Windows 11 Preview Build 25120 Starts Bringing “Conceptual Features” to Dev Channel

By Rafia Shaikh  / 

The Windows development team has released a new preview build for Windows Insiders in the Dev Channel. Unlike the last build, today's Windows 11 Insider Preview Build 25120 is also available for ARM64 devices.

Windows 11 Insider Build 25120 brings an experimental feature: a search box displayed on the desktop that enables you to search the web. With the Dev Channel, the company is now starting to test conceptual features that may not always make it to stable releases.

Windows 11 Insider Build 25120: Changes and Improvements


As described in our in our blog post here, 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. Today, Windows exposes this type of content in the Widgets board. To begin assessing this general idea and interaction model, the first exploration in this area adds a search box displayed on the desktop that enables you to search the web.

Example of interactive content on the desktop.

If you would like to remove this search box, you can right-click on the desktop, choose “Show more options,” and toggle the “Show search” option.

We are excited to learn your feedback on this interaction model, so please use the Feedback Hub to provide feedback if you receive this experiment.

NOTE: A reboot is required after updating to this build to trigger this experience but please note that not all Windows Insiders will have this experience enabled even after reboot.
