What’s New in Windows 11 Insider Preview Build 25120

Here is the complete changelog of the new build:

Changes and Improvements


As described 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.

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 the reboot.
