You will be asked a few questions. The installer script finds the current DPI scaling in Windows, you can set your own value if preferred:

 This will take a few minutes, please wait...

The installer will download and install the LxRunOffline distro manager and Windows Store Ubuntu image. Reference times will vary depending on system performance and the presence of antivirus software. A fast system with good Internet can finish in under 10 minutes.

   - xRDP Server listening on port 13399 and SSHd on port 13322.

   - Links for GUI and Console sessions have been placed on your desktop.

   - (Re)launch init from the Task Scheduler or by running the following command:
     schtasks /run /tn XFCE416
 
  XFCE416 Installation Complete!  GUI will start in a few seconds...

A fullscreen XFCE session will launch using your stored credentials.

Configure xWSL to start at boot (like a service, no console window)

• Right-click the task in Task Scheduler, click properties
• Click the checkbox for Run whether user is logged on or not and click OK
• Enter your Windows credentials when prompted

Reboot your PC when complete and xWSL will startup automatically.

Start/Stop Operation

• Reboot the instance (example with default distro name of 'xWSL'): schtasks /run /tn xWSL
• Terminate the instance: wslconfig /t xWSL

xWSL leverages Multicast DNS to lookup WSL2 instances

If your computer has virtualization support you can convert it to WSL2. xWSL is faster on WSL1, but WSL2 has additional capabilities.

Example of conversion to WSL2 on machine name "COMPY":

• Stop WSL on COMPY: wsl --shutdown
• Convert the instance to WSL2: wsl --set-version xWSL 2
• Restart xWSL Instance: schtasks /run /tn xWSL
• Edit the .RDP file to point at the WSL2 instance by adding -xWSL.local to the hostname, so for COMPY it would be: COMPY-xWSL.local:3399

Make it your own:

From a security standpoint, it would be best to fork this project so you (and only you) control the packages and files in the repository.

• Sign into GitHub and fork this project
• Edit xWSL.cmd. On line 2 you will see SET GITORG=DesktopECHO - Change DesktopECHO to the name of your own repository.
• Customize the script any way you like.
• Launch the script using your repository name: PowerShell -executionpolicy bypass -command "wget https://github.com/YOUR-REPO-NAME/xWSL/raw/master/xWSL.cmd -UseBasicParsing -OutFile xWSL.cmd ; .\xWSL.cmd"

Quirks / Limitations / Additional Info:

• RDP Sessions can be disconnected and will resume at your next login.
• When you log out of a desktop session, the entire xWSL instance is restarted, the equivalent of an instant clean-boot at every login.
• xWSL should work fine with an X Server instead of xRDP. The file /etc/profile.d/xWSL.sh contains WSL-centric environment variables that may need adjustment, such as LIBGL_ALWAYS_INDIRECT.
• WSL1 Doesn't work with PolicyKit. Enabled gksu for apps needing elevated rights (Synaptic, root console)
• Apt-fast added to improve download speed and reliability.
• Mozilla Seamonkey and Falkon (Chromium-based) browsers included. Current versions of Chrome / Firefox do not work in WSL1.
• Installed image consumes approximately 2.6 GB of disk space
• XFCE uses the Plata theme, Papirus icon theme and Windows fonts (Segoe UI / Cascadia Code)
• Uninstaller is located in the root of xWSL folder, 'Uninstall xWSL.cmd' - Make sure you 'Run As Administrator' to ensure removal of the scheduled task and firewall rules
