How To Check Your BIOS Version And Update BIOS Windows 10

You may have noticed the acronym BIOS in a lot of places on your Windows computer. Some applications could have asked you to update the BIOS to run. You may have pressed the key that launches the BIOS menu, while booting your PC, by accident.

Wherever we may have seen it, we immediately understood that it was something important. If you did not know about the BIOS menu, you probably do not know that you will have to download BIOS updates and that it can help your PC greatly.

Today, we will be your guide toward the BIOS interface and the BIOS update process on your Windows 10 computer. 

What Is A BIOS?

The Basic Input/Output System (BIOS) is a collection of scripts that are stored on ROM memory storage or a flash drive, which is connected to the motherboard. This BIOS script is what directs your computer to locate the Operating System (OS) and helps it boot the OS up on your computer.

In simpler words, the BIOS facility is the link between the computer hardware and the OS. Without a BIOS, the hardware will not be able to find the installed OS from a huge collection of data, that is required for the system’s functioning.

While we are on the topic of BIOS, it is important to understand the Unified Extensible Firmware Interface (UEFI). The UEFI is the modern replacement for the BIOS and the newer link between the OS and hardware’s firmware. 

Your computer boots up faster with a UEFI, which also has more address space. Statistically, the UEFI is a lot better than the BIOS feature. This doesn’t make the UEFI different from the BIOS. A UEFI is the same as a BIOS, but with new features. 

Do I Need To Download BIOS Updates For My Windows 10 PC?

This is a tricky question. There are a lot of ups and downs to updating the BIOS version on your computer. 

The motherboard or laptop manufacturer releases a new BIOS version only when there are minor bugs to be fixed while booting up the PC. You might also receive features like system security upgrades, new hardware support, booting bug fixes, increase compatibility, and system performance upgrades.

There is one major risk that you have to be willing to take when you update your BIOS versions on your PC. Moving to a newer one from the current BIOS version has to be done very carefully as any mistake like a system crash, freeze, or a power cut.

If this happens, the computer’s boot-up process will crash, and your computer will not be able to boot up again, normally. Besides, there aren’t many added features in every new BIOS update and no visible difference can be noticed from this. 

Also, choosing the correct version of the BIOS file can be quite complicated and you cannot put the wrong BIOS into your computer as it can, obviously, cause problems on your PC. It is important to be very cautious when you are trying to install a BIOS update on your computer. 

The only logical answer to the above question is that the BIOS version needn’t be upgraded until there are problems with your computer and there is a desperate need to update BIOS for your operating system. 

How Do I Check What BIOS Version My Computer Is On?
