Out-of-band update to address failure to install the May 2024 Windows security update

Microsoft has identified an issue wherein the May 2024 Windows security update might fail to install and has expedited a resolution. An Out-of-band (OOB) update has been released for the affected versions of Windows today, May 23, 2024, to address this issue. This issue is observed only in Windows 10 Enterprise and IoT LTSC 2019 editions and Windows Server 2019.

The OOB update released to address this issue is available on all usual release channels. This update is cumulative, so customers do not need to apply any previous update before installing it, as it supersedes all previous updates. This update does not contain any additional security updates from those available in the 5B update. Installation of this OOB will require a device restart. If you haven’t deployed the May 2024 security update yet, we recommend you apply this OOB update instead. For more information and instructions on how to install this update on your device, consult the below resources for your version of Windows:
