Windows Hello, a feature in Windows 10 that allows for face unlock functionality, has encountered a bug following the latest update (Build 26100.3775) released on April 8th. This bug affects some users' ability to use face unlock and PIN logins after resetting their PC while retaining local files and enabling System Guard Secure Launch or DRTM. Although users should still be able to access their PCs using their Windows password, the issue is concerning for those who rely on Windows Hello. The bug is considered an edge case, impacting only a limited number of users, and regaining access is possible with a password manager or IT support. Users can re-establish Windows Hello by performing a new face scan once they regain access.
