gpg2 on a Windows 10 Pro 64 bit machine

[Jerry]

On a Windows 10 PRO 64 bit machine, when I run the following command:

	gpg2.exe --refresh-keys

I receive the following error message:

gpg: can't handle key algorithm 22
gpg: can't handle key algorithm 18

I am not sure what that is referring to. Also, there are numerous keys
listed as revoked or expired. Is there a anything I can run from the
command line that will automatically remove all revoked or expired keys?

This is the gpg2 info.

C:\WINDOWS\system32>gpg2.exe --version
gpg (GnuPG) 2.0.30 (Gpg4win 2.3.3)
libgcrypt 1.6.6
