Recover Windows 8.1 Product Key from BIOS?

Windows Vista

Asked by: Adriano Matos

I have an ASUS ROG GL551JW model laptop that came preinstalled with Windows 8.1. I did a clean install of Windows 10. I wiped everything out on the drive, so even the preinstalled apps on the laptop aren't even here anymore. I am not happy with Windows 10 however. If I were to do a clean install of Windows 8.1 using the Windows Installation Media Creation Tool, will the BIOS still be able to recover the product key despite doing a clean install?

I did a restore once after doing a clean install of Windows 10, but it did not go back to Windows 8.1 (I didn't wipe out the drives with this restore though; I just removed the personal files), so I guess I have to use the Creation Tool, but I don't know if doing another clean install will give me back the key and I do not want to risk anything.

Thank you!

With Windows 8/8.1 The Product Key on preinstalled Operating Systems (HP, Acer, etc) is embedded in the BIOS in the Motherboard, so that the lost and/or worn C.O.A. Sticker problem is no more.

When you reinstall it SHOULD pick up the Product Key and activate the system automatically.

If it does not, follow these steps:
