While running gpg4win uninstaller there comes up a "gpg-connect-agent.exe"
command window for some seconds. Please prevent this window.
Tested with gpg4win 2.2.6
(Original reported from https://roundup.kolab.org/issue4465)
Edit: Changed the title to "Gpg4win does not kill all agents on update" because the Console windows are gone but the problem remains that gpg-agent is not fully / properly killed on update.
