Windows 10 2004/20H2: Update fails due to Intel Management Engine

[German]There are reports, that Intel Management Engine is causing issues during update installation in Windows 10 version 2004 / 20H2? A German blog reader pointed me to this issue, because updates are dropping a bluescreen PAGE_FAULT_IN_NONPAGED_AREA (update error 0x800F0845) during installs on machines with certain chipsets. The cause seems to be the Intel Management Engine.


Updates fail with BSOD

German blog reader Manuel W. contacted me in early February 2021 via email and shared his observations. He has the problem under a Windows 10 version 2004 that he can no longer install updates since September 2020. He wrote:

Unfortunately, I have been having problems making Windows 10 2004 build 19041.450 updates since September 2020. I was able to install the last cumulative update for Windows 10 in August 2020. It ends every time with a bluescreen PAGE_FAULT_IN_NONPAGED_AREA (update error 0x800F0845).

Updates like .Net Framework or (at that time also Adobe Flash) can still be installed without problems.

Manuel mentioned that he is not an expert to fully evaluate a bluescreen. But his knowledge is enough to narrow down the source of the BSOD. In addition he writes:

My hardware is ok. I looked at the dumb with WinDBG and it might be due to the Intel Management Engine (TeeDriverW8x64) or the driver.

His various repair options, which he carried out, unfortunately remained without success. In the meantime Manuel has found some articles about this problem in the net, so he is not alone with the error. Manuel wrote about this:

It mainly affects z97/h97 chipsets, I myself still own a z97 from MSI with an Intel i7 4790k. Installing the Intel management driver downgrade or update also ends with the same BSOD. One could almost believe that the access is denied.

Uninstalling the August 2020 update and trying to update directly to a newer version doesn’t work either.

Manuel writes that the cumulative update from August 2020, on the other hand, can be installed again without any problems. Exciting question would be if this is an isolated case?

More cases found

Manuel came across a thread on the Evga forum. A user with Windows 10 20H2 ran into a similar problem describes it like this:


Z97 Classified and Win 10 20H2 update

Hello, I need some help with my Z97 board, I run it with Corsair 16 gig RAM kit which is to 8 gig sticks, and I’ve had no issues with it with my i7 until now.

When it tries to do the monthly November incremental, and/or does the feature update to 20H2, the update begins and installs and after 30% when the computer restarts, it begins the reboot sequence and then I get a blue screen with a page fault error. It would do the typical two-boot try and then do the automatic repair and uninstall the update and I would be back to my desktop.

The log showed that I put on 10 forums that it was something to do with Intel management engine, but I also uninstalled that and retried, same thing. […]

This user describes his problems in detail in the thread and names the Intel Management Engine as the cause. According to the user, deactivating and then reactivating it in the device manager also ends in a BSOD. For some users who describe the problem on the web, a reinstallation of Windows 10 does not work either. Manuel states that this is also the case for him.

On Microsoft Answers there is the thread PAGE_FAULT_IN_NONPAGED_AREA after installing KB4571756, where one user describes the error on Windows 10 version 2004 in connection with the update KB4571756 from September 8, 2020. A dump shown there refers to AV_R_INVALID_TeeDriverW8x64 as the cause of the BlueScreen error.

There is another reference in the Tens forum within the thread FAILED install: September 8, 2020—KB4571756.  I didn’t search further, Manuel writes that there are more posts on the internet. To this Manuel adds:

There are other contributions on the net. But whether these are sufficient to inform Microsoft that there are problems here, too, I almost doubt.
doubt – or [that] manufacturers provide new drivers or firmwares for older hardware.

I’m beginning to wonder if this isn’t related to the recent problems with Lenovo devices, as there were/are problems with the Intel Management Engine here as well, among other things.

Do you are facing this issue too? Any other insights or a solution? I will try to forward this to Microsoft´s support.
