Co-pilot Issue

Repair the Microsoft Copilot app first; if the white screen remains, reset it and then reinstall it from Microsoft Store.

1. Repair and reset Copilot

1. Close Copilot.
2. Open Start → Settings → Apps → Installed apps.
3. Find Microsoft Copilot, select the three-dot menu → Advanced options.
4. Select Repair.
   • Repair attempts to reload the app while retaining its data.
5. Reopen Copilot and check whether the chat interface appears.
6. If it remains white, return to the same page and select Reset → Reset. Windows documents Repair followed by Reset as the standard sequence for an app that is not working correctly.^1^

Note: Reset permanently removes the app’s local data, preferences, and saved sign-in state, so sign-in may be required again.^2^

2. Reinstall Copilot if Reset does not work

1. Open Settings → Apps → Installed apps → Microsoft Copilot.
2. Select the three-dot menu → Uninstall.
3. Restart Windows.
4. Open Microsoft Store, search for Microsoft Copilot, and install it again.
5. Launch Copilot and sign in.

Resetting and then reinstalling Copilot is also the accepted resolution path for a Microsoft Copilot app that stops loading after an update.^3^

3. If a clean installation still shows white

Run the dedicated connectivity diagnostic:

1. Open Start, search for Get Help, and launch it.
2. Enter Copilot connectivity troubleshooter in the search box.
3. Start the troubleshooter and apply its recommendations.
4. Review its results for a firewall rule or another network blocker.

Microsoft provides this troubleshooter specifically for difficulty connecting to Copilot; it checks firewall rules and other connection blockers.^4^

If possible, also test Copilot briefly on another network, such as a mobile hotspot. If it works there, the laptop installation is functional and the original network, VPN, proxy, security software, or organizational firewall needs investigation. For an organization-managed laptop, provide the Get Help results to the IT administrator.

If none of these steps resolves it, press Windows key + F to open Feedback Hub and report the issue under Copilot, including a screenshot and diagnostic data.^3^
