I can't answer the question as posed, but I can offer a solution:
reverse the guest vs. host roles.  I've been running my few required
windows programs (industrial PLC tools, mostly) in Virtualbox hosted in
linux.  Since updates to my linux host *never* force an unattended
reboot, and rarely need a reboot anyways, the problem simply doesn't exist.

On top of that, I can run the windows VMs with no external network
connection, greatly reducing my malware exposure.

Seriously, friends don't let friends run Windows on bare metal.

HTH,
