Known issues

There are no known issues in KB5009545. However, certain concerns are observed to be occurring still with patch KB5009557. Let’s take a look at the same:

Issue 1:

Ever since the patch KB4493509 was rolled out and installed, certain devices with some Asian language packs installed may come across some error messages often. It  may look something like “0x800f0982 – PSFX_E_MATCHING_COMPONENT_NOT_FOUND.”


  • Try uninstalling and reinstalling any of the language packs that you recently got.
  • See if you have the April 2019 cumulative update. If not, search for any pending updates and install the same.
  • If neither of the above workaround fixes the problem, you might have to reset the PC. You can Reset your system without losing your personal files by going to – Windows Settings > Updates & Security > Recovery > Reset This PC > Get started > Keep my files. You can simply follow the on-screen instructions afterward.
Issue 2:

This issue has been around ever since the release of April 22, 2021 updates or later ones. It is observed that after the installation of the said patches, an error occurs that affects versions of Windows Server that are in use as a Key Management Services host. Client devices running on Windows 10 Enterprise LTSC 2016 and Windows 10 Enterprise LTSC 2019 might not activate. It is noted that this issue only occurs when users are making use of a new Customer Support Volume License Key (CSVLK). Also, this error isn’t observed to be affecting the activation of any other Windows editions or versions.

The error found in the said scenario is, “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.”

No workaround is available for the error as of now. The developers are attempting to work on the same and a resolution should be available in one of the upcoming patches.

Issue 3:

Ever since installing the update KB5001342 or some of the later ones, the Cluster Service might fail to start with the reason that “a Cluster Network Driver is not found”.


The problem is noted to be occurring due to an update to the PnP class drivers used by this service.  When you face any such issues, wait for some time. After about half an hour, you should be able to restart your device and not encounter this issue.
