Microsoft Extends Windows Server 2022 Hotpatching Through October 2027

[harlan4096]

Microsoft has extended support for Windows Server 2022 hotpatching by one year, with the new end date set for October 2027. This change is effective immediately.

The extension applies only to systems running Windows Server 2022 Datacenter: Azure Edition that are enrolled in hotpatch updates. The hotpatch update schedule remains the same through the new end date.

This extension does not affect the mainstream support for Windows Server 2022, which still ends in October 2026 for general updates.

The extended support end dates for Windows Server 2022 editions are as follows: Datacenter, Datacenter: Azure Edition, Essentials, and Standard versions will reach their end of support on October 14, 2031.

However, servers still need to be restarted after installing updates through the regular Windows Update channel. Updates like Windows non-security patches and non-Windows updates such as .NET patches cannot be installed without a restart.
