Contrary to what some people might think, Windows 10 and Linux are not sworn enemies. Sure, there is a big difference between proprietary and open source software, but for people who run both operating systems, Microsoft is adding a neat feature to Windows 10—Linux file integration into File Explorer (see image above).
Microsoft is essentially building on its plan to jam a full Linux kernel in Windows 10, as it previously announced. Users have been able to access Linux files in Explorer since the May 2019 update (Windows 10 version 1903), but the feature being tested right now adds a Linux icon (Tux) in the left-hand navigation pane of Explorer if you have Windows Subsytem for Linux, or WSL, installed.
It's a subtle change, and also a welcome one. Previously, users would have to open up their Linux distro, make sure the current folder was in their Linux home directory, then type 'explorer.exe' to open a File Explorer window containing their Linux files.
It's not clear when 20H1 will roll out, other than sometime in the first half of the year, barring a delay. Microsoft has committed to releasing two major feature updates to Windows 10 each year, in addition to the cumulative security updates that arrive on Patch Tuesday—the second Tuesday of every month.
