Hi Ravi,
Thank you for posting your question in the Microsoft Q&A Forum.
The "2100" star bonus in Microsoft Rewards is a special bonus you can earn by using Bing for genuine searches. It represents the maximum number of bonus points (2100 points) you can get as part of the Bing Star Bonus system.
You can earn bonus points by:
- performing Bing searches that comply with the program's guidelines.
- The points accumulate over time, with smaller increments visible as partial progress.
- When you reach 2100 points, you hit the maximum star bonus for a period.
Examples would include making actual web searches in Bing daily, gradually accumulating the Bing Star Bonus points until you reach the full 2100 points.
