Event details
Will Microsoft and/or Broadcom provide a solution to automatically update ESXi VMs with missing KEK/PK?
The solution from the article https://knowledge.broadcom.com/external/article/421593/missing-microsoft-corporation-kek-ca-202.html is unfortunately no longer available (upgrading the hardware version and deleting/renaming the .nvram file).
This article https://knowledge.broadcom.com/external/article?articleNumber=423893 states:
"There is no automated resolution available at this time. In coordination with Microsoft, Broadcom Engineering Team is actively working towards implementing an automated solution in a future release to update the Platform Key (PK) on the affected VMs, which will facilitate the certificate rollout as outlined in the Microsoft Guideline."

Hello IT_SystemEngineer​ , As you mentioned, we are coordinating with Broadcom to bring support in Windows to update KEK on the ESXI VMs. If new VMs are created on latest versions on ESXI, VMs get created with new certificates. For pre-existing VMs, Microsoft is coordinating with Broadcom and will be enabled in the future update.
