We are stuck in an endless sign-in loop on a microsoft device. Also did the repair (troubleshoot), seemed to have done the process but still unable to log in - comes back to the sign in page.

Microsoft account log-in successfully on another device, but we need to log in to Devise Microsoft Surface.

    Since the Microsoft account works on another device, the account itself is likely not the blocker. For the Surface sign-in loop, use this order:

    1. Restart the Surface
      • On the sign-in screen, select Power > Restart.
      • If updates are offered, use Update and restart.
      • This can clear temporary sign-in errors.
    2. Check network access from the lock screen
      • On the lock screen, select Network and confirm the Surface is connected to the internet.
      • If Wi-Fi is weak or unstable, connect directly with Ethernet if available.
      • Some sign-in scenarios require an internet connection.
    3. Try Safe Mode with Networking
      • On the sign-in screen, hold Shift and select Power > Restart.
      • Go to Troubleshoot > Advanced options > Startup Settings > Restart.
      • After restart, select 5 or press F5 for Safe Mode with Networking.
      • Important: Safe Mode sign-in works only with a password. PIN and biometric sign-in are unavailable there.
      • If sign-in works in Safe Mode, that indicates the basic drivers and default settings were not causing the problem.
    4. Try another account on the Surface if one exists
      • On the sign-in screen, select another account from the lower-left list.
      • If needed, select Other user and enter that account’s credentials.
      • If sign-in succeeds with another account, check for Windows updates and review the existing accounts. Admin rights are needed for account review.
    5. If the issue is specific to Microsoft account sign-in flows, use the Microsoft sign-in helper
      • The official sign-in helper is recommended for Microsoft account sign-in problems: Sign-in helper
    6. If the Surface still cannot be used, use Surface support options
      • Open the Surface app, describe the problem, and select Get Help.
      • If the device cannot be used normally, open Get Help for other support online.
      • For a work or school-managed Surface, contact the organization’s IT helpdesk or admin.

    A sign-in loop that survives the built-in troubleshooter usually points to a corrupted user profile or a stuck credential/Hello cache rather than a network or account problem — especially since the same Microsoft account works fine elsewhere.

    Boot into Safe Mode (hold Shift and click Restart from the sign-in screen's power button, then Troubleshoot > Advanced options > Startup Settings > Restart > press 4). If you can sign in fine in Safe Mode, the loop is caused by a startup app or driver, not the profile itself — skip to the SFC/DISM step.

    Force two failed boots in a row (hold power button to cut power during startup) to trigger Automatic Repair, then choose Troubleshoot > Advanced options > Command Prompt. Run: DISM /Online /Cleanup-Image /RestoreHealth, then sfc /scannow.

    If the loop happens right after PIN entry, the Windows Hello credential cache may be corrupt. On the sign-in screen, click 'Sign-in options' and choose the password icon instead of PIN. If password gets you in, delete and recreate the PIN afterward in Settings > Accounts > Sign-in options.

    From that same WinRE Command Prompt, run 'dir C:\Users' to find your profile folder, then rename it (e.g., ren C:\Users\YourName YourName.old). Windows will build a fresh profile on next sign-in and pull your account settings from the cloud again, leaving old files recoverable in the renamed folder.

    In the WinRE Command Prompt, run 'net user tempadmin /add' then 'net localgroup administrators tempadmin /add'. Reboot and sign in locally to confirm whether you can at least get a working desktop, which tells you the problem is with your Microsoft account profile specifically, not the OS install.
