If I may add, concerning junk mail, both WLM and HotMail have the option to "Delete and Block" senders, of course you could always "Unsubscribe" which is usually located at the bottom of the email.
I personally, use WLM as I don't have to sign in to view my mail, which is very convenient, unlike Hotmail and Windows Mail.
Whenever you delete mail from WLM, it should sync with Hotmail and be removed from there as well, may take a day or 2.
You may want to add your Hotmail account to your WLM account;
Open WLM, click on the "Accounts" tab, then click on the "Email+" icon
Link Removed
Hope this helps
