Windows Subsystem for Linux (WSL) is an extremely useful compatibility layer that enables users to run Linux binaries natively on supported Windows devices, without having to download dedicated virtual machines (VMs). Microsoft previously allowed people to enable WSL from the "Turn Windows Features on or off" dialog box, but last month, it began offering installations via the Microsoft Store as well. Today, the company has rolled out pre-release version 0.50.2 of WSL.
The change log for Windows Subsystem for Linux Preview version 0.50.2 can be seen here. It packs a new logo featuring a penguin (screenshot above) instead of the generic running application graphic and also features version 5.10.74.3 of the Linux kernel. The full change log can be seen below:

While Microsoft engineer Craig Loewen has posted an image of an updated Microsoft Store listing for Windows Subsystem for Linux Preview on his Twitter, we have not received the update on any of our devices running Windows 10 and Windows 11 yet, indicating a staggered rollout.
