There are a lot of information on how to enable/install WSL 2 and setup XWin type of configuration so this how-to will just focus on the important part.
Note: I like XWin but you can also use XRdp instead of XWin https://medium.com/@apph/desktop-gui-using-wsl2-xrdp-a870a2d32df8
Assumption:
. You already have WSL 2 enabled and installed if not here is one of them.
https://docs.microsoft.com/en-us/windows/wsl/install-win10
# PowerShell command to manually enable VM feature for wsl 2
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
. You already install some form of XWin server but if not here is one of them.
https://sourceforge.net/projects/vcxsrv/
. You already install one of the Linux distribution if not here is one of them

At this point, you will have a running Linux distribution in WSL 2.
Here are a few things you need to check before you attempt to run "xterm &" to show on your XWin server.
WSL things:
# see what was in WSL 2
wsl -l -v
# download wsl 2 Linux kernel update and install before you do the next line
https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi
# enable VM support
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
# set WSL 2 as your default
wsl --set-default-version 2
# set your Debian distribution to use WSL 2
wsl --set-version Debian 2
Linux distribution things:
# run these commands to make sure your Debian distribution is clean and up to date
sudo apt-get clean && sudo apt-get autoremove && sudo apt-get update --fix-missing && sudo apt-get upgrade --fix-missing
# Set your WSL 2 host as your Xwin host IP by add these two lines to your .bashrc
#export DISPLAY=:0 # in WSL 1
#export DISPLAY=$(awk '/nameserver / {print $2; exit}' /etc/resolv.conf 2>/dev/null):0 # in WSL 2
#export LIBGL_ALWAYS_INDIRECT=1
export DISPLAY="`grep nameserver /etc/resolv.conf | sed 's/nameserver //'`:0"
echo $DISPLAY
# MOST important part to make "xterm &" to display on your XWin server by adding a firewall rule on your Windows 10 PC to allow loop back from your Linux distribution from WSL 2
# Make sure you firewall rule allow VcXSrv on your private or/and public network
###### run this command in PowerShell with administrator permission
New-NetFirewallRule -DisplayName "WSL" -Direction Inbound -InterfaceAlias "vEthernet (WSL)" -Action Allow
######
That's it.
Happy Linux on Windows 10!
