Hello,
Last night up upgraded from Win7 Ultimate to Windows 10. Windows 10 shows activated, but I never received a Windows 10 "key". I saw another topic it was noted that you would use your current key for the OS you upgraded from. If I were to do a fresh install with an .ISO, I would just use my current Win7 Ultimate key?
Regards
Hello Hobo Horse, and welcome to Ten Forums.
You don't get a product key when upgrading to the free Windows 10 offer. Instead activation is tied your PC's hardware (ex: motherboard/CPU/graphics card). If you do a clean install of Windows 10 on the PC in the future, the activation server will detect the registered PC and activate.
Can I reinstall Windows 10 on my computer after upgrading with free upgrade?
Once you’ve upgraded to Windows 10 using the free upgrade offer or Media Creation Tool on an activated Windows 7 or 8.1 PC, you will be able to reinstall, including a clean install, on the same device. You won’t need a product key for re-activations on the same hardware. If you make a meaningful change to your hardware, you may need to contact customer support to help with activation. You’ll also be able to create your own installation media like a USB drive or DVD, and use that to upgrade your device or reinstall after you’ve upgraded.
