There is no supported way in Windows to remap the physical Copilot key so that it behaves as an additional Ctrl key.
On Windows 11, the Copilot key is handled as a dedicated system key. By default it opens Microsoft Copilot or Microsoft 365 Copilot, and if Copilot is unavailable or disabled it opens Settings so the behavior can be customized for Copilot-related actions only. The documented customization is limited to choosing what Copilot-related experience the key launches, not to turning it into a standard modifier key such as Ctrl.
On Surface keyboards and similar devices, the Copilot-related keys can be configured only within the documented behaviors (open Copilot, open Windows Search, or open a contextual menu depending on Fn state). There is no documented option to change those keys into Ctrl.
Because of this, there is no “modern, universal” Windows feature that converts the Copilot key into a Ctrl key without relying on third‑party tools. Any such remapping would have to be done with external software or firmware-level options provided by the laptop manufacturer, which are not covered in the available documentation.
