I would prefer to avoid my Messenger being uninstalled or changed to Skype as I already have Skype installed.

I realize keeping a fully functional Messenger is not an option, but I would like to keep the program the way it is, even if it does not continue to work.

Does turning off Windows automatic updates prevent my Messenger from being automatically uninstalled when the time comes?

If not, how can I keep the program / prevent a forced update or switch?
