install xwindows and xfce4 on Windows 10 + Ubuntu (creators version)

However, you can install graphical Linux applications and run these under WSL if you have an X server like VcXsrv or Xming, on your Windows machine.

a bit from the above link

1 sudo apt install xfce4

Next, you will need to modify the .bashrc file. There are a few text editors that work under WSL. I suggest to use vim or nano, e.g.:

1 cd ~
2 nano .bashrc

The second command from above will open .bashrc in nano and you can scroll to the end of the file and write:

1 export DISPLAY=:0.0

Save the modified file by pressing CTRL+X and answering Y when asked if you want to save the file. Close and restart the console window.
Next, you will need to install an X server for Windows. I suggest VcXsrv which works well with WSL. Download and start the installer, you can safely accept the default settings.
