How to check BIOS version on Windows 11?


BIOS stands for “Basic Input/Output System.” It is a firmware or software component that resides on a computer’s motherboard and is responsible for initializing and managing hardware components during the boot process. BIOS performs essential tasks such as POST (Power-On Self-Test), booting the operating system, and providing an interface for configuring hardware settings.

In modern computers, BIOS has been largely replaced by UEFI (Unified Extensible Firmware Interface), which offers more advanced features and improved security. However, the term “BIOS” is still commonly used to refer to the firmware that performs similar functions in older or legacy systems. BIOS or UEFI plays a critical role in the startup process of a computer, ensuring that hardware components are functioning correctly and facilitating the loading of the operating system.

Why is important to have the latest BIOS version?

Having the latest BIOS version is crucial for several reasons. It often includes vital updates, bug fixes, and security patches that enhance system stability, reliability, and security. Newer BIOS versions provide support for the latest hardware components, ensuring compatibility and optimal performance. They can resolve known issues and improve system efficiency, reducing crashes and errors. Additionally, BIOS updates may introduce new features or customization options. Failing to keep the BIOS up to date can lead to hardware compatibility problems, security vulnerabilities, and decreased system reliability. Regularly updating the BIOS is essential for a smooth and secure computing experience.
