@Josee,
You have made at least two mistakes :
1. doing changes in the original installation of MSN without having the possibility of going back to a previous state, that works properly.
2. getting angry with yourself due to your own actions and blaming M$ for it. An angry person can't think straight anymore. I never get angry with software, except my wife. Every software sucks, some suck even more than others. Keep that in mind.
I don't like M$ either, but I don't hate M$, I have pity with M$. M$ became a bank and does nothing but buying and selling software without any creativity. That's why smaller software companies create better software than M$ because they didn't lose their creativity like M$.
You seem to assume you can do anything with software. No wonder you are in trouble. There are certain rules, in case you didn't know.
Next time when you fool around with software, do an Image Backup of your system BEFORE fooling around OR
use "Immediate System Recovery" like me, which is much faster and then you can do anything with any kind of software or Windows and without getting punished for it. Be smart, not angry.
Also separate system and data, in stead of storing system and data together on one large partition-C, which is also an old-fashioned and out-of-date method of installing computers. Don't become one of these "Users of a lesser God", get back on the horse and become a man with a plan. I know, I'm just a "Starter", don't take me seriously.
End of Speech (EOS). Pffft
