How to fix CoPilot

Repair the Copilot app first, then reset or reinstall it only if the white window remains.

1. Repair Copilot

On Windows 11:

1. Open Start → Settings → Apps → Installed apps.
2. Find Copilot.
3. Select the … menu → Advanced options.
4. Select Repair.
5. Open Copilot, submit a short prompt, and check whether the response renders.

2. Reset Copilot if repair does not work

Return to Settings → Apps → Installed apps → Copilot → Advanced options, and select Reset.^1^

Reset can clear the app’s local data and sign-in state. Reopen Copilot afterward and sign in again with the account you normally use. Microsoft recommends checking that the same account or sign-in method is being used with the updated Copilot app.^2^

3. Reinstall Copilot if it is still blank

1. Windows 11: Open Settings → Apps → Installed apps.
   • For Windows 10, use Settings → Apps.
2. Find Copilot, select its menu, and choose Uninstall.
3. Open Microsoft Store, search for Microsoft Copilot, and install it again.
4. Launch it from Start and test it before pinning it back to the taskbar.

Microsoft documents uninstalling Copilot from Windows Settings and reinstalling it from Microsoft Store.^3^

4. If the app alone remains white, test connectivity

Open Copilot in a private browser window and sign in with the same account. If Copilot works in the browser but not in the Windows app, the problem is localized to the app or its Windows configuration.

Then run Microsoft’s connectivity check:

1. Open Start and search for Get Help.
2. In Get Help, enter Copilot connectivity troubleshooter.
3. Run the troubleshooter and apply any recommended remedy.

This checks for firewall rules and other connection blockers.^4^

Also update the Store-delivered app:

1. Open Microsoft Store.
2. Select Library → Get updates.
3. Install available Copilot or Microsoft Store updates.^5^

5. Report it if all tests fail

If both the reinstalled app and browser version fail, or the troubleshooter reports no blocker:

• In Copilot, select … → Send feedback → Report a problem.
• Include when it began, the Windows version, whether the browser test worked, and a screenshot of the white window.^2^

The laptop’s general slowness may be separate from Copilot’s blank window. Avoid graphics-driver or Windows blank-screen recovery procedures unless the entire Windows desktop—not only Copilot—also becomes blank.
