Prepare your servers for Secure Boot certificate updates
The original Secure Boot certificates introduced in 2011 are approaching the end of their planned lifecycle, with expirations beginning in late June 2026.
Following our announcement from last week, we’ve now released the media for Windows Server 2012 R2 Update on the Volume License Service Center (VLSC) today. Additionally, we wanted to create awareness of an issue with the Windows Server 2012 R2 Update VSLC/MSDN media that manifests under very specific configuration settings. Most of you should see no impact whatsoever. For the small number of who might encounter this issue, we have issued additional information and workaround guidance here.
