Known issues

While KB5008206 is free of any bugs or known issues as per the rolled-out info, there are a couple of concerns with KB5008218. Let’s take a look at those and check out the potential workarounds for the same.

Issue 1:

This is a preexisting issue whereby you may encounter the message 0x800f0982PSFX_E_MATCHING_COMPONENT_NOT_FOUND on devices with Asian language packs after certain recent updates.


A temporary workaround that seems to be working for this particular issue is uninstalling and then re-installing the language packs you have recently added.

Also, you can check and confirm the installation of the April 2019 Cumulative Update. Make sure to install it if not already installed.

Lastly yet another workaround suggested in this context is to Reset your PC while keeping files. Do this only if nothing else works. By Resetting the PC, you can remove third-party apps and programs and reset all the settings, etc. to revert to a clear state. You can navigate to Settings > Recovery > Get started > Reset this PC > Keep my file to do the same.

Issue 2:

This issue is also previously known. Following the installation of KB5001342 or later patches, the Cluster Service might face trouble starting. The whole thing could result in an error Cluster Network Driver is not found.


A temporary workaround for this issue is to restart the device after about 20 minutes of installation.

Issue 3:

It has been noticed that post the installation of April 22, 2021, or later updates, a problem is consistently affecting the versions of Windows Server being used as a Key Management Services host. To be more specific, the client devices running on Windows 10 Enterprise LTSC 2016 and Windows 10 Enterprise LTSC 2019 might fail to activate. This issue only occurs when using a new Customer Support Volume License Key (CSVLK).

This particular issue is not known to affect the activation of any other edition or version of Windows.

The aforementioned affected devices that are attempting to activate by this issue might receive the error, “Error: 0xC004F074. The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information.”

To get a bit more idea of the error, open Event Viewer on the client device which has failed activation. Navigate to Windows Logs > Application. If you see only event ID 12288 and not a corresponding event ID 12289, it could indicate one of the following:

  • The KMS client couldn’t reach the KMS host.
  • There was no response from the KMS host.
  • No response was received by the client.


The developers are currently working on a resolution and there is no known workaround for the same. We can expect a resolution in one of the upcoming releases.
