Microsoft WSL2 Quick Trobleshooting

Prerequisites:

If you enable Windows Subsystem for Linux, you must enable Hyper-V and Virtual Machine  Platform feature as well. I'm not sure you need both of them, but it works for me. Otherwise you can't upgrade you Linux distro's to WSL2.

WslRegisterDistribution failed with error 0x8007019e

When you get this message, make sure you default version of WSL set to 1.
wsl --set-default_version 1
and try again
After succesful installation, you can upgrade you disto to version 2:
wsl --list --verbose
wsl --set-version <YouDistribution> 2
