has sent out the latest Windows 10 19H1 branch preview to Windows Insider Program members. The update bumps the preview line to build to 18342. This is a solid feature expansion as it adds gaming improvements, a Chrome extension for Timeline, and support for Linux files to the Win10 experience.

If you don't know, is the current preview branch for the platform. Microsoft will finalize the build in March where it will officially become version 1903. Early in April, the company will start rolling out 19H1 to all users, where it will likely be called the April 2019 Update.

This latest update will appeal to Linux fans as they can now access files in a WSL distro on Windows 10. Linux files can be accessed via the command line \\wsl$\, which shows a list of running distros.

Elsewhere in Windows 10 Preview build 18342, Microsoft has improved gaming on the platform. Finally, the company has announced a new Chrome extension called Web Activities. This is a Windows Timeline integration that collects activities to place on Timeline.

“Just sign-in to the extension on your Chrome browser with your Microsoft account, visit a site in Chrome, then watch it appear on Timeline – and pick up where you left off. Your Chrome activities will also sync with Timeline on Android devices using the Microsoft Launcher app.”
