Microsoft announced a public preview of Hotpatching for Windows Server 2025, enabling in-memory installation of security updates without reboot to reduce downtime and exposure, with quarterly scheduled reboots instead of monthly. The feature—available via Azure Arc—requires Windows Server 2025 Datacenter evaluation, Virtualization Based Security, the July KB5040435 security update, and Azure Arc connectivity; non-security and certain updates (e.g., .NET) still need reboots, and support extends across on-prem and various hypervisors.
