The Windows 7 key should work under Windows 10. Just make sure you have installed the correct version of W10 that the key corresponds to. In other words, if your key is from a Home version, install the Windows 10 Home, don't install Pro or other versions.
Did you get an error message with the key that you tried?

Of course it doesn't work. It's for Windows 7.
Solution: Install Windows 7. There is now a free upgrade from Windows 7 to Windows 10.

You might have to purchase one from Microsoft, or use the product key to install Windows 7 and then upgrade it to Windows 10.
