Last Updated: November 11, 2025

If you’re eager to explore the latest features and improvements in Windows 11, enrolling in the Windows Insider Program is a great way to gain early access to preview builds. This guide will walk you through the necessary steps to install these builds on both Windows 11 and Windows 10 devices, as well as discuss the various channels available for testing.

Available Channels in the Windows Insider Program

Windows 11 provides four channels within the Insider Program, each catering to different types of users:

Dev Channel: Targeted at technical users, this channel is more stable than the Canary but still prone to errors and bugs.
Beta Channel: Suitable for those who want to preview potential future features, this channel typically contains more stable builds aimed at broader testing.
Release Preview Channel: The most stable option, this provides final versions of upcoming releases before they’re rolled out widely, featuring advanced quality updates.
