Microsoft’s Virtual Machine Mishap: Emergency Update Saves the Day!

Microsoft’s emergency update fixes a bug preventing Azure VMs from launching when Trusted Launch is off and VBS is on. Impacted Windows Server 2025 and Windows 11 24H2 users should install this out-of-band update, not July’s Patch Tuesday. The key? Use Trusted Launch to avoid the bug or check if your VM is “Standard”.

Hot Take:

Microsoft might have accidentally created the world’s first virtual Houdini act, where Azure VMs just disappeared into thin air! Fear not, though—Microsoft has pulled a rabbit out of its hat with an emergency update to summon those elusive VMs back to life. So, admins, get your wands—or rather, your keyboards—ready for some magical patchwork.

Key Points:

  • Microsoft’s emergency update resolves a bug preventing Azure VMs from starting.
  • Bug impacts Windows Server 2025 and Windows 11 24H2.
  • The culprit: a secure kernel initialization issue when VBS is enabled.
  • Admins should replace July’s Patch Tuesday update with the new fix.
  • Trusted Launch feature can prevent future VM vanishing acts.
