If you see Event ID 1037, Secure Boot DBX update to revoke Microsoft Windows Production PCA 2011 is applied successfully, you may be wondering what this is. This scenario involves a system that detects an event related to a specific type of certificate known as the Microsoft Windows Production PCA 2011 certificate. This certificate plays a crucial role in booting software, which initiates a computer’s operating system.
Event ID 1037 Error Secure Boot Dbx update to revoke Microsoft Windows Production PCA 2011 is applied successfully
When the system raises a flag on the Microsoft Windows Production PCA 2011 certificate, it clearly indicates that something is amiss or a security protocol has been triggered. It could be due to various reasons, including the certificate being expired, revoked, or tampered with without authorization. It could also be flagged if the certificate is from an untrusted source or fails to meet specific security standards.
This event’s notification alerts users or administrators that there might be an issue with the booting process related to this certificate. It prompts them to investigate further to ensure the system’s security and integrity. A compromised booting certificate could lead to security breaches or malfunctions during system startup.
Meaning of Event ID 1037
The digital certificate used to confirm the identity of software that loads the operating system (bootloaders) is called the Microsoft Windows Production certificate with a specific plate number. Whenever Microsoft discovers a potential security threat with bootloaders signed by this certificate, it updates the DBX.
This process is a precautionary measure to reduce the risk. Once the DBX is updated, the system logs Event ID 1037 automatically, confirming the update’s successful completion. As a result, boot applications signed with the certificate will not be allowed to participate in the booting process.
I hope this helps!

What is DBX in BIOS?
The signature database (db) holds trusted keys, signatures, and hashes, while the forbidden signature database (dbx) lists untrusted ones. Changes to these lists need a Key Exchange Key (KEK) signature.
What is UEFI Secure Boot?
UEFI Secure Boot is a feature of the UEFI specification that ensures the system boots using only software that has been deemed trustworthy by the hardware manufacturer. This is achieved through a verification mechanism where the firmware checks the boot loader for authenticity before running it.
