About this tag
Discussions on WindowsForum.com about low light recognition focus on a recent Windows Hello update that restricts facial recognition to well-lit environments. Previously, Windows Hello used infrared sensors to authenticate users in complete darkness, but the April 2025 update (KB5055523) now requires both IR and RGB cameras, preventing logins in low light. This change is a deliberate security enhancement, though it has caused frustration among users of Surface Laptops, Dell XPS, and other devices who relied on dark-room authentication. The threads explore the trade-off between security and convenience, with many seeking workarounds or clarification on Microsoft's policy shift.
