Tip: Ensure VirtualBox Guest Additions are installed in the VM and nested paging is enabled.

Run any Windows App seamlessly on Linux! Just click on the File and choose "open with Windows" or "Always open with Windows"!

Windows Subsystem for Linux (WSL) BUT the other way around. Just like the name would suggest...

Important: Global Usage and Password File

• If you want to use windows.sh globally (from anywhere), the installer will create a symlink in /usr/bin pointing to the script in your project directory. Do not move or rename the project folder after installation unless you re-run the installer or recreate the symlink.
• The password file (vm_password.txt) is always read from the project directory, not from your current working directory.
• If you move the project folder, you must re-run the installer to update the symlink.

This works very well using "tiny11" from NTDEV or the "Superlite compact" version of Windows. These very small Windows installations that have removed some features.

No need to worry anymore that "this one tool for work" doesn't run on your Linux Machine! Now it will, just like if it was a native app… and this without many resources wasted or a complicated setup! Also, thanks to snapshots, you can easily revert any changes and startup the VM after a reboot extremely quickly!

I tested this using Xubuntu & Kubuntu 20.04, but it should work on any Linux system. The installation script automatically detects and supports:

• Arch-based systems (CachyOS, Manjaro, etc.) - uses pacman
• Debian-based systems (Ubuntu, etc.) - uses apt
• Fedora-based systems - uses dnf

For games, I still use Steams Proton. But for Business apps, I just use this setup.

Because it's a very small VM (iso install size without software is about 3.7 GB ("tiny10 23h1 x64")) you can just sync/move it between your Linux Computers without any additional setup or special config!

Requirements:

Windows 11 VM on Virtualbox with the name "w11" and a user "admin" with a password stored in vm_password.txt file.

Password Setup: Create a file named vm_password.txt in the project directory with your VM password on a single line. This file is excluded from version control for security (see .gitignore).

VM Configuration: Install VirtualBox Guest Additions in the VM. Shared folder and UI prefs are applied by a separate step after base install (see Setup).

If you are worried about permanently mounting the root of the host Linux system in Windows in read/write mode because of security reasons, you can pause root folder mounting later (see umountRoot section for details).

Additional tips for tuning VM-interacting experience (for true "seamlessness"):

1. Add the attached "disable_taskbar.cmd" to the startup-folder. Press Win+R and then type: shell:startup
2. Configure the VM to automatically shut down when you click the close button in the virtual machine window decorator instead of asking what you want to do.
   • Run from Linux host terminal: VBoxManage setextradata 'w11' GUI/DefaultCloseAction Shutdown.
   • In Windows 11 VM go to Control Panel -> Power Options -> System settings -> When I press the power button -> Choose "Shut down".
   • Reboot (for applying VBox setting).

Setup (simple):

1. Clone and enter the project

git clone https://github.com/ne0YT/Linux-Subsystem-for-Windows_Seamless_windows_apps_on_Linux
cd Linux-Subsystem-for-Windows_Seamless_windows_apps_on_Linux/

2. Create the password file (your Windows admin user password)

echo "YOUR_WINDOWS_ADMIN_PASSWORD" > vm_password.txt

3. Base install (safe; no VM changes)

sudo ./install_LSW.sh

This installs required packages, desktop launchers, and windows.sh.

4. Configure VirtualBox integration (shared folder Z:, seamless UI, taskbar script)

sudo ./configure_virtualbox.sh

Notes:

• VM must be named w11 and have a user admin with the password from vm_password.txt.
• Requires Guest Additions and the guest control service running in Windows.

What the scripts do:

• install_LSW.sh: installs files/launchers only; no VM config.
• configure_virtualbox.sh: sets permanent ROOT shared folder (Z:), GUI prefs (Seamless, mini toolbar, default close action), copies disable_taskbar.cmd to Startup and tries to run it once.

VM Auto-Start: The system automatically starts the VM when you open a file, whether it's powered off or in a saved state. Additionally, whenever the VM is already running, windows.sh ensures a transient ROOT shared folder exists so drive Z: is available even after reboots.

Testing: Always use ./windows.sh README.md to test the system. The script runs in ~0.3 seconds and exits immediately.

Seamless Mode: The installation script configures seamless mode settings. To enable seamless mode:

• Start the VM
• Go to View -> Seamless Mode in VirtualBox
• Or press Host+L to toggle seamless mode

SaveWindows -App:

If you set this up as I did, there's not too much overhead and the VM only restores/starts as soon as you open the first "run with Windows-File". In addition to this, in order to improve performance further, the program SaveWindows saves the state of the w11-VM, and restarts it when needed, so you can temporarily use your full performance on Linux.

umountRoot:

Since giving Windows read/write access to the root of the host Linux system is not secure, or if you are paranoid about Windows tracking, you can pause mounting the root of the host system. To do this, run umountRoot from your DE menu. It will then be mounted again the next time you run any file using "run with Windows-File".

powershell.exe.lnk:

Launch Powershell (need to be opened "using Windows")

uninstall_LSW.sh:

If you want to remove this great Tool.. just run uninstall_LSW.sh

Powershell Launchers

After installation, you will have two new launchers available from your applications menu:

• Powershell in Windows: Opens a standard Powershell session inside your Windows VM.
• Powershell as Admin in Windows: Opens a Powershell session as Administrator inside your Windows VM (with UAC prompt).

You can find and launch these from your desktop environment's application menu, or search for them by name.
