Answer 1

Hi Amy Sheffield, 

Thanks for sharing the details. I understand how frustrating this can be, especially since Copilot is not responding in both new prompts and existing conversations, even after you already tried repairing the app, signing out and back in, and resetting the PC. 

To narrow this down, could you please confirm a few things? 

• Are you using the Copilot app on Windows, Copilot in Microsoft Edge, or Copilot through the Microsoft 365 app/web? 
• When you send a prompt, does Copilot show any error message, keep loading, or simply stay blank with no response? 
• Does the same issue happen if you try Copilot from a browser, such as Copilot on the web, instead of the Windows app? 
• What Windows version/build and Copilot app version are currently installed? 

In the meantime, please try these checks: 

• Open the Get Help app and search for Copilot connectivity troubleshooter, then run it.  
• Try accessing Copilot from the web version. 
• Make sure Windows, Microsoft Edge, Microsoft Edge WebView2 Runtime, and Microsoft Store apps are fully updated, then restart the device. 
• Reset the Microsoft Store cache by pressing Win + R, typing wsreset.exe, and pressing Enter. After the Store opens again, check for app updates. 
• If you are using VPN, proxy, third-party antivirus, or a managed network, temporarily test without them if possible. 

Wishing you a smoother experience with Copilot on Windows going forward. While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding.

Copilot on Windows can become unresponsive if there are active Copilot conversations or if the app installation is in a bad state.

Try the following steps in order:

1. Close active Copilot conversations
   • If using experimental Copilot Actions or agentic features, close any Copilot conversation windows.
   • In the system tray, select the Copilot icon, right-click it, and select Quit to fully close Copilot.
   • Reopen Copilot and test a new prompt.
2. Fully uninstall and reinstall the Copilot app
   • On Windows 11: Go to Settings > Apps > Installed apps, search for Copilot, select … and then Uninstall.
   • On Windows 10: Go to Settings > Apps, search for Copilot, and select Uninstall.
   • After uninstall completes, reinstall Copilot from the Microsoft Store and try again.
3. Check for known issues with experimental agent features
   • If enrolled in builds with experimental agentic features (agent workspace / Copilot Actions), be aware that active conversations can prevent normal behavior and even block sleep or shutdown. Ensure all Copilot Actions conversations are closed and Copilot is quit from the tray before testing again.

If Copilot remains completely unresponsive after these steps, collect details (Windows version, Copilot app version, and whether experimental features are enabled) and contact Microsoft support for further investigation.
