In this article, we will talk about the latest Windows 11 Build from the Dev Channel, and also about Windows 11 25H2.
The Dev Channel is jumping ahead to receive 26200 series builds. This means that the window to switch from the Dev Channel to the Beta Channel is closed and once Build 26200.5510 is installed. If you are in the Dev Channel today and still want to switch to the Beta Channel at the last minute, when Build 26200.5510 is offered you can pause updates in Windows Update and switch your channel to the Beta Channel and un-pause updates.
These 26200 series builds are based on Windows 11, version 24H2 and will contain many of the same features and improvements as the 26120 series builds that will continue to be released in the Beta Channel. Over time, Microsoft will be making behind-the-scenes platform changes in these builds and these builds may have different known issues because of those changes than what we’re flighting to the Beta Channel.

In the case of Build 26200.5510 today – this build contains the same features and improvements as Build 26120.3576 released previously.
The Dev Channel not moving to 25H2, likely means that 25H2 will only be an Enablement Package, with no platform change from Germaniun.
This is most likely caused by the fact that Microsoft hasn’t got any important new features for 25H2 and also they are trying to make the switch to Windows 11 easier for Windows 10 users, as the support for Windows 10 is ending.
