If the user clicks the "No, others also use this key" button they get the following dialog

You are totally correct, confirmed with VSD 3.3.5.

I was curious: Similar to the kiosk/immutable feature of kconfig, gpgolconfig allows to flag values as immutable by appending a '!' to the value set in the registry. If autoencryptUntrusted is set to 0! via the registry then the checkbox should be disabled.

This ticket is only for ignoring the autoencryptUntrusted setting. For the gpgolconfig.exe part see T8090

@werner: Shall we backport the fix to the gpgme-1.24-branch or do we just add a patch to gpg4win's gpg4win-4-branch and/or vsd-3.3-branch?

I have verified (by locally applying the change to a Gpg4win 4 build) that ifdef'ing-out the above hack for Windows builds fixes the display issue.

To test in gpgol after the fix (see T7836: GpgOL: Both disable and prefer S/MIME does not work):

1. Make sure you have both secret openpgp and smime certs for ted (both split S/MIME keys)
2. Deactivate "Always show security approval dialog"
3. Enable S/MIME and activate "Prefer S/MIME"
4. Kill background processes and restart Outlook (just to be sure)
5. Send an encrypted/signed mail form and to ted => should be S/MIME encrypted
