Hey Peter, :)
Correct, but it would be a good idea to install this update if you have an AMD processor no matted if you had the issue.
KB4056894 did cause no reboot to my AMD pc (had to do image rebuild). Since I'm now gun shy I'm trying to completely understand before proceeding with this.
Should I install just this update KB4073578 and not KB4056897 or KB4056894? Or should I follow Ieherus2000's above procedure, since I'm not sure his pc was crashed like mine?
Using what leherus2000 posted above should work fine.
Just be sure not to restart the computer until after this KB4073578 update had been installed though.
My PC did not crash.
I didn't attempt to install the original problematic update (KB4056897 OR KB4056894).
It may not have been vulnerable to the issue (I'm using AMD Phenom II CPUs).
I download the monthly (Security-Only) updates, but I usually wait (sometimes up to a month) to install them.
In this case, reports of issues started after only a couple of days, so I waited for new fixes/updates to appear.
Good to hear that it worked for you. :)
