Uninstalling

If you ever need to uninstall OneCommander you MUST uncheck all these options 

(if you have set it as a default file manager, uninstalling it will leave you without a default file manager)

Close OneCommander completely

MSI Installer or Microsoft Store version:

Uninstall the same way as any other Windows application, either from Programs an Features, the Settings app, or right-clicking it in Start menu and selecting Uninstall

Portable version

Portable versions are not installed so there is nothing to uninstall. Once you have ensured that the above settings are not enabled, you can just delete the folder where OneCommander was saved and remove the desktop/start menu shortcut if you have manually created those. OC doesn't use Windows Registry to save any settings
