Windows Messenger

Hey everyone. I just got a new hd, and I had to format. I forgot how to remove and disable messenger. I then remembered to unhide all folders, then go to c:windows\inf then open sysoc.inf and change it from "msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,HIDE,7" to "msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,,7", which allows you to see messenger in add/remove components. However it will not let me uncheck the box, any suggestions?

Here is a link

I've seen that page before, and it doesn't help. Like you should be able to uncheck the box in add/remove components after you unhide it, but it won't let me for some reason.
