Microsoft introduced a dedicated Copilot key on its PCs in 2024 to enhance AI branding, but later shifted the strategy to pin Copilot as a web app on the Taskbar, making the key less essential. Users can customize the Copilot key in Windows 11 to either launch Windows Search or a selected application, but customization options are limited to signed MSIX packages, excluding third-party applications. For greater flexibility, users can utilize third-party tools like PowerToys to remap keys. Microsoft is also experimenting with a context menu activation for the Copilot key.
