Known issues in KB5025230
A couple of issues have been reported post-deployment of KB5025230 on Windows Server 2022. You can read more about the issues on Microsoft’s release notes for KB5025230. A brief listing of the issues is stated hereunder.
- After installing this update on guest virtual machines (VMs) running Windows Server 2022 on some versions of VMware ESXi, Windows Server 2022 might not start up. Only Windows Server 2022 VMs with Secure Boot enabled are affected by this issue. Affected versions of VMware ESXi are versions vSphere ESXi 7.0.x and below.
- Updates released February 14, 2023 or later might not be offered from some Windows Server Update Services (WSUS) servers to Windows 11, version 22H2. The updates will download to the WSUS server but might not propagate further to client devices. Affected WSUS servers are only those running Windows Server 2022 which have been upgraded from Windows Server 2016 or Windows Server 2019.
We recommend checking out the solutions offered for both issues by Microsoft.
