Windows 10: Downgrading to Win 8.1

I wish to downgrade from Win 10 to Win 8.1. I had purchased the laptop with pre-installed Win 8.1 and had upgraded to win 10 later on. I don't have the key to enter when I install Win 8.1.


How can I get my key from my Microsoft account?

Downgrading from a pirated Windows OS

You've already mangled your existing operating system by upgrading to a pirated version of Windows 10. Use your Windows 8.1 disk to do a new installation of your original Windows 8.1 operating system. If you have saved the product key from your original Windows 8.1 operating system, then use that product key again to install Windows 8.1.

You can downgrade from Windows 10 to Windows 8, by following the instructions in the answers to this question: How can I downgrade from Windows 10 to Windows 8?. Why not downgrade the pirated Windows 10 to Windows 8 instead and then change the product key and upgrade legally back to Windows 10? There are two reasons for not doing it this way:

1. Your new Windows 10 can inherit problems from the pirated version of Windows 10.
   
2. It's a two-step process to install Windows 8.1 and upgrade to Windows 10 instead of a four-step cumulative history: Windows 8.1 -> pirated Windows 10 -> downgrade pirated Windows 10 to Windows 8.1 -> upgrade to Windows 10. Even though the two-step method doesn't save any time, it still eliminates two unnecessary steps.
