Issues with KB5034439 on Windows Server 2022? This is how you can temporarily hide this update.

Windows Server 2022 and Azure Stack HCI devices attempting to install the Windows Recovery Environment update (KB5034439) might see the following error: 0x80070643 - ERROR_INSTALL_FAILURE! This error is due to the size of the Recovery Environment's partition. If you'd like to wait for Microsoft to create a new release of this update, you can safely hide KB5034439 to prevent it from being offered over and over again.

Symptom	Next step
When you try to apply this update on a PC that has no recovery partition, the update is unsuccessful and you receive the error 0x80070643 ERROR_INSTALL_FAILURE.	You do not need this update if the PC does not have a recovery partition. In this case, the error can be safely ignored. We are working on a resolution and will provide an update in an upcoming release.
