Microsoft is working on enhancing the dark mode in Windows 11, with Marcus Ash, the head of Windows Design and Research, indicating efforts to expand the dark theme across more areas of the operating system. Improvements are being made to legacy system panels and dialogs to enhance consistency, although no specific timeline for updates, including for Regedit, has been provided. Additionally, Microsoft is responding to user feedback by refining the user experience, which includes plans to improve the file explorer and reintroduce taskbar customization options. Currently, dark mode is only partially integrated, with key features like File Properties in File Explorer, Regedit, and Disk Management lacking support.
