bios update lenovo g580 20157

hello, recently i had to clean install windows 10 32 bit on my laptop (g580-20157) and while installation i found that the bios version is 62CN31WW. i realised that i have never updated the bios to next version. there are two updates which i missed,  62CN44WW for windows 7 and 62CN97WW for windows 8. the problem is, the support page on lenovo asks to downgrade to windows 7 to update bios to 62CN44WW and upgrade to windows 8 to get the 62CN97WW. as it was clean install the windows 7 got deleted from my laptop. is there any solution such that i can avoid downgrading and yet update the bios to latest version?

If your notebook is working fine now, there may not be a need to push the BIOS upgrade regardless.

I only upgrade if the new BIOS has a fix, or feature that I am looking for. The reason is just plain simple - if the BIOS fails (and they do fail) you end up with a very expensive door stop.

BIOS passwords are not set in the upgrade process, they are only applied by the end user of the computer.  IF a BIOS password was applied in the past, then not used or cleared it will only be resolved by replacing the system board at a service center.  There are no "backdoors" or "clear cmos" options to overcome the BIOS lock issue.
