Microsoft now testing hotpatch on Windows 11 24H2 and Windows 365

Microsoft announced Windows Hotpatch in preview for Windows 11 Enterprise 24H2 and Windows 365, allowing security updates to install in memory without reboots, except for quarterly cumulative updates that require a restart—reducing restarts from 12 to 4 annually. Eligible organizations (Windows Enterprise E3/E5 or Windows 365 Enterprise, Windows 11 24H2 build 26100.2033+, and Intune) can manage enrollment via Intune/Autopatch. At Ignite, Microsoft also introduced the $4M Zero Day Quest event and previewed new security capabilities including Administrator Protection, Quick Machine Recovery, Zero Trust DNS, and Config Refresh.
