An invisible button has been spotted in the File Explorer app on the latest Windows 11 preview builds. Currently, the button is non-functional, only appearing when you hover over a blank space in the navigation bar, but that hasn't stopped Windows Insider sleuths from looking into what it might be for.
Discovered by @phantomofearth, it appears the button will be tied to Copilot. Strings spotted in the current Windows 11 preview builds specifically mentions a feature called "Chat with Copilot," along with an option to detach the Copilot interface from the File Explorer window.
