PC Master โ€” Windows Control from WSL2

All Windows binaries are accessible via /mnt/c/Windows/System32/. Call them directly from bash.

Prerequisites

WSL2 interop must be working. If .exe calls fail with UtilAcceptVsock errors, ask the user to run wsl --shutdown in Windows and relaunch WSL.

Processes

# List all processes /mnt/c/Windows/System32/tasklist.exe # Filter by name /mnt/c/Windows/System32/tasklist.exe /FI "IMAGENAME eq chrome.exe" # Kill by name /mnt/c/Windows/System32/taskkill.exe /F /IM chrome.exe # Kill by PID /mnt/c/Windows/System32/taskkill.exe /F /PID 1234

Launch Applications

# Open a URL in default browser /mnt/c/Windows/System32/cmd.exe /c "start https://google.com" # Open an app by name /mnt/c/Windows/System32/cmd.exe /c "start chrome" /mnt/c/Windows/System32/cmd.exe /c "start spotify" /mnt/c/Windows/System32/cmd.exe /c "start notepad" # Open a file with its default app /mnt/c/Windows/System32/cmd.exe /c "start C:\\Users\\User\\file.pdf" # Launch full path /mnt/c/Windows/System32/cmd.exe /c "start \"\" \"C:\\Program Files\\App\\app.exe\"" โš ๏ธ cmd.exe /c start must be run from a Windows path. Use /mnt/c/Windows/System32/cmd.exe /c "cd /d C:\ && start ..." if cwd is a UNC path (WSL path).

PowerShell (advanced)

PS=/mnt/c/Windows/System32/WindowsPowerShell/v1.0/powershell.exe # Run a command $PS -NonInteractive -Command "Get-Process | Select-Object -First 10" # Get window titles $PS -NonInteractive -Command "Get-Process | Where-Object {$_.MainWindowTitle} | Select-Object Name, MainWindowTitle" # Set volume $PS -NonInteractive -Command "(New-Object -ComObject WScript.Shell).SendKeys([char]174)"

Screenshot

# Take a screenshot and save to Windows desktop PS=/mnt/c/Windows/System32/WindowsPowerShell/v1.0/powershell.exe $PS -NonInteractive -Command "Add-Type -AssemblyName System.Windows.Forms; [System.Windows.Forms.Screen]::PrimaryScreen | ForEach-Object { \$bmp = New-Object System.Drawing.Bitmap(\$_.Bounds.Width, \$_.Bounds.Height); \$g = [System.Drawing.Graphics]::FromImage(\$bmp); \$g.CopyFromScreen(\$_.Bounds.Location, [System.Drawing.Point]::Empty, \$_.Bounds.Size); \$bmp.Save('C:\\screenshot.png') }"

File System (Windows paths)

# Windows C:\ is at /mnt/c/ in WSL ls /mnt/c/Users/ cat /mnt/c/Users/Username/Desktop/file.txt cp /mnt/c/Users/Username/Downloads/file.zip /mnt/c/Users/Username/Desktop/ # Find Windows username ls /mnt/c/Users/ | grep -v "Public\|Default\|All Users"

System Info

# Windows version /mnt/c/Windows/System32/cmd.exe /c "ver" # Disk usage /mnt/c/Windows/System32/cmd.exe /c "wmic logicaldisk get size,freespace,caption" # Network info /mnt/c/Windows/System32/ipconfig.exe

Common Patterns

Close and reopen an app: /mnt/c/Windows/System32/taskkill.exe /F /IM chrome.exe sleep 2 /mnt/c/Windows/System32/cmd.exe /c "start chrome" Check if app is running: /mnt/c/Windows/System32/tasklist.exe /FI "IMAGENAME eq spotify.exe" | grep -i spotify && echo "Running" || echo "Not running" Open a specific website: /mnt/c/Windows/System32/cmd.exe /c "start https://www.google.com"

Notes

Output may contain garbled characters (Windows encoding vs UTF-8) โ€” this is normal, content is still readable Some GUI apps launched via start won't produce output โ€” that's expected For interactive PowerShell scripts, write to a temp file and read it back instead of capturing stdout directly See references/windows-apps.md for common app executable names

Category context

Code helpers, APIs, CLIs, browser automation, testing, and developer operations.
