Windows 10: Win7 to Win10 using Win7 product key

I have an old computer that was running Windows 7 with an original product key, I just purchased a used laptop that is much faster than my old box had Windows 10 installed on it and would like to use my Windows 7 product key to activate Win10. I tried entering the Win7 product key but it tells me it's invalid. How can I successfully do this?

Win7 to Win10 - Product key question

I'm just wondering if the product key I purchased years ago for Win7 will still be valid if I reserve Win10 and install it?

Say for example I want to have Win7 on my main studio PC (as I know all my DAWs and VST plugins work on there perfectly), but also run Win10 on my other machine, would that be possible from the same key? Or would I void the Win7 key as soon as I reserve
and install Win10?

I rely on Win7 for work, so the last thing I want is to void my key for it.

I often reformat my system and I'd hate to do so then find out my Win7 key no longer works...

Thanks in advance!
