Issue withCopilot

Repair the Copilot app first; if its window alone remains blank, reset it, reinstall it from Microsoft Store, and then run the Copilot connectivity troubleshooter.

1. Repair or reset Copilot

1. Open Start → Settings → Apps → Installed apps.
2. Find Copilot, select … → Advanced options.
3. Select Repair, then reopen Copilot.
4. If the screen remains blank, return to the same page and select Reset. Resetting removes the app’s locally stored data and settings. Microsoft documents this repair-then-reset sequence for Windows apps that are not running correctly.^1^

2. Update Windows and Copilot

1. Go to Settings → Windows Update → Check for updates, install available updates, and restart the PC.
2. Open Microsoft Store → Library → Get updates.
3. Allow updates for Copilot and Microsoft Store to finish, then test Copilot again.^2^

3. Reinstall Copilot if it is still blank

1. Open Settings → Apps → Installed apps.
2. Find Copilot, select … → Uninstall.
3. Restart Windows.
4. Open Microsoft Store, search for Microsoft Copilot, and install it again.

Copilot on Windows officially supports removal through Windows Settings and reinstallation from Microsoft Store.^3^

4. Check whether connectivity is blocking both loading and uploads

1. Open the Windows Get Help app.
2. Search for Copilot connectivity troubleshooter.
3. Run it and apply any suggested remedy.

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

Also test Copilot in a browser at copilot.com, using the same account:

• Browser works, Windows app is blank: the issue is isolated to the installed app; complete the reset/reinstall steps above.
• Browser and app both fail: test another network and temporarily disconnect any VPN. If that works, review the original network’s firewall or filtering configuration.
• Copilot loads but only uploads fail: sign out and sign back in with the account intended for Copilot, then retry the upload.

If the subscription was upgraded or renewed within the last 24 hours, file-upload permissions can take up to 24 hours to synchronize. After that period, sign out and back in with the licensed account; if uploading still fails, contact Microsoft Support.^5^

If the entire Windows display is blank

The preceding steps apply when only the Copilot window is blank. If the desktop and other applications are also blank, press Windows + Ctrl + Shift + B to reset the graphics driver. Microsoft’s Windows blank-screen guidance also recommends Ctrl + Alt + Delete and Windows + P to test the security screen and display mode.^6^

If the problem remains, open Copilot’s … → Send feedback → Report a problem and include when it started, the Windows version, whether the browser test worked, and a screenshot.^7^
