I have recently upgraded my laptop drive running Windows 7 Home Edition. I reserved windows 10 free upgrade, however I installed Windows 10 Insider preview using ISO. Before I did that I created Recovery image using Packard Bell software. Since then I have replaced old drive with Sandisk 240gb SSD drive, I installed Windows 10 using ISO on SSD.
I have sticker on the back of my laptop with Windows 7 home edition key. When Windows 10 is officially released on 29/07 do I need to use the key on my laptop. Will it be as simple as that or Do i need to restore the image on SSD drive and then upgrade to Windows 10. I am hoping I don't have to install Windows 10 as a fresh install.
