#Microsoft Linux

Microsoft has announced that the company will include an in-house custom-built Linux Kernel in Windows. This implementation is the first time that the Linux kernel will be included as a component in Windows to underpin the newest version of the Windows Subsystem for Linux (WSL) -- WSL2. Like with WSL1, WSL2 will not provide any userspace binaries, instead, the Microsoft kernel will interface with userspace selected by the user. The kernel will be based on version 4.19 initially which is the latest stable release of Linux. "This is the culmination of years of effort from the Linux Systems Group as well as multiple other teams across Microsoft. We are excited to be able to share the result and look forward to the new and interesting ways in which you will use WSL." As for security, the WSL kernel will be built using Microsoft's CI/CD systems and serviced through Windows Update that is transparent to the user.

Microsoft has announced to completely remove the Adobe Flash component from Windows through the KB4577586 "Update for Removal of Adobe Flash Player" starting June 2021.
