Your propsal solved the original problem, however my computer rebooted a second time without warning unexpectedly after putting in the command and rebooting.

Do I need to do something with the the configuration to avoid unexpected reboots later at other updates?

I have this exact problem on a freshly reloaded Windows 10 Pro

I rebooted tons of time, and also downloaded the windows10.0-kb4074588-x64_baac70613d5503dcd3e652ac24b7f432f3579eef

nothing works!  FIX IT M$
