microsoft autopatch

Microsoft Autopatch is a cloud-based service that automates Windows and Microsoft 365 update management for enterprise devices. Discussions on WindowsForum.com cover how Autopatch handles Windows 11 hotpatch deployments, which apply monthly security fixes without requiring a restart. However, Microsoft's Message Center advisory MC1462918 notes that the September 2026 security release will be a standard update for hotpatch-enabled devices because it changes security-related components that cannot be updated in memory. This means a restart will be necessary in September 2026, even though that month was originally part of the no-reboot cycle. The service relies on baseline servicing for updates that hotpatch cannot handle, ensuring devices remain secure and compliant.
