I have two Hotmail accounts which to date have been linked so I can sign in once and see both my email accounts and their emails and folders. Each are used for different purposes and their contents are different. I use Windows Live Mail which is still active on my work PC and have never had an issue with it.

The other day I logged into my default account and found that all my emails were downloading again instead just the new ones.  Then I discovered that the two email accounts have completely synched so each had exactly the same contents and folders as the other one.  Now, every time I receive mail I receive it to both accounts even though I have not setup any forwarding aliases from this PC or any other place like my laptop. However, if I delete or open an email in account, the same does not happen in the other so I've got to deal with both emails in both places -- it's getting to be a drag.

How do I get my previous unsyched version of my accounts back?
