Microsoft Extends Hotpatching Support for Windows Server 2022 to 2027

Microsoft has announced an extension of hotpatching support for Windows Server 2022 Datacenter: Azure Edition until October 2027, one year beyond the mainstream end date of October 13, 2026. This feature allows administrators to apply security updates without requiring a full server reboot, thus minimizing downtime. However, it is important to note that this extension applies only to the Azure Edition and not to on-premises installations. Hotpatching has been available since February 2022 and is designed to patch in-memory code of running processes, allowing for uninterrupted service. While monthly security updates can be applied without a restart, quarterly cumulative updates still require one. Microsoft aims to enhance the update experience for organizations utilizing Azure services. The extension of hotpatching is part of Microsoft's broader strategy to promote its cloud services.

Key Points: • Hotpatching for Windows Server 2022 Azure Edition extended to October 2027. • Feature allows security updates without server reboots, reducing downtime. • Extension applies only to Azure Edition, not on-premises installations.
