Microsoft Extends Hotpatch Support for Windows Server 2022 Datacenter Until 2027 Microsoft has announced an extension of hotpatch update support for Windows Server 2022 Datacenter: Azure Edition until October 2027. This extension allows organizations to apply security updates without requiring a system reboot, which is crucial for maintaining uptime in mission-critical workloads. The hotpatching feature is exclusive to the Azure Edition and enables in-memory code updates, significantly reducing downtime. However, updates that require a traditional reboot, such as non-security updates, will still necessitate a restart. The extension is effective immediately and maintains the existing hotpatch cadence. This move aligns with Microsoft's ongoing shift towards cloud services and emphasizes the importance of uptime in today's digital landscape. Organizations must ensure they are enrolled in hotpatch updates to benefit from this extension. 5 sources 28
