Microsoft Rewards is a free program that’s included in your Microsoft account. To join, you simply need to sign up and check that you’re still signed in to enjoy the rewards. Participants can earn points when they search on Bing.com and make purchases in Windows 10 or via the Microsoft Store online. Points can be used for things like sweepstakes, gift cards, or donations to a charity. However, searching on Bing.com or buying things from the Microsoft Store doesn’t earn points in all countries.
