Where can I find my BIOS version in Windows?

When Windows starts, the OS loads information about the main computer BIOS and video BIOS and stores the following information under the HKEY_LOCAL_MACHINEHARDWAREDESCRIPTIONSystem registry subkey:

SystemBiosDate
SystemBiosVersion
VideoBiosDate
VideoBiosVersion

This information appears in the registry for informational purposes only; changing these items’ values has no effect on the system.
