Disable Windows Copilot Completely with Regedit

This guide explains how to permanently disable Windows Copilot across your entire Windows 11 system by modifying the Windows Registry (Regedit). By adding a specific policy key to the registry, you can turn off the AI assistant, eliminate the Copilot sidebar, and remove the icon from the taskbar for all user accounts on the machine.

Step 1: Open the Registry Editor

  1. Press Windows Key + R to open the Run dialog box.
  2. Type regedit and press Enter (or click OK).
  3. Click Yes when prompted by User Account Control (UAC).

Step 2: Navigate to the Windows Policies Key

In the address bar at the top of the Registry Editor window, paste the following path and press Enter:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows

(Note: Applying this under HKEY_LOCAL_MACHINE disables Copilot for all users on the machine. If you only want to disable it for the current logged-in user, navigate to HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows instead.)

Step 3: Create the WindowsCopilot Key

  1. Right-click on the Windows folder (key) in the left sidebar.
  2. Select New > Key.
  3. Name the new key WindowsCopilot and press Enter.

Step 4: Create and Configure the DWORD Value

  1. Click on the newly created WindowsCopilot folder to select it.
  2. Right-click anywhere in the empty space on the right pane.
  3. Select New > DWORD (32-bit) Value.
  4. Name this value TurnOffWindowsCopilot and press Enter.
  5. Double-click TurnOffWindowsCopilot.
  6. Set the Value data field to 1.
  7. Ensure the Base is set to Hexadecimal, then click OK.

Step 5: Apply the Changes

To finalize the modification and completely remove Copilot: 1. Close the Registry Editor. 2. Restart your computer, or restart Windows Explorer via Task Manager (Ctrl + Shift + Esc > right-click Windows Explorer > select Restart).

Windows Copilot is now completely disabled on the system. If you ever want to re-enable it, return to the WindowsCopilot key in the Registry Editor and change the TurnOffWindowsCopilot value data to 0, or delete the WindowsCopilot key entirely.
