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
- Close Copilot.
- Open Start → Settings → Apps → Installed apps.
- Find Microsoft Copilot, select the three-dot menu → Advanced options.
- Select Repair.
- Repair attempts to reload the app while retaining its data.
- Reopen Copilot and check whether the chat interface appears.
- 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
- Open Settings → Apps → Installed apps → Microsoft Copilot.
- Select the three-dot menu → Uninstall.
- Restart Windows.
- Open Microsoft Store, search for Microsoft Copilot, and install it again.
- 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:
- Open Start, search for Get Help, and launch it.
- Enter Copilot connectivity troubleshooter in the search box.
- Start the troubleshooter and apply its recommendations.
- 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^
