April updates released by Microsoft cause issues with Windows Hello

The issue affects both client (Windows 11 24H2) and server (Windows Server 2025) systems with cumulative update KB5055523 installed, but only occurs in specific situations.

Authentication failures occur on devices with Dynamic Root of Trust for Measurement (DRTM) or System Guard Secure Launch enabled prior to installing KB5055523.

“We’re aware of an edge case of Windows Hello issue affecting devices with specific security features enabled. After installing this update and performing a Push button reset or Reset this PC from Settings > System > Recovery and selecting Keep my Files and Local install, some users might be unable to login to their Windows services using Windows Hello facial recognition or PIN,” – Microsoft.

As a result, users might observe a Windows Hello Message saying “Something happened and your PIN isn’t available. Click to set up your PIN again” or “Sorry something went wrong with face setup”.

Since there is no fix for this issue yet, the company offers the following workarounds:

• To login using PIN, follow the Set my PIN prompt on the logon screen to re-enroll into Windows Hello; or 
• To use Face Logon, re-enroll in Windows Hello Facial recognition go to Settings > Accounts > Sign-in options > Facial recognition (Windows Hello), and select Set up. Follow the on-screen instructions.
