Windows OS security update block for some AMD based devices

Understandably tension are high, especially with this CPU fiasco going on. Then updating fiascos. Believe me, I'm only attempting to be helpful by pointing out some possibilities is all. If the kb doesn't install on some AMDs, that's the first I've heard of it. Happy that you pointed that out.

Also, I've heard that Macrium Reflect was having issues as well. Don't use it so can't help there.

So far as the term brick; It actually was introduced by means of unlocking cell phones with firmware, for here in the U.S. our phones were locked. When a firmware hack went bad it rendered the phone useless, so therefore called a brick. So the term is rather scary here.

I wasn't suggesting that you weren't trying to help - the whole purpose of this thread, in my mind is to discuss the fact that some PCs with AMD processors, are failing to boot after the application of KB4056892, which itself is supposed to help mitigate the effects of critical vulnerabilities of both Intel and AMD processors. So as far as AMD is concerned, the cure is worse than the disease!

Regarding Macrium Reflect: I'm using Free Edition (64 Bit) version 5.2 which is an old version that works. I've imaged and restored several PCs both Intel and AMD, since Windows 7 days. It ain't broke, and I ain't fixing it!

Regarding the term "brick" -point taken but I did say "My PC isn't bricked - it just refuses to boot after KB4056892 is installed"
As you imply, this whole episode is frustrating us all especially as it's not entirely clear whom to blame!

This MS article may be worth keeping an eye on.

I thought Microsoft had pulled KB4056892 from my PC, but noticed this morning that it's wanting to install on my computer. I've tried this update about 15 times now and it won't install. Gets to 99% and will stop.
I am running an AMD computer. Just wondering if I should download KB4073290 and try to install on my computer. My computer is not an older AMD. I've had this machine 4 Yrs? Would it be OK to try to install since the KB4056892 is waiting for me to install it?

It's probably wanting to install KB4056892 because it's already downloaded it.

I would try running the Windows Update Mini Tool,

Use it to block KB4056892 , THEN run the manual installation of KB4073290

Here is what I did this very afternoon I didn't need to use the Mini Tool because I'd previously restored Windows to an earlier version so i KNEW nothing was "lurking"

Assuming it works OK, after that, go and Clean the System files from your C: Drive which should hopefully get rid of part-installed updates. Option 1, Item 5 in this thread
