Cannot open copilot

Install Microsoft Copilot from the Microsoft Store, then open it from Start and sign in with your personal Microsoft account; Copilot may not appear in the installed-app list if the standalone app has not yet been installed. ^1^

Install and open Copilot

1. Open Microsoft Store from the Windows 11 Start menu.
2. Search for Microsoft Copilot.
3. Select Get or Install.
4. When installation finishes, select Open.
5. Sign in with your usual personal Microsoft account.
6. To keep it accessible, open Start, search for Copilot, right-click it, and select Pin to taskbar.

You can also open the official Store listing directly:

After installation, Copilot can be launched from Start, the taskbar, the Copilot key on supported keyboards, or Windows key + C. ^1^

If Copilot is installed but will not open

Reinstall the app:

1. Go to Settings → Apps → Installed apps.
2. Search for Copilot.
3. Select the … menu beside it, then Uninstall.
4. Restart Windows.
5. Reinstall Copilot from the Microsoft Store listing above.

Microsoft documents this uninstall-and-reinstall path specifically for Copilot on Windows 11. ^1^

If the Store installation fails, check Settings → System → About → Windows specifications. The Copilot app requires Windows 11 version 22H2 or later. Also run Settings → Windows Update → Check for updates, install available updates, and restart the PC. ^2^

If “does not show in my apps” means Word, Excel, or PowerPoint

The Copilot entry point in current Microsoft 365 apps is normally in the lower-right corner of the open document, workbook, or presentation rather than only on the ribbon. Its availability also depends on the Microsoft 365 subscription and Copilot entitlement. ^3^

If it is absent there:

1. Open Get Help from Start.
2. Search for Copilot License Troubleshooter.
3. Run the troubleshooter and apply its recommended correction. ^4^

This license check is only needed for Copilot inside Microsoft 365 applications; it is not the first step for installing the standalone Windows app.
