Fix Windows 11 Copilot Using Too Many Resources

Windows 11 Copilot can sometimes use more CPU, memory, or background activity than expected, especially if it stays loaded in the sidebar, starts with Windows, or keeps calling web-based services in the background. High resource usage is also more noticeable on PCs that already have many startup apps, browser processes, or limited RAM. In some cases, the issue is not Copilot alone, but the extra background load around it.

What Causes This?

Copilot relies on background Windows components, web content, and Microsoft services, so it can use more resources when it stays active for long periods or reloads often. Resource spikes are more common after Windows updates, when startup apps are competing for RAM, or when Edge/WebView-related processes are already consuming memory. On lower-spec PCs, even moderate Copilot activity can feel excessive.

Common Symptoms

• CPU usage jumps when Copilot opens or stays pinned
• Memory usage stays high even when you are not actively using it
• Fans run louder or the laptop gets warmer than usual
• Windows feels slow when switching apps or opening the Start menu
• Task Manager shows Copilot, Edge, or WebView processes using significant resources

How to Fix It Manually

1. Check whether Copilot is actually causing the spike

   1. Open Task Manager with Ctrl + Shift + Esc.
   2. Click Processes.
   3. Sort by CPU or Memory.
   4. Look for Copilot, Microsoft Edge, or WebView2 processes rising when Copilot is open.

2. Close Copilot and see if usage drops

   1. If Copilot is open, close its panel or window.
   2. In Task Manager, right-click the related process and choose End task if it stays running.
   3. Wait 30-60 seconds and check whether CPU or memory returns to normal.

3. Disable Copilot from the taskbar

   1. Right-click the taskbar and select Taskbar settings.
   2. Find Copilot under taskbar items.
   3. Turn the toggle Off.
   4. Restart your PC and check if performance improves.

4. Reduce background apps and startup load

   1. Open Settings > Apps > Startup.
   2. Turn off apps you do not need launching at startup, especially browsers, chat apps, game launchers, and utilities.
   3. Then go to Settings > Apps > Installed apps and remove software you no longer use.
   4. Fewer background apps means Copilot has less competition for RAM and CPU.

5. Update Windows and Edge/WebView components

   1. Open Settings > Windows Update.
   2. Click Check for updates and install anything pending.
   3. Open Microsoft Edge, click the three dots > Help and feedback > About Microsoft Edge, and let it update.
   4. Restart your PC after updates finish.

6. Turn off background permissions for unnecessary apps

   1. Open Settings > Apps > Installed apps.
   2. Select an app you rarely use, click the three dots > Advanced options if available.
   3. Under background permissions, choose a more restrictive option or disable background activity where possible.
   4. This helps reduce the total background load that makes Copilot slow your system down.

7. Use Task Manager to identify other hidden resource hogs

   1. In Task Manager, click Startup apps and disable high-impact items you do not need.
   2. Return to Processes and watch for antivirus scans, sync tools, browser tabs, or update services using resources at the same time as Copilot.
   3. If Copilot only spikes when other apps are busy, the real issue may be overall system load, not Copilot alone.
