Microsoft has announced that hot patching support is now generally available for Windows Server 2022 Azure Edition. The new hotpatch capability in Azure Automanage allows IT Admins to quickly deploy security updates on Windows Server virtual machines without frequent reboots.

The hotpatching support brings a bunch of benefits for Windows Server 2022 Azure Edition customers, including better security and streamlined update deployment. It should also help to significantly reduce the downtime for apps and services.

“Hotpatch works by first establishing a baseline with a Windows Update Latest Cumulative Update. Hotpatches are periodically released (for example, on the second Tuesday of the month) that build on that baseline. Hotpatches will contain updates that don’t require a reboot. Periodically (starting at every three months), the baseline is refreshed with a new Latest Cumulative Update,” explained Thomas Maurer, a Senior Cloud Advocate at Microsoft.
