Run the Copilot connectivity troubleshooter first, then repair, reset, and reinstall the Windows Copilot app only if the blank page remains.
1. Check Copilot connectivity
- Open Start, search for Get Help, and open it.
- Enter Copilot connectivity troubleshooter in the search box.
- Run the troubleshooter and apply any recommended fixes.
- Reopen Copilot.
This checks for firewall rules and other connection blockers that can leave Copilot unable to load its page. ^1^
2. Repair the Copilot app
If connectivity passes but Copilot remains blank:
- Open Start → Settings → Apps → Installed apps.
- Find Copilot.
- Select the … menu → Advanced options.
- Select Repair.
- When repair finishes, open Copilot and test it.
If Repair is unavailable or does not resolve it, return to the same page and select Reset. ^2^
Reset is more extensive than Repair, so try Repair first.
3. Reinstall Copilot
If reset also fails:
- Go to Settings → Apps → Installed apps.
- Find Copilot, select …, and choose Uninstall.
- Open Microsoft Store, search for Microsoft Copilot, and install it again.
- Launch it and sign in with the Microsoft account normally used for Copilot.
Microsoft documents Copilot as a removable Windows app that can be reinstalled from Microsoft Store. ^3^
If only Edge Copilot is blank
If the icon is inside the Microsoft Edge sidebar, rather than the standalone Windows app:
- Confirm ordinary websites load.
- Sign out of the Edge profile and sign back in.
- Close and reopen the sidebar.
- On a work or school device, ask the administrator to check whether Edge sidebar policies or firewall rules block Copilot.
Microsoft’s Edge-specific guidance identifies connectivity, authentication, and managed sidebar policies as causes of a blank Copilot pane. ^4^
Report it if the page remains blank
In Copilot, select … → Send feedback → Report a problem and include:
- When the problem began
- Windows version
- Whether the standalone app and Edge version are both affected
- A screenshot of the blank page
Microsoft requests those details when investigating persistent Copilot app problems. ^5^
