Microsoft Releases 5 Windows 11 Insider Builds Before August 11 Certificate Expiry
3 articles · Updated · Windows Blog · Jul 31
Summary
Five new Windows 11 Insider Preview builds landed across Beta and Experimental channels, and all include renewed flight certificates that users must install before the current certificate expires on August 11, 2026.
Those certificates keep Insider devices on supported builds and eligible for future preview updates, making the refresh the key requirement behind this week's releases.
Builds 26220.9022 and 26300.9032 headline the drop, alongside Beta 28020.2623, Experimental 28120.2630, and Future Platforms 29639.1000.
Taskbar changes now reaching Beta add top, left and right placement options plus a smaller taskbar mode, though some features—such as touch gestures, Search box support and Ask Copilot in alternate positions—are still in progress.
Experimental builds also tweak adaptive hibernate behavior, reducing hibernation above 80% battery and triggering it sooner below 10% to balance instant-on resumes with battery preservation.
