Thanks for letting me know. I installed the 2017.1 version but I don't see the new keys available under "Public Key Policies" yet. I confirmed 5.4.1.439 is the installed version of the Group Policy Management Editor Exenstion and the ADUC exension. Is there another component I need to see the new keys?
The only ones that show are Do not Allow private key to be extractable & Store Private and public key in keychain only.
