Once on the homescreen, users will notice the tiles, which both include updated information as well as linking through to applications.
There are a range of different "hubs" as well, which can be accessed via the touch of a tile. These organise the user's information into five different hubs: People, Pictures, Office, Music and Video, as well as Games.
Woodman said with the Office section, Microsoft "truly believes this is going to be the best phone for productivity."
Included in Office are Documents, OneNote and SharePoint, meaning mobile workers can gain remote access to the files they need.
Outlook, meanwhile, has been designed to be "quick and easy", making it simple to filter messages into categories.
As for Bing, the mobile search function provides more than just links, also including relevant information such as immediate flight times if the user is looking for a specific flight.
"It is about making that information super relevant," Woodman said.
