How to uninstall MasterGo on Windows

This record covers MasterGo 1.11.7, installed through the official installer with machine scope. Back up the folders below when retaining local data.

Close the app

Close the window and tray entry, then use Task Manager (Ctrl+Shift+Esc) to check MasterGo.exe. Quit only processes whose executable paths belong to this app.

Data and settings

Remove with the vendor uninstaller

Find the app in Settings › Apps › Installed apps and uninstall it. Save local data first; use the uninstaller rather than deleting its program folder.

Check the result

Get-Process -Name 'MasterGo' -ErrorAction SilentlyContinue
Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\com.master.electron" -ErrorAction SilentlyContinue | Select-Object DisplayName,DisplayVersion
Test-Path "$env:APPDATA\master-desktop-local-ai-canvas-data"
Test-Path "$env:APPDATA\master-desktop"

No process output means no matching process was observed. A completed installation query with no match means the measured registration is absent; a query error does not prove removal. Test-Path returns True when the path remains and False when absent. True is expected when retaining data.

What Mole lists

The program folder, shortcuts, master-desktop-updater after removal and app-owned mastergo protocol registration are selected; the registration is backed up before removal. %APPDATA%\master-desktop is unchecked. master-desktop-local-ai-canvas-data is personal data, unchecked and excluded from bulk selection; workspaces and session folders survived the retest. Firewall rules are reported only; machine-wide.mg and.mxgp registrations are retained.
