For anyone interested! (chocolatey package)

[Journeyover]

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.

Great  Thanks a bunch! will update my uninstall scripts to new silent arguments now.

Edit: New package now has new uninstall string, currently I am leaving the User Data untouched at the moment but I am planning on updating a bunch of my packages when I have time (might not happen for a few days or so, as I am moving in 2 days so don't really have a whole lot of time right now to mess around with things) and so I will be adding a option (Argument) in for people to choose between default (--cb-silent-uninstall-type=0) or to remove user data on uninstall as well (--cb-silent-uninstall-type=1) plus updating my install script with arguments on being able to choose install location if they please for my centbrowser package.
