The latest version of Windows 10 for insiders (20211) received another update to the WSL 2 subsystem (Windows Subsystem for Linux). Now, using console commands, without additional software, you can mount partitions (or entire disks) in the WSL subsystem, and this file system will be available to all of Windows.
Now there is no need for third-party software to mount ext4; it also says that other filesystems can be mounted. So now both systems can see each other for dual-butchers.
