Overview

• Screenshots shared by Phantomofearth show file operation dialogs in build 26100.5061 adopting a dark theme for the first time.
• The new UI elements remain hidden behind flags, display unfinished styling and exhibit glitches such as light-colored buttons.
• Microsoft has not formally confirmed the dark-mode updates and is expected to refine them before any official rollout.
• This marks the first visible progress on theming legacy Windows UI surfaces that have remained in light mode since 2016.
• Industry observers predict a polished, system-wide dark mode could arrive with the 25H2 update in late 2025.
