Microsoft just gave Windows Server 2022 users an extra year before they need to reboot for hotpatches. Support now runs through October 2027 — a full year past the mainstream end date.
Here’s the catch: only Server 2022 Datacenter: Azure Edition enrolled in hotpatch updates qualifies. If you’re running Standard, Essentials, or regular Datacenter, this extension doesn’t apply. Those editions still have mainstream support ending October 2026 and extended support through October 2031.
For those who do qualify, hotpatching means security updates install directly into running processes. No restarts. No downtime windows. Non-security updates and patches from outside Windows (like .NET) still require a reboot.
Microsoft says the extension helps organizations “maintain uptime, reduce servicing disruptions, and shorten the time it takes to respond to vulnerabilities.” Hyperbole aside, anything that reduces forced reboots in production environments is worth paying attention to.
Hotpatching has been available for Windows Server Azure Edition since 2022. Microsoft’s also rolling it out to Windows 11 Enterprise and plans to enable it by default for Intune-managed devices starting with the May 2026 security update.
