How to uninstall MPC-BE on Windows
This guide covers the official MPC-BE 1.9.1 x64 Windows installer. Quit the player before uninstalling.
Back up settings and data first
After quitting the app, copy any data folder you want to keep to another location and check the copy. These locations were observed in this test; keep your own projects and files separate.
| Location | Contents | What to do |
|---|---|---|
%ProgramData%\MPC-BE |
Player data | Keep for reuse; remove only to reset |
%APPDATA%\MPC-BE |
Player data | Keep for reuse; remove only to reset |
HKCU\SOFTWARE\MPC-BE |
Player settings | Export this exact key in Registry Editor before resetting it |
Uninstall the app
Uninstall MPC-BE from Windows Settings. The measured program folder was %ProgramFiles%\MPC-BE. The vendor asks whether to delete settings; the measured run kept the default No.
Check the result
Test-Path "$env:ProgramFiles\MPC-BE"
Test-Path "$env:ProgramData\MPC-BE"
Test-Path "$env:APPDATA\MPC-BE"
Test-Path 'HKCU:\SOFTWARE\MPC-BE'
Test-Path "$env:ProgramData\Microsoft\Windows\Start Menu\Programs\MPC-BE x64"
Test-Path (Join-Path ([Environment]::GetFolderPath('Desktop')) 'MPC-BE x64.lnk')
Test-Path returns False when that exact path is absent and True when it still exists. A data path returning True is expected if you kept your settings or data. If a query reports an error, resolve it before deciding whether the path is absent.
What Mole lists
The program folder, desktop and Start menu shortcuts, and usage records are selected by default. %PROGRAMDATA%\MPC-BE, %APPDATA%\MPC-BE and HKCU\SOFTWARE\MPC-BE appear as rows listed but not selected by default. Leave them unchecked to keep your settings.
When selected, the user settings key is exported to %LOCALAPPDATA%\Mole\backups before removal. The machine-wide HKLM\SOFTWARE\MPC-BE key is kept.
What this test covered
Tested on October 6, 2026, in a Windows 11 ARM64 VM with a Mole development build. The measured bulk uninstall selected all three data rows. All six checks returned False, the native app list had no matching entry, and a successful process query found no owned process. Real media, external uninstall and a released Mole package remain untested.
