First, a new logo for the Windows Subsystem for Linux, with the famous Linux Penguin symbol. Elsewhere, Microsoft allows hardware performance counters when supported by the device. Of course, this version also overwrites the Linux kernel, moving it to version 5.10.74.3.

Microsoft Store app

Last month, Microsoft revealed that it will update WSL separately from the larger Windows platform. This means that the subsystem is now available as a standalone app on the Microsoft Store. Microsoft says the Windows 11 WSL app will be managed through the Store. Users will receive updates separately from Windows. Essentially, this means that updates will occur between major Windows feature upgrades.

Depending on the company, WSL users can “Get the latest WSL updates and features faster, and without having to change your version of Windows.” ”

Tip of the day: Did you know that Task Manager allows you to set CPU affinity to retrieve certain resources from running applications and give selected applications higher priority. Our tutorial shows how you can use this useful feature.
