Thanks Paul for the great response. It's much clearer now.
With Workstation 15 and my Windows 11 guest there was no encryption at all. But when I start this guest under Workstation 17 it immediately comes up with a progress bar saying encrypting.
I understand now why this is happening, but what is the password as nothing is ever entered and nothing is asked? It just starts encrypting.
Thanks again.
Greg
EDIT:
It is strange that Workstation 17 goes ahead and encrypts the W11 guest and you have no idea what the password is. Settings show this after the encryption. There's nothing in Credential Manager either.
