Such security updates were often cause for trouble by side effects in
the past. Even updates were taken back because of causing problems.

Maybe it is an anti-virus tool on the client or a "personal firewall";
the usual suspects.

Try it from a different client host. I bet it will confirm that it is
your Windows[tm] host after the update causing the timeouts.

Ok, I understand. Dovecot runs as it's own daemon, without a wrapper in
front or (x)inetd controlled.
