Secure Boot: Microsoft Windows Production PCA 2011 expires
WindowsWindows Server
- Who is affected
- Windows devices whose boot manager still relies on the 2011 Windows Production PCA. The replacement is Windows UEFI CA 2023, which signs the Windows boot loader.
- What to do
- Confirm devices report the Windows UEFI CA 2023 certificate in the Secure Boot database.
- Expect one extra restart on some devices when the Secure Boot certificate update applies.
- Refresh boot media, PXE images and VM templates so they boot with the new certificate chain.
