Every time I click on something like msn or itunes, I am asked to "Choose the program you want to use to open this file." I do not get it. So what can I do so I can open these things again, because they will not open.
are you absolutely positive you're trying to open the .exe files? 100% sure they are not empty files?
I figured it out. There was something wrong with the registry. I got a regedit cleaner online and it scanned the registry for problems and fixed them. sweet! I can open my msn, itunes and wmp, etc. again!
