The screenshots match two different Windows sign-in conditions:
- “The referenced account is currently locked out” This is consistent with Windows account lockout policy after repeated failed sign-in attempts.
- “Something went wrong and your PIN isn’t available. Restart your device to see if that fixes the problem.” This indicates the PIN sign-in path is unavailable, so a different sign-in method is needed until PIN works again.
Since a full shutdown and startup helps, but Restart does not, use this path:
- On the sign-in screen, select Sign-in options.
- Choose the password option instead of PIN, if available.
- If the account is locked, leave the PC powered on at the sign-in screen and wait for the lockout period to expire before trying again.
- If PIN remains unavailable after sign-in, reset it from Settings > Accounts > Sign-in options using I forgot my PIN.
- If the device is affected by the recent Microsoft account sign-in issue on Windows 11 24H2 or 25H2, install the latest Windows updates. This issue was resolved by updates released March 21, 2026 (KB5085516) and later.
- If the device is on an update released before that fix, restart the device while it remains connected to the internet. If it was restarted without internet, restart it again with active internet connectivity.
Important details:
- The Microsoft account sign-in issue affects Microsoft account sign-ins, not Entra ID business sign-ins.
- New Windows 11 devices have secure-by-default account lockout settings: 10 failed sign-in attempts, 10-minute lockout duration, and 10 minutes to reset the lockout counter.
- For built-in local Administrator account lockout, Microsoft’s baseline recommendation is 10/10/10. That lockout applies to network logons such as RDP; console logons are still allowed during the lockout period.
If another account on the PC is available, sign in with that account and use it to check Settings > Windows Update and install the latest updates first.
