Secure boot is a security feature built into Windows 8/8.1 & 10 and later versions. As we know, Microsoft uses UEFI-based computers nowadays. Microsoft secure boot technology was introduced with Windows 8.1, along with the UEFI BIOS specification. In Windows 10, the secure boot was enabled by default, even if it wasn't on supported hardware.
Secure boot prevents third-party operating systems, including Linux, from being installed without Microsoft's permission. By default, Windows 10 boots only signed drivers. If you want to use non-signed drivers, you must disable secure boot.
Secure boot prevents some software - including the old version of Microsoft Office and many third-party programs - from loading while the system boots. If not disabled, any malware running on the system could disable secure boot. Secure boot refers to the security features built into Windows 8 and later versions. It was introduced to protect users from malicious attacks and prevent unauthorized access to sensitive data on the system.
When we use our computers (Windows), they run programs stored inside an encrypted file called boot. When the computer starts up, it first loads program files from this boot file instead of operating directly from random locations on the disk. Microsoft included a feature called secure boot to ensure that only trusted software can load and execute on the machine. By default, secure boot is enabled in newer Windows OSes and requires a special setting to disable it. Insecure devices may allow malware to take over the device without the user's knowledge.
Secure boot prevents attacks by requiring that the CPU be configured appropriately before loading the operating system. If the configuration settings do not match what is on the hardware, then the CPU wont load anything until the correct settings are applied.
Conclusion: When you turn on your PC, Windows starts loading automatically. This process involves booting into the operating system. During this time, Microsoft uses the secure boot feature to verify that your hardware meets certain security standards before allowing Windows to load.
Secure boot is a new technology introduced by Microsoft in its latest version of Windows 8 and later versions. It requires manufacturers to authenticate their devices using a unique key during startup. In other words, it ensures that only legitimate softwares and drivers load up.
