keep your
identity on each machine separate. But if that was the case, you wouldn't be
using the same email address.

Just copy the keyring files.

Don't use C:\GnuPG. Accept the GnuPG installer defaults.

Yes, but then the recipients of email from each machine would have to keep track
of two keys. They also would not know whether to use machine A's or machine B's
key to send you an encrypted message.

Quite possible. I use the same keys on about a dozen machines running various
operating systems.

You would copy your keyring files (*.gpg) and gpg.conf from the GnuPG home
directory on the first machine to the GnuPG home directory on the second machine.

You're Welcome, but stick with just the one email address when sending, OK?
