In my recent post, https://deploymentbunny.com/2026/04/07/secure-boot-2026-essential-updates-and-fixes/, I referenced the CheckSecureBoot script used to validate Secure Boot configuration during deployment. The purpose of the script is to be able to check the satus of the upcoming changes for the Secure Boot Certificate issue that will happen in the summer of 2026.

I just want to give a quick heads‑up that the script has now been updated.

The update improves detection logic and includes some refinements based on recent testing and community feedback. If you’re using this script in your deployment workflows, I strongly recommend grabbing the latest version.

• Script location:
  https://github.com/DeploymentBunny/Files/tree/master/Tools/CheckSecureBoot
• What’s new:
  Full details about the changes are documented here:
  https://github.com/DeploymentBunny/Files/blob/master/Tools/CheckSecureBoot/README.md
• New name:
  Not important, but the new name is Check-SecureBoot.ps1
• New Switch:
  -Silent, no output, instead it stores the data in .log and .json files
• Log Location:
  Now it defaults to %TEMP\SecureBoot-Diagnostics
• Recomendations:
  When running in a normal mode it will tell you in plain english what you need to do

As always, feedback is welcome

Until next time
