CPU Errors, Memory Errors, and BSOD after Windows Update (KB4056892)

Question

After installing  the "2018-01 Cumulative Update for Windows 10 Version 1709 for 64-based Systems (KB4056892)" the system log began to record the following CPU error every minute or less:

Reported by component: Processor Core

Error Source: Corrected Machine Check

Error Type: Internal parity error

Processor ID: 2

My computer (ThinkPad X1 Carbon gen 2) would crash (BSOD) intermittently with this error:

PAGE_FAULT_IN_NONPAGED_AREA

At first I thought the system might be damaged somehow, but I ran Intel CPU diagnostics, and the processor passed with flying colors. I did a system restore to the point just before the update was installed, and everything went back to normal. Is this a known issue? Are other people seeing these symptoms? Is there a fix in the works?

Answer 1

I recommend you block it until the next cumulative update is released. Many are reporting the same problem too and it looks like this update is buggy.

Is there an option or work around to block updates or hardware drivers that might cause problems?

Yes, Microsoft has released a KB update (KB3073930) that will let users block or hide Windows or driver updates.

You can download it at the following link:

https://support.microsoft.com/en-us/kb/3073930

or

http://download.microsoft.com/download/f/2/2/f2...

After downloading, launch it, click Next, wait while it detects pending Windows Updates.

Click the Hide Updates menu.

Scroll through the list then select then select the update. Check the box next to the update then click Next to confirm changes.

Answer 2

Yes, doing a System restore would have removed them.

If the System is stable now then you need not to worry about anything. If it is not, please let us know.
