Windows Subsystem for Linux 0.65.1 is now live for all Insiders

A Microsoft Store listing for Windows Subsystem for Linux Preview

Windows Subsystem for Linux (WSL) is a powerful piece of software wizardry that allows users to run GNU/Linux environments directly in Windows without requiring virtual machines (VMs) or dual-boot configurations. Available for both Windows 10 and Windows 11, it's a very handy utility, especially for cross-platform development and testing. Microsoft regularly updates WSL with new features and capabilities. Today, it has announced WSL version 0.65.1 for Insiders.

As spotted by Windows Central, Microsoft's Manager of the Linux on Windows team Ben Hillis has confirmed that WSL 0.65.1 is available for all Windows Insiders, regardless of the release channel they are currently on. The idea is to cast a wide net for feedback by making it available for all Insiders and then use that feedback to determine whether the release is fit for general availability:

For WSL 0.65.1 we are trying something new! The build will be first available to Windows Insiders (all rings) first, then rolled out to everybody once we get positive signals on release quality.https://t.co/Sr087lHOq8
