As part of the April 2019 Update development, Windows 10 build 18342 is now rolling out for devices enrolled in the Fast ring of the Windows Insider Program. This is the 23rd preview releasing to testers with several new improvements and a slew of fixes.

Windows 10 build 18342, according to Microsoft, is a small update that includes (unclear) improvements for the new “Windows gaming technology,” changes for the Windows Subsystem for Linux, Windows Sandbox, File Explorer, and more.

Here are all the features and changes coming to the next version of Windows 10:

File Explorer

Starting with this April 2019 Update, File Explorer now allows you to rename a file using a dot at the beginning of the name (for example, “.gitignore”).

Windows Subsystem for Linux

If you use Linux on Windows 10, you can now access the Linux files part of the Windows Subsystem for Linux environment.

The new files are accessible using command line or File Explorer. In order to access the files, you need to navigate to \\wsl$\distro_name, or see a list of running distributions by navigating to \\wsl$.

Also, build 18342 introduces improvements for the wsl.exe command line interface. For instance, you can now import and export distros, and you can now consolidate existing features from wslconfig.exe, such as list distros and setting defaults.

Windows Sandbox

The Windows Sandbox experience now captures hotkeys in full screen, and it brings supports configuration files.

Using these files allows you to configure some aspects of the experience, including vGPU, networking and shared folders.


Starting with build 18342, Microsoft continues to mention improvements for its new “Windows gaming technology,” but the specific details are still unknown.

Additional improvements

Alongside the new features and changes, Windows 10 build 18342 ships with other minor improvements. For example, the name of the “Windows Light” theme to now be “Windows (light)”, when using the Magnifier with larger pointers, it pans smoothly as the pointers change shape, and the new tamper protection setting available in the Windows Security app that protects your device is now enabled by default for Insider Preview builds.

Microsoft is listing the complete set of improvements, fixes, and known issues for Windows 10 Insider Preview build 18342 at the Windows Blog.
