Microsoft has unveiled an innovative approach to enhancing the delivery of continuous innovation with the introduction of Windows 11 checkpoint cumulative updates. These updates are set to transform the update experience for devices running Windows 11 and Windows Server 2025, focusing on smaller, faster, and more sustainable updates.
Overview of Checkpoint Cumulative Updates
Windows 11 quality updates utilize servicing technology, building cumulatively from the time a new Windows OS was released to manufacturing (RTM). These updates encompass all changes since RTM in the form of binary differentials computed from the initial version of those binaries. With the introduction of Windows 11, version 24H2, Microsoft is rolling out a new concept of checkpoint cumulative updates. These updates enable users to receive features and security enhancements through smaller, incremental differentials containing only the changes since the previous checkpoint cumulative update. This leads to significant savings in time, bandwidth, and hard drive space. Going forward, Microsoft plans to periodically release cumulative updates as checkpoints, with subsequent updates consisting of:- Update package files associated with the checkpoints
- New update package files containing incremental binary differentials against the binary version in the last checkpoint This iterative process of generating multiple checkpoints during the lifecycle of a Windows release allows the Windows 11, version 24H2 servicing stack to merge all checkpoints and download/install missing content only on the device.
Managing Checkpoint Cumulative Updates
For users managing updates through Windows Update, Windows Update for Business, Windows Autopatch, or Windows Server Update Services (WSUS), these new developments do not necessitate any changes or actions. They will manifest as regular monthly updates while offering improved functionality. For devices running Windows 11, version 24H2 or later, and Windows Server 2025, the checkpoint cumulative updates bring a seamless experience without requiring additional user intervention. Users can preview this optimized update experience with Windows Insider Preview Build 26120.1252 in the Dev Channel.Benefits and Improvements
Windows users can now benefit from enhanced ways to stay current with the latest feature and security enhancements. The advantages of checkpoint cumulative updates include: - Smaller Downloads to Clients: By generating binary differentials against the latest checkpoint instead of the RTM version, subsequent cumulative updates are smaller and faster to apply.
- Server-side Sustainable Redistribution: Updates are no longer packaged in a single file but are efficiently redistributed to frontline servers or remote branch offices, utilizing file-level deduplication for incremental downloads.
- Optimized Feature Update Delivery: Delivering annual feature updates using enablement packages ensures a common core OS with the previous release, simplifying update scaling and adoption. These optimizations align with the continuous innovation model of Windows 11, helping organizations improve security posture and compliance by ensuring devices are always updated to the latest Windows 11 version. Microsoft encourages users to explore the preview experience today with Windows Insider Preview Build 26120.1242 in the Dev Channel, emphasizing continuous delivery of innovation and improvements for better device protection and productivity. In conclusion, the introduction of Windows 11 checkpoint cumulative updates marks a significant step towards enhancing the update experience for Windows users, providing a more streamlined, efficient, and sustainable approach to delivering feature and security enhancements.
