An application or feature powered by Windows Copilot to assist users with tasks and productivity
If Microsoft Copilot works in Bing but the Windows Copilot app gets stuck at sign-in, the supported checks are:
- Use a personal Microsoft account in the Windows Copilot app. The Windows app requires a personal Microsoft account, not a work account.
- If the app is using the wrong signed-in profile, switch accounts. Copilot can behave differently depending on whether the session is using a personal Microsoft account or a work/school account.
- If the app still does not sign in, repair or reset the app:
- Open Settings > Apps > Installed apps
- Find Microsoft Copilot
- Open Advanced options
- Try Repair first
- If that does not help, use Reset
- If the issue started after an update, uninstall and reinstall the Microsoft Copilot app from Microsoft Store.
- If the app is opening a web-based sign-in flow and stays stuck there, make sure the browser session is not blocked by cookie settings. For Microsoft 365 web apps, license validation requires third-party cookies. In Edge: Settings and More > Settings > Cookies and site permissions > Manage and delete cookies and site data > ensure Block third-party cookies is Off.
- If signed in with a work or school account, switch to the correct account type for the app experience being used. The consumer Copilot app and Copilot for work use different account experiences.
If the app remains stuck after these steps, use the web experience instead while troubleshooting:
- Consumer Copilot: copilot.com
- Microsoft 365 Copilot app on web: https://microsoft365.com
