I see a lot of people are trying to do regedit, disabling scheduled tasks and even reinstalling drivers.
I took a different approach to this, I'm fortunate enough to have a decent firewall that allows me to control which ports are accessible to specific IP addresses.
What I did to prevent this shitty microshaft update to hit my servers was by blocking all external incoming and outgoing ports on the fixed IP addresses of my mining rigs EXCEPT the specific port the mining software requires to connect to the mining pool for Ethermine it's port 4444).

I'm using a Watch Guard firewall, it's an expensive firewall but there are other manufacturers that provide similar features.
I have never tested this solution using the Windows Firewall, but I imagine that M$ is smart enough to get around their own built-in firewall.
The surest way is to block all incoming and outgoing traffic on a network level and ONLY allow specific ports needed for mining and remote management.

If you already got hit by this dumb update, I would highly suggest restoring an earlier backup of your windows OS if you have one.
If you do not have a backup prior of the windows update, do what you can by uninstalling the update, removing scheduled tasks in the windows update and updateOrcastrator directory and deleting the update files from the System32 directory.
