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!

Win7 key to reinstall Win10

My PC used to run Win7 when I bought it few years ago, upgraded it to Win10 later as it was free.

I would like to reinstall my windows 10 now but do I use my old Win7 product key to reinstall Win10? or is the key no longer usable at all?
