Windows 10: Update KB5001716 is installed secretly; throws error 0x80070643

Windows[German]I came across information in various places today that Microsoft is (secretly) installing an update KB5001716 on Windows 10. It is a "preparatory update" so that the systems can switch to Windows 11. However, some users are receiving the installation error 0x80070643 in the installation history. Here is a brief overview of the situation.

A reader tip in the morning

During today's "round trip through the web", I already noticed that there was trouble with the KB5001716 update for Windows 10. So I was able to classify the email from German blog reader Hans very well. Hans wrote me the following under the subject "Failed updates":

Hello Günter !

Now I have 2 corpses on Windows Update.

Every day I search for definition updates for Windows Defender on Windows Update. During the search
always the update KB5034441, which failed with the error message 0x80070643.

An update KB5001716 was added a few days ago. This also fails with the error message 0x80070643. So I have 2 skeletons in the closet.

I have shortened the rest of his email. In a second mail with the subject "KB5001716" he added the following:

Hello Günter!

I have just noticed that KB5001716 is reported as installed in my control panel. Now I don't understand why this thing is offered to me again and again on Windows Update.

Of course, it's not ideal when an update is installed automatically and then fails with an error.

What is Update KB5001716 for

Update KB5001716 is the former "Compatibility Update", now more accurately referred to as the "Update for Windows Update Service Components". It is available for the following Windows 10 systems:

  • Windows 10, Version 22H2
  • Windows 10, Version 21H2
  • Windows 10, Version 21H1
  • Windows 10, Version 20H2
  • Windows 10, Version 2004
  • Windows 10, Version 1909
  • Windows 10, Version 1903
  • Windows 10, Version 1809

The description states that after installing the update, Windows may attempt to download and install feature updates on the device. This applies if the support of the currently installed Windows version is approaching the end of support. For most systems, however, this is more likely to result in an upgrade to Windows 11 if this platform is supported by the hardware. For many systems, the update no longer really makes sense.

After installing this update, Windows may periodically display a notification informing the user of issues that may prevent Windows Update from keeping the device up to date and protecting against current threats, according to Microsoft. For example, a notification may appear informing users that the device is currently running a version of Windows that has reached the end of its support lifecycle, or that the device does not meet the minimum hardware requirements for the currently installed version of Windows.

Issues reported

The colleagues from neowin.net also report on this update in the current article Microsoft quietly installing KB5001716 so you can update to Windows 11 or newer Windows 10 and confirm Hans' observations above that an error is also thrown for some users. There is this Neowin.net article with some hints on how to resolve the error.

    Hi Gunter:

    This Fact just happened to me in one of my VMs. I followed the instructions of the Neowin.net article to uninstall the update KB5001716 and rerun Windows Update do install update again. The install occurs normally, but the Windows Update always try to reinstall update again and this way the error repeat itself. I think that this is a bug that only MS can solve.

      or you just use wushowhide.diagcab to hide/block the KB5001716 update from installing

      I'm giving wushowhide.diagcab, wumgr & windows update minitool a neat workout to hide & block some of these recent & problematic MS updates.
