Microsoft confirmed in the health dashboard that after upgrading to Windows
11 22H2, there may be some abnormal problems with the Windows Hello biometric verification system. This issue should theoretically affect many users, since Windows Hello also includes PIN verification, and most users may already have a PIN configured. According to Microsoft’s instructions, before upgrading to the new version, if the user has configured any Windows Hello authentication method, it will not be available after the upgrade.
At this time, since the fingerprint, face, iris or PIN cannot be used when logging in to the system, the system will automatically return to the traditional password login and will not shut out the user. If the user did not enable Windows Hello before the upgrade, they can continue to use the password to log in, and the PIN configuration after the upgrade can be used normally. At present, Microsoft has launched the KB5017389 update to solve this problem. The safeguard hold is estimated to be removed in mid-October 2022.
