Copilot Not Opening

Reset Microsoft Copilot’s app data in Windows 11, since reinstalling has already failed to clear the blank-screen condition.

1. Repair, then reset Copilot

1. Open Start → Settings → Apps → Installed apps.
2. Find Microsoft Copilot.
3. Select the More (⋯) button → Advanced options.
4. Select Repair, then reopen Copilot.
5. If it remains blank, return to the same page and select Reset.

Reset removes the app’s local data and settings, so you may need to sign in again. Microsoft recommends this Repair/Reset sequence for Windows apps that are not running correctly.^1^

2. Run the Copilot connectivity troubleshooter

If resetting does not resolve it:

1. Open Start, search for Get Help, and launch it.
2. Search for Copilot connectivity troubleshooter.
3. Run the troubleshooter and apply any suggested remedies.
4. Reopen Copilot.

This checks for firewall rules and other connection blockers that can leave Copilot unable to load its content.^2^

3. Determine whether the failure is app-only

Open Copilot in Edge or Chrome using the same Microsoft account:

• Browser works: The problem is confined to the Windows app. Install pending Windows and Store updates:
  1. Settings → Windows Update → Check for updates.
  2. Install available updates and restart Windows.
  3. Open Microsoft Store → Library → Get updates.
  4. Apply any Copilot or Store update, then test again.^3^
• Browser is also blank: This points away from the installed app package and toward an account, network, or service path. Similar Windows 11 reports describe Copilot remaining blank after reinstallation and sometimes failing in browsers as well.^4^ Test another network or another Microsoft account, if available. If only the original account fails across both app and browser, report the issue through Get Help rather than reinstalling again.

4. Only if the entire window or display is visually corrupted

If other windows also appear blank or the Copilot window does not redraw properly, press:

Windows key + Ctrl + Shift + B

The screen should flicker or beep as Windows resets the graphics driver.^5^ Skip this if only Copilot’s content area is white while the rest of Windows displays normally.
