Actions Required for the Expiration Date of August 11, 2026

Question

I upgraded from Windows 10 to Windows 11 following instructions found on YouTube, but I have received a notification stating that the security certificate (flight certificate) for the Insider Preview build currently installed on my device will expire on August 11, 2026, and that I must migrate to a build signed with a new certificate before that date. However, I am unsure of the specific steps I need to take. What measures or actions should I take to continue using this PC? Could you please provide specific instructions?

Hi Onetz S,

The notification you are seeing is related to the expiration of the signing certificate used for Windows Insider Preview builds on August 11, 2026. This is part of a planned maintenance process for Insider builds and typically requires installing a newer Insider build that includes the renewed certificate. Link references: Windows Insider Preview certificate renewal (Expiration: Aug 11, 2026)

To help ensure your device remains up to date:

1. Press Windows + R, type winver and note your current build number.
2. Open Settings > Windows Update and select Check for updates.
3. Install any available Windows Insider Preview updates and restart your device.
4. Repeat the update check until no further Insider builds are offered.

If no update is currently available, continue checking Windows Update periodically, as renewal builds are being released in stages across Insider channels.

I hope this clarifies the message. If you're unsure whether your device has received the required update, please share your winver information and Insider channel, and the community can help verify your build status.
