Analysis
Introduction to Windows 11 26H2
The next annual update for Windows 11 is coming soon, and Microsoft has already made it available to Windows Insiders in the Dev Channel. This update, known as Windows 11 version 26H2, continues Microsoft's focus on delivering a predictable and low-disruption update experience for organizations and IT professionals.
Upgrade Process
Devices running Windows 11 24H2 and 25H2 will be able to upgrade to version 26H2 through a small enablement package, which will activate dormant features already on the device. This package is only 174 KB in size, and the update will require only a quick restart. Once installed, the update will enable the new feature set and change the operating system's build number to 26300.
Shared Servicing Model
Microsoft has also published a new whitepaper detailing its shared servicing model, which confirms that Windows 11 versions 24H2, 25H2, and 26H2 all share the same servicing branch. This means that security updates, testing baseline, and underlying source code are the same for these releases, allowing Microsoft to deliver the upgrade through a small enablement package. Systems running Windows 11 23H2 and older releases do not share the same servicing branch and will require the full update, which is 6.5 GB in size.
