when checking on line forms or MS website, it says that it will automatically upgrade to Outlook.com from Hotmail Plus, as far as i can see it all looks the same to me when i go into my mail account?

how can i tell if its upgraded?

i have signed into Outllok.com site with my hotmail account and password and then i see it has the Outlook.com view on screen but when i then go back into the hotmail plus screen, it look like the old hotmail plus???

any ideas??
