Microsoft's Windows Insider Program allows users to engage with upcoming Windows features and updates before their official release. Participants can choose from four testing channels:
1. Canary Channel: Most experimental, high risk, currently testing Windows 11 25H2.
2. Dev Channel: Medium risk, currently testing Windows 11 24H2.
3. Beta Channel: Low risk, currently testing Windows 10 22H2 and Windows 11 23H2.
4. Release Preview Channel: Very low risk, currently testing Windows 10 22H2 and Windows 11 24H2.
Switching to a lower channel requires a complete reinstallation of Windows. The program includes the Feedback Hub app for submitting issues and suggestions. Participants may face stability issues, especially in higher-risk channels, and their devices will send more telemetry data to Microsoft. Frequent updates are released, often on a weekly basis.
