To check your BIOS version from the Command Prompt, hit Start, type “cmd” in the search box, and then click the “Command Prompt” result—no need to run it as an administrator.
You copy the BIOS file to a USB drive, reboot your computer, and then enter the BIOS or UEFI screen.

On Windows 7, 8, or 10, hit Windows R, type “msinfo32” into the Run box, and then hit Enter.
The BIOS version number is displayed on the System Summary pane. Different motherboards use different utilities and procedures, so there’s no one-size-fits-all set of instructions here.
