At the end of a long struggle, I am fine with the Broadcom driver v100.10.200.18.

My system has been running reliably for over 6 months now and I have been downloading all updates for windows as usual. Only once I needed to rollback the driver using the apple bootcamp.
Rather than restoring Windows to a previous image, I strongly suggest to do a repair installation for Bootcamp as it solves most of the problems. I can upload my whole bootcamp folder with the .exe if someone needs it.
Hope this is of help.
