The Core of the Problem: Why Windows Hello Stops Working After a Reset​

The Windows Hello malfunction centers on recent changes introduced by Microsoft's KB5055523 update, released as part of the April 2025 patch cycle. While this update was designed to enhance security and system integrity, it unexpectedly disables Windows Hello login capabilities — specifically facial recognition and PIN sign-in methods — for a subset of Windows 11 users.
The issue manifests under a very narrow set of conditions:

• Devices running Windows 11 24H2 or Windows Server 2025
• After installing the KB5055523 update
• When performing a "Push button reset" or selecting "Reset this PC" in Settings > System > Recovery with the option “Keep my Files” and choose Local install
• On devices having advanced security features enabled, particularly Dynamic Root of Trust for Measurement (DRTM) or System Guard Secure Launch

Only users who meet all these criteria encounter the problem, making it an "edge case" rather than a widespread failure. Still, for those affected, it can be a major barrier to accessing their computers easily and securely through the fast, passwordless Windows Hello system.

Understanding the Technical Cause: Security Feature Conflicts​

Windows Hello’s biometric and PIN authentication relies heavily on deep integration with security features that protect the boot process and system integrity. Two key technologies involved here are:

• Dynamic Root of Trust for Measurement (DRTM): Ensures the critical parts of a system’s boot process are measured and verified dynamically to prevent tampering.
• System Guard Secure Launch: A security extension designed to prevent unauthorized modifications during system startup for stronger firmware-level protection.

The KB5055523 update modifies how these features interact during and after a system reset, particularly when users preserve files but reinstall locally. This leads to a misalignment between the reset environment and the expectations of Windows Hello’s authentication mechanisms.
What this means in practice is that Windows Hello’s biometric and PIN credentials become temporarily unusable. The system displays error messages like:

• “Something happened and your PIN isn’t available. Click to set up your PIN again.”
• “Sorry, something went wrong with face setup.”

Users cannot authenticate using facial recognition or their PIN until they undergo a specific re-enrollment process.

User Experience: Facing the Login Roadblock​

For IT professionals and ordinary users alike, the disruption to Windows Hello authentication translates into several immediate problems:

• Initial lockout from biometric and PIN access after a reset, especially problematic for enterprise settings relying on quick and secure authentication.
• Inconvenience and frustration as the seamless Windows Hello login experience devolves into additional setup steps.
• Potential confusion for less tech-savvy users who rely heavily on facial recognition as their primary sign-in method.

Despite this, Microsoft has ensured that traditional password login remains functional, which acts as a fallback for regaining access to the device. Users can enter their Microsoft account or local password to sign in, allowing recovery actions to begin.

Workarounds: How to Restore Windows Hello Functionality​

While a permanent patch from Microsoft is pending, there are practical steps users can take to resume biometric or PIN access:

For PIN Issues:​

• At the login screen, when prompted with the “PIN isn’t available” message, follow the notifications to reset or set up a new PIN.
• This re-enrollment resets the PIN authentication system, restoring its functionality.

For Facial Recognition Problems:​

• After logging in with your password, navigate to:
  Settings > Accounts > Sign-in options > Facial recognition (Windows Hello)
• Select the option to “Set up” again and follow the on-screen instructions to re-register your face.
• This process effectively refreshes the biometric credentials.

Additional Tips:​

• Avoid performing a reset with “Keep my Files” enabled if possible, until the patch is released.
• If comfortable, temporarily disable System Guard Secure Launch or DRTM to mitigate the issue, though this reduces security protections.
• Some users report adjustments in Device Manager, such as disabling the RGB camera and relying solely on the infrared sensor, might help in certain cases, but this is not an officially recommended or guaranteed fix.

The Bigger Picture: Windows Hello and the Passwordless Future​

Windows Hello was launched as a cornerstone technology aimed at moving users away from passwords and towards faster, more secure methods like biometrics and PINs. Microsoft’s vision of a passwordless future hinges on such innovations providing seamless yet robust authentication.
However, bugs like this Windows 11 reset issue spark valid questions:

• Is the passwordless future ready for prime time?
• Can biometric and PIN systems maintain reliability amidst complex security feature interactions?
• What contingency plans must users and organizations adopt?

Crucially, Windows Hello requires setting up a PIN during initial configuration, acting as a safeguard in case biometric options fail. This layered authentication approach highlights Microsoft’s awareness of the tech’s limitations and challenges.
Ultimately, this incident demonstrates the balance Microsoft must strike: enforcing tighter security without compromising user convenience. Until Windows Hello achieves near-perfect reliability, fallback options and user education remain essential.
