I have a Surface Pro 3 and KB4551762 worked great for a week. I installed it on 3/13, I believe, and had no issues until today 3/22 when my computer woke from sleep it could not find the network adapter. I tried the troubleshooter and I even tried navigating to the folder where the adapter should show up and it was completely gone. I restarted a few times to see if that would help (sometimes it does this randomly and restarting fixes it), but nope.
I finally just uninstalled the KB4551762 update and when my Surface Pro restarted, everything was working again.
