Finding Original Win 8 Pro Key after Media Center Upgrade

[windows10]

Here's the problem:

I purchased two Windows 8 Pro Keys from Microsoft, one for myself and one for a laptop I sold. Unfortunately, after I upgraded to Windows Media Center, I lost track of which key belongs to my laptop. Since a new key was generated for my installation with Media Center, I have no idea how to determine which original key belongs to my laptop. Any ideas on how to determine the original key would be greatly appreciated. Thanks!

It didn't yield any keys. Is there a possibility that I ran the vbs script incorrectly?

Thank you, David Bailey. Unfortunately, ShowKey v1.2.vbs & ShowKey v1.3.vbs were able to pull up the current key, but not my original Windows 8 Pro key.

If you upgrade like this core-->pro-->prowmc then your pro key is gone.
However if you innstalled pro then upgraded to prowmc use Windows 9 Product Key Viewer click IE KEY option.
