Sure. It's basically MS trying to get people to use their systems.
1. Sign into MS Rewards with your MS account on MS Edge
https://rewards.microsoft.com/
2. Install the MS Rewards Extension
3. Click the Extension and complete all the rewards, polls, quizzes etc.
You get 90 points for using Bing searches. Personally I just search for 'Actors' until I get 90.
You get 12 points for using Edge. I only use Edge for doing Rewards personally.
You get 60 points for searching on a mobile. Again I just search for Actors or something. You can right click on your browser and choose 'Inspect' to fool it into thinking its on a mobile
There are weekly and monthly rewards on the Xbox itself which are usually very easy to do too.
