Microsoft today announced a new preview build for the Windows
Insiders and it comes with a revamped File Explorer that
features the highly anticipated dark theme. Microsoft says
that Dark Theme support for File Explorer is ready for the
next major release of Windows, codenamed Redstone 5.
In the latest Windows 10 Build 17733, the dark UI for File
Explorer is now live and it has been finalized for the general
public release. You would need to open Settings and
navigate to Personalization > Colors -> select the Dark
option under the “Choose your app mode” section to apply dark
theme in File Explorer.
Microsoft says that the dark theme in File Explorer was a
highly requested feature but Microsoft delayed it due to
“Here’s why: compared to modern parts of Windows, File Explorer
was a whole different beast. While dark mode can be applied
to modern XAML components in Windows quite easily, File
Explorer contains legacy UI frameworks which don’t plug into
that infrastructure automatically. With File Explorer, we were
literally breaking new ground to provide a dark theme to legacy
parts of the shell. We also needed to be careful to only change
File Explorer (and the Common File Dialog) and not change
common controls generally, which could break a lot of app
experiences (such as making dark text in an app unreadable),”
The dark theme in File Explorer was initially ugly but it has
evolved before the public. For example, Microsoft added grey
colour to areas like the view pane, adjusted the address bar
and ribbon colors.
For those unfamiliar, Windows 10 Redstone 5 is expected to
arrive in the month of October later this year.
