How to Disable Windows 11 Copilot to Reclaim System Resources

What Causes This?

Windows 11 Copilot runs as part of the Windows shell and can stay available in the background even if you rarely use it. On some PCs, especially those with limited RAM or many startup apps, this adds extra memory use and background activity that can make the system feel less responsive. Microsoft has also changed how Copilot is integrated across different Windows 11 versions, so the way it appears and how much it affects performance can vary.

Common Symptoms

• Higher RAM or CPU usage than expected when the desktop is idle
• Slower startup or lag when opening apps
• Copilot icon appearing on the taskbar even when you do not use it
• Extra background processes running in Task Manager
• Noticeable slowdown on lower-end laptops or older PCs

How to Fix It Manually

1. Turn off Copilot from the taskbar settings

   1. Right-click an empty area of the taskbar.
   2. Click Taskbar settings.
   3. Under Taskbar items, find Copilot.
   4. Switch it Off.
   5. Restart your PC and check whether performance improves.

2. Disable Copilot through Group Policy
   This option is available on Windows 11 Pro, Enterprise, and Education.

   1. Press Windows + R, type gpedit.msc, then press Enter.
   2. Go to:
      User Configuration > Administrative Templates > Windows Components > Windows Copilot
   3. Double-click Turn off Windows Copilot.
   4. Select Enabled, then click Apply and OK.
   5. Restart Windows Explorer or reboot the PC.

3. Disable Copilot through the Registry
   Use this method if you are on Windows 11 Home. Be careful when editing the registry.

   1. Press Windows + R, type regedit, then press Enter.
   2. Go to:
      HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows
   3. If you do not see a WindowsCopilot key:
      • Right-click Windows
      • Select New > Key
      • Name it WindowsCopilot
   4. Inside WindowsCopilot, right-click the right pane and choose New > DWORD (32-bit) Value.
   5. Name it TurnOffWindowsCopilot.
   6. Double-click it and set Value data to 1.
   7. Click OK, close Registry Editor, and restart your PC.

4. Check Task Manager for leftover background load

   1. Open Task Manager with Ctrl + Shift + Esc.
   2. Click Processes and look for unusually high CPU or Memory use.
   3. Click the Startup apps tab.
   4. Disable apps you do not need launching at startup by right-clicking them and choosing Disable.
   5. This helps reduce the overall background load so disabling Copilot has a bigger effect.

5. Restart Windows Explorer if Copilot still appears

   1. Open Task Manager with Ctrl + Shift + Esc.
   2. In the Processes tab, find Windows Explorer.
   3. Right-click it and select Restart.
   4. If the Copilot icon is still present after that, reboot the PC.
