Microsoft has announced a new Azure capability known as automatic VM guest patching and designed to automatically apply patch Windows virtual machines against newly discovered vulnerabilities.

The new feature is now in Public Preview for Windows virtual machines on Azure and it is designed to help admins maintain their environments' security compliance by having Azure Virtual Machines (VM) automatically patched.
On VMs where it is enabled, patches will be installed within 30 days of the monthly Windows Update release, but only during off-peak hours.

On-demand patch assessments also available
"With automatic VM guest patching enabled, the VM is assessed periodically to determine the applicable patches for that VM," Microsoft explains.

"Updates classified as 'Critical' or 'Security' are automatically downloaded and applied on the VM during off-peak hours. Patch orchestration is managed by Azure and patches are applied following availability-first principles."

"To enable automatic VM guest patching, ensure that the property osProfile.windowsConfiguration.enableAutomaticUpdates is set to true in the VM template definition. This property can only be set when creating the VM," Microsoft says.
While in Public Preview, automatic VM guest patching only supports VMs created using a very short list of OS platform images — [...]

For this feature to work on a virtual machine, the VMs are required to have the Azure VM Agent installed, the Windows Update service running, must be able to access Windows Update endpoints, and must use Compute API version 2020-06-01 or higher.
