I had changed the name of the primary alias but i need to get back the old name of the primary alias by keeping the new name of the aliase?

Here a i had changed the name of the primary alias as '*** Email address is removed for privacy ***' to '*** Email address is removed for privacy ***'. But the problem is that i had connected my Skype and other Microsoft features in '*** Email address is removed for privacy ***'. So now I'm not able to change the password of the skype and couldn't be able to get into the other Microsoft features or sites etc, where i had registerd with x@hotmailcom. Due to this reason i had created a new mail id with the old alias name '*** Email address is removed for privacy ***', to get solve the previous problems. But it didn't worked out. Now what i need is that, i like to make this *** Email address is removed for privacy *** and y@hotmail as one, so that i like to solve the problems that i had mentioned above. Can any one have solution for it.
