I'm planning a new pc for my dad (parts for reference: https://pcpartpicker.com/list/Td3bcT). He ran Windows 7, and I heard that the upgrade tool to get Windows 10 for free still works.
However, I'm wondering if I can use his Windows 7 key on his old computer to activate Windows 10 on the new computer. If so, what do I need to do?
If that cannot work, can I use a Windows 10 key on an old crappy laptop of mine and transfer it to the new computer? If so, what do I need to do?
