Hello,
We are experiencing a similiar issue in our company, we tried everything possible except playing with the registry. The only know "fix" is to rollback the update. So the issue is that the network card stops working and the laptops are the ones having the most issues since the "Wi-Fi" button dissapears. After checking we saw that the "wlansvc" service is not running and we are not able to make it run (tried with normal users as well as admin user and local admin user). You can also use a "UTP dongle" to at least use a LAN cable on PCs or Laptops if you can't make the cable connection to work.
For now we have stopped the updates. If anyone has any more clues or solutions that would be most appreciated.
Regards,
Miloš
