This feature has been added in 2.8.5.75.
You can now use "setup.exe --uninstall --cb-silent-uninstall-type=0" to uninstall cent browser silently with User Data untouched, and use
"setup.exe --uninstall --cb-silent-uninstall-type=1" to uninstall cent browser silently and remove User Data.
"--force-uninstall" is no longer needed.
