After installing windows update KB5065789 routes that are in Split Include are not in the windows routing table. It works if I add the route manually. Removed the windows update and its working again.

Hi,

Do you think that it's a Mikrotik related problem?

Hi, definitely not a Mikrotik problem but I wanted a confirmation from someone else and a heads up for others that have the same problem.

Ummm... good to know.

Hi,

I confirm the issue, we are stuck with all our customers / users.
No workaround found but adding static routes or downgrading Windows to the previous patch level.

Thank you Microsoft…

There was a suggestion for making a separate category for general networking questions. Would be useful to discuss stuff like that. No response from MikroTik...
