Windows Insiders are being urged to update their PCs to the latest build within the coming week. This update is crucial as it includes a renewed flight certificate, which is set to expire on August 11, 2026. Flight certificates play an essential role in encouraging users to keep their devices updated and operating on supported versions of Windows. Microsoft routinely issues these renewed certificates to maintain system integrity.
Importance of the Renewed Flight Certificate
Microsoft has highlighted the significance of this renewed flight certificate, noting a shift from previous practices where renewals primarily impacted users in the Canary Channel. Now, this update applies universally across all Insider channels, including Experimental and Beta. A brief reminder regarding the flight certificate is prominently featured at the top of the change log for the latest Insider build:
“Today’s Experimental (Future Platforms) build contains a renewed Windows Insider flight certificate. Windows Insider Preview builds use flight certificates that are renewed periodically to help ensure Insider devices remain on supported builds and continue receiving future Insider Preview updates. The current flight certificate expires on August 11, 2026, so please update your device to a build containing the renewed flight certificate before that date.”
For those seeking more detailed information, Microsoft has provided additional documentation. However, the primary takeaway remains clear: Insiders should promptly update their PCs to a recent build. To assist users in this endeavor, Microsoft has shared a helpful chart outlining the necessary updates across various channels.
| Channel | Core | Minimum Build | Experimental | Future Platforms | 29634.1000 (available July 27, 2026) | Experimental | 26H2 | 26300.9032 (available July 31, 2026) | Experimental | 26H1 | 28120.2630 (available July 31, 2026) | Beta | 25H2 | 26220.9022 (available July 31, 2026) | Beta | 26H1 | 28020.2623 (available July 31, 2026) |

After completing this one-time larger update, users can expect their PCs to revert to receiving regular updates seamlessly. Failure to update to a build with a fresh flight certificate will result in a warning message stating, “This build will expire soon,” appearing on the desktop. Additionally, automatic background updates will cease once the flight certificate reaches its expiration.
To ensure continued support and functionality, users are encouraged to navigate to Settings > Windows Update to install the latest build if they have not yet done so. Regular updates are essential for Windows 11 test builds, as they are designed to expire relatively quickly, reinforcing the need for ongoing vigilance among Windows Insiders.
