In this article, we will talk about the latest Preview Build for Windows 11 26H2 in the Dev Channel, which is the Build 26300.8553.
These 26300 series builds will contain many of the same features and improvements as the 26220 series builds that will continue to be released in the Beta Channel. Over time, Microsoft will be making behind-the-scenes platform changes in each build so they may have different known issues because of those changes. These Builds are previewing Features that will be part of Windows 11 26H2, the Big Annual Release for 2026.
