Pre-installed office product key

[3lfa]

Not sure if this is the right board for this question but when I bought my desktop back in 2014 I had Office Home and Student pre-installed on it. This was a while ago so I don't remember if I had to manually activate Office and type in a product key or not. Either way I'm trying to figure out where my product key is. Would I have received it with my computer? Or did HP use a key when they installed it? Is there any way I can find it? I'd like to use the key to set up office on a new laptop.

Thank you!

Since it came preinstalled, there was probably a card that came with it bearing the Office product key.

But, if you look around for a utility called Magical Jellybean Key Finder and run that, it should show the Office product key.

Good Luck
