Many Windows devices will ship with a new hardware key. The Copilot key is a new key on the keyboard that activates the core AI feature of the operating system when pressed.
If that is all it does, it is probably the most useless key on the keyboard. Yes, it is worse than Scroll Lock.
The main reason is that Copilot sits on the taskbar already. A click opens the interface. Why would you need a key for that?
I’d take it back if Microsoft would add Copilot shortcuts to it, similar to how the Windows-key works. Press Copilot Key and V, and Copilot gives you an analysis of the Clipboard content. Something like that.
How to remap the Copilot key

Good news is that you can remap the Copilot Hardware Key. Right now, you may do so either through a policy or directly in the Registry. Tero Alhonen published the information on X.
Since Windows Home admins have no access to the Policy Editor, it is easier to remap the key in the Registry.
Here is how it is done:
- Open the Start menu.
- Type regedit and select Registry Editor from the list of results.
- Confirm the UAC prompt by selecting the option Yes.
- Navigate to HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Windows\CopilotKey
- Note: if a key does not exist, right-click on the previous key and select New > Key. Name it accordingly and proceed.
- Right-click on CopilotKey and select New > Dword (32-bit) Value.
- Name it SetCopilotHardwareKey.
- Double-click on SetCopilotHardwareKey and set its value to 1.
- Right-click on CopilotKey again and select New > String Value.
- Name it EnterAppAumid.
- Double-click on it and paste the Application User Model ID of an installed app into the field.
- Close the Registry Editor.
- Restart Windows.
Background information: The AUMID / AppID (Application User Mode ID) is used by Windows to “identify and differentiate applications for switching, launching, telemetry, and functions”.
You can get the IDs of all installed apps in the following way:
- Open the Start menu.
- Type Terminal and select the Terminal app.
- Type Get-StartApps and press the Enter-key in the Terminal window.
The list of IDs of installed apps is returned. You need to copy the entire ID, e.g. Microsoft.WindowsCalculator_8wekyb3d8bbwe!App, as the value of EnterAppAumid in the Registry.
