In 2012 I bought a retail copy of Windows 7 Home edition and installed it into the system I built. Since 2012 I took advantage of a free upgrade to Windows 10. I am now looking at finally upgrading my computer system and building a new system. Is there any legal way to get Windows 10 or 11 installed on my new system using what I bought in 2012? I do not intend to continue using my old system once I build a new one.
