Hotpatch updates for Windows 11 Enterprise give you the ability to apply security updates without restarting a device. This helps keep client computers up to date, productive, and more secure. You can manage and apply updates using Windows Autopatch for devices running Windows 11 Enterprise, version 26H2.
Benefits include:
- Immediate protection: Hotpatch updates take effect immediately upon installation, providing rapid protection against vulnerabilities.
- Consistent security: Devices receive the same level of security patching as the standard monthly security updates released on the second Tuesday of every month.
- Minimized disruptions: Users can continue their work without interruptions while hotpatch updates are installed. After a quarterly baseline update, hotpatch updates don't require the PC to restart for the remainder of the quarter. OS features, firmware, or application updates might still require a restart during the quarter.
