Where exactly is wsl.exe now?

[blakeduffey]

Corporate has rolled out a new initiative and it may be breaking wsl-vpnkit.

I see C:\WINDOWS\system32\wsl.exe

I also see C:\Program Files\WSL\wsl.exe

Event log says the former is being invoked, but the latter is version 2.0

Can someone explain what these various executables are? May be useful in troubleshooting.
