That's a lot of people who share similar interests and ideas. A community of 10 million people, in fact, according to Microsoft. Last but not least, the Windows Insider Program is one big community. Depending on how popular your feedback is, Microsoft may even take your idea and implement it into Windows. Microsoft encourages Insiders to submit feedback about anything and everything, whether it be about bugs, suggestions or your own ideas. Of course, one of the great things about the Insider Program is that Microsoft is listening to its participants.
This is beneficial if you're an IT professional or developer testing out the upcoming features to make sure they don't affect anything important. Sometimes, this means Insiders are using new features months before they roll out officially. Sure, some of the features may not be finished, but for the most part, the features that do show up for Insiders in builds are more or less done.
The biggest pro to the Insider Program is that users get to test upcoming Windows 10 features first. Now, the Insider Program is still a beta program, which means those participating in it should know that sometimes a build that gets released can be troublesome. If that build ends up being stable enough, it gets promoted to the Slow ring, and then eventually it hits the Release Preview ring. Microsoft releases unfinished builds of Windows 10 to Insiders in the Fast ring, and they submit feedback to Microsoft about what they like, dislike, and any issues they may be experiencing. It features three levels, or "rings:" Fast, Slow and Release Preview rings. In short, the Windows Insider Program is one big beta. Besides just using the software, Microsoft encourages testers to send feedback on their experiences through a specialized app, which includes ratings and a place to leave notes to the Windows development team The program is aimed at early adopters and the "enthusiast" crowd, or people who enjoy beta testing new software. The Windows Insider Program is an optional service provided by Microsoft to let users experience the next version of Windows before public release. Microsoft's Windows Insider Program is home to 10 million Windows fans, enthusiasts, and professionals who are all interested in what's next for Windows 10.
