Windows 11 works well with Aorus Z390 Pro hardware.
You're setting up your PC for Windows 11 on an AORUS Z390 Pro with a mobile chip. You've turned off CSM and turned on TPM, and you're wondering if Secure Boot should be activated. It's good to know whether it adds any advantages.
To grasp Secure Boot, start by understanding how a machine operates. The processor grants exclusive rights to the initial program loaded, granting it unrestricted access. This concept aims to let an operating system manage itself, hence the name. When you power on, the BIOS handles setup and verification, then launches the first application: the operating system. The CPU fetches the OS, which holds special "administrative" rights, enabling its functions. This process is efficient, but if malware alters the bootloader settings to replace the legitimate OS with a hidden version, it can masquerade as the operating system. It bypasses normal commands, allowing itself to run undetected and intercept all actions. Even security tools like antivirus scans may fail because the malware manipulates memory to stay invisible. Monitoring via Task Manager or network analyzers often shows discrepancies, yet the system continues unnoticed. Rootkits can exploit this by hiding their presence entirely. A clean installation resolves the issue, restoring proper verification. SecureBoot adds a layer of protection by confirming the OS is authentic, preventing such covert takeovers. Though rare, these threats arise from complex development. The feature enhances security without affecting performance, only activating during OS startup and completing in milliseconds. It’s advisable to enable it, as disabling it can leave legacy systems vulnerable or prevent booting entirely if unsupported.
