So I have a Lenovo Y510P IdeaPad, I upgraded it to Windows 10 last December and wanted to downgrade it back to Windows 8/8.1 due to some issues that many said are due to the fact that the model doesn't really support Windows 10 thus I experience the problems. However, since it has been more than a month from the upgrade, I can't just roll it back to previous OS and am wondering if there is any way I can find out what my original product key for the pre-activated Windows 8 so I can perform a clean reinstall with it.

If windows came pre-installed on your laptop, the key might be on its certificate of authenticity.
Alternatively, you can obtain the key using third party softwares like ProduKey. It'll display the currently activated key on your system.
