Note
- Windows Secure Boot certificate expiration
- Important: Secure Boot certificates used by most Windows devices are set to expire starting in June 2026. Microsoft has been updating these certificates on consumer and non-managed business devices for the past months. Devices that haven’t received the newer certificates will continue to start and operate normally, and standard Windows updates will continue to install. We will continue to install the newer certificates via Windows updates in the coming months.
- You can check your PC status on the Windows Security app. If you are an IT administrator, follow the guidance on the Secure Boot Playbook for Windows clients and Windows Server.
Note
- Support for Windows Server 2022 will end in October 2031
- After October 14, 2031, Microsoft will no longer provide free software updates from Windows Update, technical assistance, or security fixes for Windows Server 2022. We recommend that you upgrade to a later version of Windows Server.
