Yes, KEK is stored in UEFI firmware/NVRAM, not just Windows; you’re probably okay for now if Secure Boot is enabled and Windows Update/BIOS are current, but the KEK should eventually be updated via Microsoft/OEM firmware updates because Microsoft says both DB and KEK need the newer 2023 certs before the older Secure Boot certs expire in 2026.

Generally, if the KEK is not updated and you haven't encountered issues with Secure Boot or firmware updates, your system is likely still safe.

The original 2011 Microsoft Secure Boot Key Exchange Key (KEK) and Signature Database (DB) certificates are expiring in June and October 2026. To ensure your system continues receiving early-boot security updates, these must be replaced with the updated 2023 certificate versions.
Most supported Windows 10 and Windows 11 devices will receive this update automatically via Windows Update.
Run PowerShell as an administrator and execute the following commands: [1, 2]
Check for the 2023 KEK:
[System.Text.Encoding]::ASCII.GetString((Get-SecureBootUEFI KEK).bytes) -match 'Microsoft Corporation KEK 2K CA 2023'
Check for the 2023 DB Signatures:
[System.Text.Encoding]::ASCII.GetString((Get-SecureBootUEFI db). bytes) -match 'Microsoft UEFI CA 2023
