Microsoft finishes turning File Explorer dark in latest Windows update

Add as a preferred source on Google

If you typically work in low ambient lighting conditions, Microsoft’s latest Windows Insider Preview build will help ease eye strain. The most notable feature of Windows Insider Preview Build 17733 is a new dark mode for the Windows File Explorer, which replaces the typical white background of the File Explorer window for a black one.

“With Build 17666 we started our journey bringing dark theme to File Explorer,” Microsoft said in a blog post detailing the new features of the software release. “Today’s build marks the turning point where we’ve finished what we set out to do for this release.”

The dark theme for File Explorer was initially introduced in May, and it appears that Microsoft has completed its work on this feature. General users of Windows 10 who are not part of Microsoft’s Windows Insider program will get to experience this feature this fall when Microsoft releases its Windows 10 Redstone 5 update.

The latest Insider Preview build is available for testers in the Windows Insider program in the Fast ring. In addition to the dark mode, the build also delivers a number of bug fixes and some general improvements for Narrator. This release doesn’t include much in the way of new features.

As with the prior release, Microsoft also outlined a number of known bugs in this release. If you’re running Windows 10 in S Mode, the version of Microsoft Office downloaded from the Windows Store may not run properly, and Microsoft recommends that you can work around this glitch by uninstalling and reinstalling that software package. Like the previous Windows Insider Preview, users of Windows Mixed Reality headsets may need to repair their controllers.

Microsoft isn’t the only one to focus on launching a dark mode. At its developer conference earlier this year, rival Apple introduced a system-wide dark mode that will be part of the new Mojave operating system for Macs. Both Mojave and Microsoft’s Redstone 5 update for Windows 10 will be available for consumers to download this fall. Be sure to check out our guide on how to apply a dark theme for File Explorer and Windows 10 if you’re part of the Windows Insider program today.

Microsoft Edge’s latest Chrome-inspired feature could tame your tab chaos
A small change being tested in Edge Canary could make managing a messy collection of vertical tabs considerably easier.
Microsoft Edge illustration official

Microsoft Edge and Google Chrome have been borrowing ideas from each other for years, and Microsoft appears to have spotted another Chrome feature worth bringing over. As Windows Report has spotted, a new Tab Groups button is starting to appear in Edge Canary for people using vertical tabs. Instead of hunting through your open tabs to find a particular group, the new button provides one place to see the groups you've already created or start a new one.

It isn't an entirely new feature for Edge. Microsoft's browser has supported Tab Groups for some time, including when using vertical tabs. What's changing is how easy those groups are to get to. That might sound like a tiny interface tweak, but anyone who routinely ends up with dozens of tabs open will probably understand why it could be useful.
