Just in case you were waiting on a brand new Insider Preview Build for the latest Microsoft-designed operating system, know that the drought is over.

The Redmond tech giant released Build 25120 to the Dev Channel today. This is the Sun Valley 3 development for Windows Insiders, which will eventually become the version that will be released in 2023.

Microsoft mentioned that, unlike the previous build, this one is now available for ARM64 PCs, and there are also ISOs that can be downloaded.

Changes and improvements

[General]

As described in a recent blog post, Windows Insiders who use the Dev Channel may get to try out new ideas, longer lead features, and experiences that are intended to help validate concepts.

Starting with this preview build, some Insiders will see one of these conceptual features as we begin to explore exposing lightweight interactive content on the Windows desktop.
