Answer 1

1st step - Disable Windows path on WSL

Option A: Add to wsl.conf (after Build 17093)

sudo nano /etc/wsl.conf

Then add

[interop]
appendWindowsPath = false

then Ctrl+S then Ctrl+X then exit.

Option B: remove paths on runtime

Add the following code to .bashrc

PATH=$(/usr/bin/printenv PATH | /usr/bin/perl -ne 'print join(":", grep { !/\/mnt\/[a-z]/ } split(/:/));')

Alternative (run once!):

echo "export PATH=`echo $PATH | tr ':' '\n' | grep -v /mnt/ | tr '\n' ':'`" >> ~/.bashrc

Alternative 2

Just add export PATH="$PATH:/usr/bin" to the end of ~/.bashrc, so that usr/bin takes precedence over windows' apps. Probably not a good option.

Option C:

Edit Windows Registry. It is currently not recommended.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Lxss\{GUID}\Flags

Change Flags from 7 to 5 in order to exclude the WSL_DISTRIBUTION_FLAGS_APPEND_NT_PATH enum.

2nd step - Restart WSL

Option A:

Simple reenter WSL and test:

echo $PATH

Option B:

Run at PowerShell as Admin:

Restart-Service LxssManager

Option C:

Terminating WSL from PowerShell as Admin using

wslconfig /t Ubuntu

Adapt was your need, Ubuntu-18.04 in my case
