I upgraded to wsl2 today, it runs a lightweight Hyper-V VM with a real Linux kernel so there is no syscall translation layer needed, all programs work perfectly now, htop for example, doesn't work in wsl 1 before.
The upgrade is straight forward: wsl –set-version Ubuntu 2, it took a while to upgrade, I guess it copies large amount files to a new partition, I find turning off real time virus and thread protection in windows 10 could speed thing up, and wsl -l -v could list all workloads in the system.
Files under /mnt/c, mnt/d etc, are fully maintained by use of a filesystem bridge using the 9P protocol.
