Microsoft's Windows Secure Boot Overhaul Reshapes Security Landscape. After 15 years of relying on the same security certificates, Microsoft has announced a significant shift in its Windows security infrastructure. The company is set to expire critical Secure Boot certificates in just two weeks, marking what industry experts are calling a watershed moment for the operating system's boot security protocols. Secure Boot is a fundamental security feature that prevents unauthorized software from loading during the Windows startup process. By expiring these certificates, Microsoft is forcing a comprehensive update across its ecosystem. This change affects millions of devices worldwide and represents one of the most significant security infrastructure updates since Secure Boot was introduced in Windows 8.
