Users have complained that the updates released by Microsoft last week for the Spectre and Meltdown vulnerabilities cause Windows to break down on some computers with AMD processors.
Several individuals whose computers rely on AMD processors, particularly older Athlon models, say they are unable to start Windows 10 after installing KB4056892, an update released by Microsoft in response to the disclosure of serious flaws affecting Intel, AMD and ARM processors.
The security holes have been dubbed Spectre and Meltdown and they allow malicious applications to bypass memory isolation mechanisms and access passwords, photos, documents, emails, and other sensitive information. Both local and remote exploitation are possible.
Users have reported that after installing Microsoft’s update the operating system freezes during boot when the Windows logo is displayed. Some users claimed to have had problems reverting to a previous state, and those who did manage to do it warned that the automatic update feature needs to quickly be disabled to prevent the update from being reinstalled.
While a majority of the affected users appear to have older AMD Athlon processors, some devices with AMD Turion CPUs also appear to have been hit.
Microsoft has not shared any information regarding this issue. A Microsoft spokesperson told SecurityWeek that the company is aware of the reports and is investigating.

So is my Texas Instruments TI-99/4A. I'm having a grand evening playing Hunt The Wumpus.
Actually .stock C64 did 1200 baud and third party upgrades went to 33.6k.
My MS updates used to take 12 hours .
Industry should have stayed with the 68000 derivatives.
no idea.. waiting for guidance from our techheads...
Are you running Windows 10 Pro?
If so, click Start, Settings (the gear icon), Updates & Security, Advanced Options (under Update Settings), turn on Pause Updates.
You might want to give your basic approach to recovery in case it happens to someone here.
Brilliant plan by Microsquish - if it won’t boot no one can get into it!
There is a theoretical possibility of it being used via javascript. Turn off javascript in the browser, problem solved. Update the browser, problem solved
I have completely unpatched Windows. Not a problem.
I don’t know if you have Windows 10. You are probably stuck with them. I use 8.1 and goto control panel, system and security, system, Windows Update (lower left), Change Settings, Never check for updates.
That is not a given. More than likely a part of the patch failed to take into account a architectural difference on the AMD CPUs, which is ironic since AMD64 is defined by AMD, not Intel.
MS rushed out a patch for their Intel compute farm customers, is the more likely issue.
Probably the bug in the code was not revealed on Intel is more likely. Or it was tested on AMD, but due to risk to large customers, MS decided their Intel customers with vast compute farms were more important in the immediate.
Not a conspiracy, but follows business logic.
Though one would hope us other paying customers will get a AMD clean fix soon.
...and not be force fed the bad fix in the interim.
No way you could read 3300 characters per second without either a dma serial uart, or clock bump.
In my case, the machine recovered on its own. Here’s what I observed:
Happened to go past the room where that machine is located, noticed that the Window startup screen was effectively frozen - no spinning dots indicating startup, just the Windows logo on the screen. Moved the mouse, but got no cursor. Hit reset and initiated reboot. Got to the same point and froze again.
Did another reset. With Windows 10, a couple of failed boot attempts will summon up an automatic repair routine that checks and attempts to correct startup problems. In this case, it detected the failed update and undid the changes made by the update.
Had this failed, I would have restored a backup image of an earlier build to my hard drive using Macrium Reflect Free.
From https://pureinfotech.com/kb4056892-windows-10-build-16299-192/: The update for Windows 10 version 1709 is described as KB4056892 and bumps the version number to build 16299.192. While in version 1703 (Creators Update) the patch is described as KB4056891, KB4056890 for version 1609 (Anniversary Update), KB4056888 for version 1511 (November Update), and KB4056893 for Windows 10 version 1507 (Initial Release).
Thank you. Very good to know.
Why would they test it?
Isn't that what their customers are for???
windows 7 pro
Windows 7 on both my PCs - HP and Dell . Both 64 bit .
They are pestering me and I put them off until “tomorrow.”
Glad I saw this. I will delay again ‘n again.
Actually, IIRC, in 7, there's an "action center" in the icon tray in your taskbar. There should be a Windows Update button there somewhere. Choose the setting with the red X.
