In the latest chapter of Windows update woes, users are facing a frustrating new bug linked to the recent security patch, KB5055523. This issue, which has emerged following the April 2025 update, is particularly affecting those operating on Windows 11 24H2 and Windows Server 2025. The glitch manifests in a specific scenario involving users with Dynamic Root of Trust for Measurement (DRTM) or System Guard Secure Launch enabled, who opt for the “Reset this PC” feature while choosing to “Keep my Files.”
Access Denied
After executing the reset, many users find themselves unexpectedly locked out of their devices. Instead of the familiar face or PIN-based login, they encounter error messages such as “Something happened, and your PIN isn’t available” or “Sorry, something went wrong with face setup.” This situation can understandably lead to a sense of panic among users who rely on these features for seamless access to their accounts.
As a temporary solution, Microsoft has provided workarounds for those affected by the Windows Hello bug. Users can regain access to their PIN by following the “Set my PIN” prompt on the login screen, allowing them to re-enroll in Windows Hello. For those who prefer facial recognition, the process requires navigating to Settings > Accounts > Sign-in options > Facial recognition to set it up anew.
While these workarounds offer a path back into accounts, the inability to log in with a PIN may still leave some users feeling anxious. This is not the only challenge associated with KB5055523; Microsoft has also addressed a separate issue where a Windows update bug led to the uninstallation of Copilot on certain PCs, a glitch that many users found to be one of the more amusing bugs in recent memory.
Additionally, this Windows Hello bug coincides with a new safeguard hold affecting devices that utilize SenseShield’s sprotect.sys driver, which has been causing blue or black screen errors. As users navigate these hurdles, the hope remains for an official fix to be released soon. In the meantime, while the workaround may be inconvenient, it does provide a lifeline for those locked out of their accounts.
