I tried to use the wushowhide.diagcab on two machines and the update still installs and asks for a restart..
The best I have found is to make sure your active time is 18 hours long to minimize the hitler forced install ..
and then during that active time when all the new updates are downloaded and ready to go click install
and let them all install .. and then click on View installed update historyand on that page click on Uninstall updates at the top of
the page and find KB4056892 and uninstall it and then do your restart ..
I HATE FORCED UPDATES !! ..
MS should be held liable or loss of data with updates in this mode ..
There was nothing wrong with the way windows 7 had it where we could choose to not install a bad update
until it got fixed ..
Speaking of which .. When is KB4056892 getting fixed ...
My son, a senior IT guy, says that if windows defender is up to date, then the odds of someone getting into your machine
in a way that is required to execute meltdown or spectre is extremely minimal.
Which beats having your PC bricked by a force update.
In my case I COULD NOT recover .. even with a backup ..
Though I could still dock the drive and remove any needed data.
