Disable Windows Copilot for All Users via Regedit

This guide explains how to completely disable the Microsoft Copilot integration across all local operating system accounts on Windows 11 using the Registry Editor (Regedit). By adding a specific policy entry to the HKEY_LOCAL_MACHINE registry hive, you can remove the Copilot interface, prevent it from launching, and ensure the setting applies globally to every current and future user on the machine.

Step 1: Open the Registry Editor with Administrative Privileges

  1. Press Windows Key + R to open the Run dialog box.
  2. Type regedit into the field.
  3. Press Ctrl + Shift + Enter (or click OK and accept the User Account Control prompt) to launch the Registry Editor as an administrator.

Step 2: Navigate to the Windows Policy Key

Use the left sidebar or copy and paste the following path into the address bar at the top of the Registry Editor:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows

Step 3: Create the WindowsCopilot Key

  1. Right-click the Windows folder in the left navigation pane.
  2. Select New > Key.
  3. Name the new key: WindowsCopilot (If a key named WindowsCopilot already exists, skip this step).

Step 4: Create and Configure the Value

  1. Select the WindowsCopilot key in the left pane.
  2. Right-click inside the empty area in the right pane.
  3. Select New > DWORD (32-bit) Value.
  4. Name the new value: TurnOffWindowsCopilot
  5. Double-click TurnOffWindowsCopilot to edit its properties.
  6. Under Value data, change the value from 0 to 1.
  7. Ensure the Base is set to Hexadecimal, then click OK.

Step 5: Apply the Changes

To apply the changes system-wide across all user accounts: * Restart your computer, or * Restart Windows Explorer via Task Manager (Ctrl + Shift + Esc > right-click Windows Explorer > select Restart).

After the restart, the Copilot icon will be removed from the taskbar, the shortcut (Windows Key + C) will be deactivated, and the feature will be disabled for all local user accounts.

To re-enable Windows Copilot in the future, return to the WindowsCopilot registry key and either change the TurnOffWindowsCopilot value data back to 0 or delete the TurnOffWindowsCopilot value entirely.
