Microsoft recently rebranded its cloud storage service to OneDrive and to encourage customers to use the service (and Bing), the company is offering 100GB of OneDrive storage for one year to all those who sign up for the Bing Rewards program and earn 100 points.
According to Microsoft is this a $50 dollar value and anyone who sign up for the rewards program and simply use Bing, set search engine as the homepage, and various other related Bing tasks on Windows, Windows Phone, Xbox, Skype, or on any platform you can use the search engine can earn points. When you reach 100 points you can redeem them for 100GB of OneDrive storage. To make it a bit easier the company is giving away 20 points just to get into the program.
For all the terms and conditions, visit the Bing Rewards page.
Update: The Bing Rewards offer to get the free OneDrive storage for one year is only available in the U.S.
