Pressing the Windows key typically opens the Start menu, but Microsoft is considering expanding its functionality as part of a new Search experience. The upcoming Windows Search UI will operate independently from the Start menu, which will still trigger the old Search. This new interface allows users to eliminate Bing results and introduces a feature called "Actions" for quick adjustments to settings. Microsoft plans to eventually unify the two search experiences, but the distinct design of the new Search may require adjustments to the Start menu.
Currently, Microsoft has not confirmed if pressing the Windows key will redirect users to Search instead of the Start menu. There is potential for the Windows key to evolve to include more Actions, such as sending emails directly. Observations indicate that the legacy Search UI still appears when using the Start menu, but this is expected to change next year.
Windows Search has faced challenges, including sluggish performance, prioritization of Bing results over local outcomes, and issues with typo detection. In March 2026, Microsoft committed to enhancing Windows Search, including testing a toggle to disable Bing and Store results. The new Search will allow users to interact with Windows Settings through commands and may include the ability to send emails directly from Windows Search.
