Microsoft confirms the new Secure Boot folder in Windows 11 isn’t a bug, you don’t need to delete it

AI-summarised brief · reviewed before publication

Microsoft has confirmed that the new "SecureBoot" folder in Windows 11 is not a bug, but rather a necessary component for Secure Boot certificates update. The folder is being created ahead of the June 2026 deadline, when Secure Boot certificates issued in 2011 or earlier will automatically expire. The folder contains seven PowerShell scripts intended for IT professionals, but is being rolled out to all users, including those with Windows 11 Home. Microsoft advises users not to delete the folder, as it may be required for future updates. The Secure Boot certificates update is necessary for Secure Boot to work effectively, and most users will receive the update automatically via Windows Update.

💡 Why It Matters

  • · The widespread rollout of Secure Boot 2023 certificates is crucial for maintaining device security, as it blocks unauthorized software from loading during startup.
  • · Microsoft's decision to quietly add the SecureBoot folder to all eligible devices ensures a smooth installation of the certificates, even for users who don't actively manage updates.
