Microsoft is at last addressing one of Windows 11’s most persistent complaints. 3Marcus Ash, the head of Windows Design and Research, has provided a much needed update on Windows 11’s dark mode, which to this day is still incomplete. His confirmation that the company is working to bring dark theme into older system panels and dialogs signals a long overdue push toward visual consistency. But with no firm timeline and dozens of legacy tools still stuck in blinding white, the question remains: how much longer will users have to wait?
What Microsoft’s Design Chief Actually Said
The update came straight from the top of Windows design. 7In a response to Windows Central senior editor Zac Bowden on X, Marcus Ash offered a surprisingly transparent update on Windows 11’s dark mode.
6 “We are pushing to get our tools/techniques to the point where we can get dark theme into more areas across Windows,” Ash says. 6 “As we make progress in various legacy system panels/dialogs, we will keep improving consistency.”
When asked specifically about the Registry Editor, Ash was blunt. 7“No timelines to commit to yet for Regedit,” said Ash on X.
7 It’s worth mentioning that a true dark mode was not mentioned in Microsoft’s recently revealed, surprisingly comprehensive plan to improve Windows 11 based on user feedback. That detail alone tells you this effort is still in early stages.

A Decade of Broken Promises on Dark Mode
To understand why this update matters, you need to look at the timeline. 21In 2016, Microsoft officially added a dark mode toggle, which added dark mode to the File Explorer and context menus. 21However, this work was very much surface-level. Although the File Explorer and context menus finally had dark mode, it was very easy to encounter an area of the UI that didn’t support it.
That was nearly ten years ago. 3It’s good to see Microsoft once again working on improving dark mode in Windows, after basically neglecting it for almost a decade. Windows’ dark mode first debuted in 2016, and was rarely updated until just last year.
Here is a quick look at the history:
| Year | What Happened |
|---|---|
| 2016 | Dark mode toggle introduced in Windows 10 Anniversary Update |
| 2018 | File Explorer dark mode added in Windows 10 version 1809 |
| 2021 | Windows 11 launched with Fluent Design but incomplete dark theme |
| 2025 | Microsoft began updating File Explorer dialogs for dark mode |
| 2026 | Marcus Ash confirms ongoing work on legacy UI dark mode expansion |
21 When you take a look at macOS, iOS, iPadOS, and Android, these platforms include a consistent and complete system wide dark mode. When dark mode is enabled, it is rare to come across an area of the system UI that isn’t themed correctly. Windows stands alone among major operating systems with this level of inconsistency.
Which Windows 11 Tools Still Lack Dark Mode
The list of holdouts is surprisingly long for an operating system that has been around since 2021. 6There are a number of legacy interfaces littered across Windows 11 that still don’t support dark mode. File Properties in File Explorer is just one example, but Regedit, Run, Device Manager, Disk Management, and many more old school Windows control panels and applets are still dark mode-less.
Key Windows 11 areas still missing dark mode support:
- File Properties dialogs
- Registry Editor (Regedit)
- Run dialog box
- Device Manager
- Disk Management
- Control Panel applets
- Archive extraction windows
- Folder Options dialog
6 Microsoft is currently focused on improving dark mode in File Explorer. Just recently, it shipped dark mode support for interfaces like file copy and deletion popups, but File Properties, archive extraction, and others are still missing dark mode. 4 The February 2026 preview documentation says File Explorer’s key actions, progress bars, chart views, and multiple confirmation and error dialogs were refreshed to align with the dark theme. That is real progress. But it only covers part of the problem.
Why Fixing Legacy Dark Mode Is So Difficult
The technical challenge behind this goes deeper than most users realize. 2Legacy Windows components are often tied to older control panels, dialogs, MMC snap-ins, and system tools that were not originally designed with modern theming in mind. Extending dark mode to those areas is usually more complicated than changing the main Settings app or File Explorer.
1 Windows 11 features a mix of modern and legacy interface components. Older tools were created using frameworks that don’t automatically adopt newer theming systems. Some of these tools date back to the Windows XP era and even earlier.
This is not just a visual issue. 4Dark mode remains one of the most symbolic quality-of-life issues in Windows 11: it is not just about aesthetics, but about whether the platform feels coherent.
4 When a user sees a bright white copy dialog in the middle of an otherwise dark system, the impression is not merely “a UI bug”; it is the OS forgot its own rules. That reaction is exactly why dark mode has become a lightning rod for Windows criticism.
What Users Can Do Right Now
If you rely on dark mode daily, there are a few things to keep in mind while you wait for Microsoft to catch up.
1 To reduce visual disruption use the system dark mode setting in Settings to enable supported areas. Navigate to **Settings > Personalization > Colors** and select Dark under “Choose your mode.” 1 At this time, there is no supported way to enforce full dark mode across all legacy Windows components. Third-party tools exist, but they come with risks and are not officially backed by Microsoft.
Pro tip: 1Check for updates regularly, as improvements are gradually rolled out. Microsoft is shipping dark mode fixes through cumulative and preview updates, so staying current is the best way to get new theming improvements as they arrive.
17 Microsoft is also bringing in a useful improvement to enable Windows 11 users to more easily access dark mode. A new option to turn on dark mode or switch it off in the Quick Settings menu accessed via the taskbar has been spotted. There’s a new dark mode toggle in the Energy Saver panel, although this is still in testing for now.
The fact that Microsoft is finally talking openly about dark mode gives hope, but hope alone does not fix a system tool that blinds you at 2 AM. 4Marcus Ash’s comments are important not because they announce a finished feature, but because they reveal the company is treating theme consistency as a genuine engineering roadmap rather than a side quest. For the millions of Windows 11 users who work, create, and browse in dark mode every single day, this update is personal. It is about feeling like the operating system respects your choice from corner to corner.
