- Status: Released

Microsoft has officially begun rolling out the revamped Windows Insider Program experience to standard retail versions of Windows 11. If you are running a non-Insider build, you may start seeing updated channel options in your settings menu this week. This change aims to make joining or leaving the testing program easier without requiring a full system reinstall.
Alongside the UI updates for retail users, Microsoft released new Insider Preview builds across multiple channels on June 26, 2026. The Beta channel received Build 26220.8754, while Experimental users got Build 26300.8758. These updates bring stability fixes and new customization features.
New Insider options for retail Windows 11
The biggest news for everyday users is the gradual rollout of the new Windows Insider Program interface to retail builds. Previously, opting into beta or dev channels often meant committing to a specific build path that was hard to reverse without wiping your PC.
With these changes, Microsoft aims to simplify the process. You can now find the updated controls under Settings > Windows Update > Windows Insider Program. The company notes this is a staggered rollout, so not every retail user will see the new options immediately. It will take several weeks for the update to reach all eligible devices.
This shift lowers the barrier for users who want to test new features but fear being stuck with an unstable build. Microsoft emphasizes that switching channels or exiting the program is now much smoother, preserving your data and settings in most cases.
Taskbar size customization arrives
For those on the Experimental channel, a long-requested feature has landed: a dedicated setting for taskbar size. Microsoft introduced this control to make personalizing the taskbar easier and more intuitive.
Instead of digging through registry edits or third-party tools, you can now adjust the taskbar dimensions directly from the settings menu. This update is part of broader improvements to the taskbar experience that Microsoft has been refining over recent months.
This feature is currently exclusive to the Experimental channel (Build 26300.8758). Users on Beta or retail builds will need to wait for further validation before this option becomes widely available.
New build numbers across all channels
Microsoft released updates for every active Insider channel today. Here is the breakdown of the new builds:
- Beta Channel: Build 26220.8754
- Experimental Channel: Build 26300.8758
- Beta (26H1): Build 28020.2366
- Experimental (26H1): Build 28120.2374
- Experimental (Future Platforms): Build 29617.1000 (Canary 29600 series)
Note that the new Windows Insider Program UI changes have not yet reached the Experimental (Future Platforms) channel, specifically the Canary 29600 builds. Microsoft plans to provide an update on this front in the near future.
For IT professionals and power users, these build numbers are critical for tracking specific fixes and feature introductions. The 26H1 builds represent the next major version of Windows, while the Future Platforms channel offers a glimpse into the earliest stages of development.
What this means for you: If you have been hesitant to join the Windows Insider Program due to fear of being locked into a buggy build, now is a good time to reconsider. The new retail UI makes it safer to test features and revert if needed. Meanwhile, Experimental users can finally adjust their taskbar size without workarounds.
