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. Here's a quick rundown of the program.

The Windows Insider Program is an optional service provided by Microsoft to let users experience the next version of Windows before public release. The program is aimed at early adopters and the "enthusiast" crowd, or people who enjoy beta testing new software. 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

In short, the Windows Insider Program is one big beta. It features three levels, or "rings:" Fast, Slow and Release Preview rings. 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. If that build ends up being stable enough, it gets promoted to the Slow ring, and then eventually it hits the Release Preview ring. 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.

There are, of course, pros and cons to this program. Here are a few of them!

Windows Insider Program pros

Test new features first

The biggest pro to the Insider Program is that users get to test upcoming Windows 10 features first. 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. Sometimes, this means Insiders are using new features months before they roll out officially. 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.

Shape the next version of Windows

Of course, one of the great things about the Insider Program is that Microsoft is listening to its participants. Microsoft encourages Insiders to submit feedback about anything and everything, whether it be about bugs, suggestions or your own ideas. Depending on how popular your feedback is, Microsoft may even take your idea and implement it into Windows.

Be a part of the community

Last but not least, the Windows Insider Program is one big community. A community of 10 million people, in fact, according to Microsoft. That's a lot of people who share similar interests and ideas. If you're a fan of Microsoft or Windows, the Insider Program is a great place to meet other people who are also interested in those things. Sometimes there are even Insider meetups, where you can go in person and meet other people.

Windows Insider Program cons

Your PC may become less stable

The Insider Program is a beta program. It's where Microsoft can release unfinished, buggy code to the public for testing and to garner feedback. As such, sometimes, your PC may become less stable depending on the build Microsoft has released. For the most part, this isn't an issue as Microsoft (usually) doesn't release builds with any major bugs.

It can require a lot of bandwidth

Microsoft often releases a new Windows Insider build once a week, which means you'll be downloading a new build very often. Builds can sometimes range from 1GB to 3GB, so if you're on an internet connection with limited bandwidth, that data is going to be eaten up fast. You could drop down to the Insider Slow ring, which gets builds less frequently, but then you'll also be missing out on the bleeding edge of new features.

Lots of telemetry

Joining the Insider Program will also opt your PC into sending more telemetry, or personal device information, to Microsoft for feedback purposes. If you're not a fan of telemetry, then the Insider Program is not for you. There's no way to limit the telemetry sent back to Microsoft when opted into the Insider Program, so even though it's all anonymous, according to Microsoft, it's still getting sent back and analyzed. So keep that in mind.
