Microsoft's 'Patch Tuesday' updates play a pivotal role in bolstering system security and performance. However, for enterprises managing a vast array of devices, these updates can pose a threat to business continuity. To mitigate this challenge, Microsoft is championing the 'Hotpatch' update approach. Hotpatch updates, often referred to as 'B' releases, are an integral part of the Windows Update ecosystem and must be implemented through Autopatch. In stark contrast to the comprehensive cumulative updates rolled out on the monthly 'Patch Tuesday', hotpatch updates are remarkably compact, encompassing solely security patches and excluding any feature enhancements. Moreover, they eliminate the need for a device reboot post-installation. Microsoft schedules 'baseline updates' that necessitate restarts in January, April, July, and October of each year. Meanwhile, hotpatch updates are disseminated in the intervening months. At present, the technical preview of hotpatching is exclusively accessible for Windows 365 and Windows 11 Enterprise Edition 24H2 systems, with devices mandatorily requiring Build 26100.2033 or a later version.
