Windows Search May Soon Use Your Default Browser and Engine

29 Sep 2025

Recent discoveries in the Edge Canary version reveal that Microsoft is evaluating a notable change in the functionality of the Windows Search feature. Previously, search queries submitted through the taskbar were funneled exclusively into Microsoft's Edge browser and the Bing search engine. However, newly identified flags like msExplicitLaunchNonBingDSE and msExplicitLaunchNonBingDSEAndNonEdgeDB suggest a shift towards honoring the user's choice of search engine and browser settings.

Experimental Features Indicate a Shift

The flags, including variations such as msWSBLaunchNonBingDSE and msWSBLaunchNonEdgeDB, are believed to tie directly to a more open framework for Windows Search Box's functionality. Notably, WSB stands for Windows Search Box and DSE represents Default Search Engine. Once implemented, this update may allow Windows users to conduct searches directly in their chosen browsers rather than being redirected to Edge, deviating from the current behavior that mandates Bing as the default search platform.

This test phase is currently confined within Microsoft's Edge Canary, a version widely recognized for hosting experimental and developmental functions. As with any trial feature, there's a potential these changes might not advance into a stable release, yet it signifies Microsoft's awareness and potential shift in addressing user feedback for more flexible and user-oriented features.

Implications for Users and Developers

If these changes are integrated into future versions of Windows, it would mark a significant pivot in how Windows approaches search functionalities, particularly respecting personal preferences in default internet tools. This move could have positive ripple effects for developers of other web browsers, offering an even playing field and encouraging consumer choice. The exploration of these functions underscores Microsoft's ongoing effort to enhance user satisfaction and address concerns about the entrenched use of its own products throughout the operating system.

This potential development could reshape how default applications are perceived within an ecosystem tightly controlled by its own suite of software. As Microsoft tests these waters, it remains to be seen how this will influence broader strategies relating to application integration and competition with other major tech players. For now, Windows users can look forward to the possibility of more freedom in their search options, symbolizing some degree of openness previously unseen on this platform.
