In the hope of turning the wheels and making its webmail more attractive, Microsoft has reinvigorated the Hotmail user interface to provide what is suppose to be a more “user friendly” and enriched webmail experience. While most Hotmail users might not have shifted to the new UI, it is probably because many are still unaware of the change. You can now access Hotmail from the new Outlook.com URL, as well as the mail.live.com and Hotmail.com URLs. The new interface known as Outlook.com uses the Metro interface that has been used in all of the latest Microsoft products including Windows 8, Windows Server 2012 and Microsoft Office 2013. If you are willing to switch to the new Outlook.com user interface, then see upgrade instructions given below.
All you have to do is to simply login to your Hotmail account, click Options and select “Upgrade to outlook.com” from the drop down menu that shows up.
You will be shown a prompt that will provide you with details regarding the new user interface and offer you the option to Upgrade to Outlook.com or choose later (Maybe Later). This is just a simple way of confirming if you would like to upgrade to Outlook.com.
This will upgrade your old Windows Live UI to the latest Outlook.com interface. You can use the same hotkeys on Outlook.com as are available for Microsoft Outlook. If you would like to see the list of available hotkeys, then see the keyboard shortcuts for Outlook.com webmail.

While it might seem like an exciting prospect to try out the latest UI, I would personally advice against it.
