Release notes for Hotpatch on Windows 11 Enterprise version 25H2

Hotpatch for Windows 11 Enterprise, version 25H2 gives organizations the ability to apply security updates without requiring a device restart. This helps maintain security while keeping workflows uninterrupted.

Hotpatch is an extension of Windows Update and requires Autopatch to create and deploy updates to devices enrolled in the Autopatch quality update policy.

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 monthly standard security updates released on the second Tuesday of every month.

• Minimized disruptions. Users can continue their work without interruptions while Hotpatch updates are installed. Hotpatch updates don't require the PC to restart for the remainder of the quarter.

  Note: OS features, firmware, or application updates might still require a restart during the quarter.
