Overview
- Microsoft says Windows 11 versions 24H2 and 25H2 can be affected when updates released since August 2025 are installed.
- The problem appears mainly on PCs that allow multiple sign-in methods such as password alongside PIN or biometrics.
- The password option remains functional; hovering over the usual icon location reveals a clickable placeholder that opens the field.
- A permanent patch is in development, but Microsoft has not provided a timeframe, and the preview update is not installed automatically on all machines.
- User reports include cases in German-speaking regions, and KB5064081 has also been linked to display color shifts and blocked video playback.
