BIOS Update under Windows

The Basic Input/Output System (BIOS) update is not a common part of Windows maintenance because it is not part of the system. Therefore, if necessary, it should be performed as a separate operation.

Modern motherboards are already running Unified Extended Firmware Interface (UEFI) instead of the outdated, unsafe BIOS, which supports larger hard drives (up to a few TB), mouse cursor usage, and fastr boot time. Both UEFI and BIOS are low-level software that start after you press the power button on your computer, synchronizing the hardware with the software and helping to start Windows.

WARNING: Update the BIOS, or UEFI at your own risk. An update error can cause an unusable system, or even cause hardware damage. Back up your files, images, videos, and documents, if possible, to an external drive before upgrading.

Quick Tip: Restoring the BIOS to an earlier version is not recommended, as it does not support older hardware and does not update the BIOS if your computer or laptop is working properly, even if a newer version is available. Please seek help from an IT professional!

Updating the BIOS is similar to updating the operating system software, but it is a different process because the BIOS software is not stored on the hard disk, but on the chip on the system board. Windows is constantly updated, but the BIOS no. If an update is available, it can be downloaded from the manufacturers' website.
