Here's the situation: I own Windows 7 Ultimate, box version, with product key and all. But I DON'T HAVE IT INSTALLED.
I used my only system SSD to test Windows 10 Insider Preview.
I admit I used pirate KMS to activate it, since it refused to activate.
Now I installed official Windows 10 Pro, but it obviously doesn't activate. At least legally, because activating via pirate KMS still works, but it's not what I need. I'm entitled to free upgrade as legal, registered Windows 7 owner.
I've read I have to wipe my HD, install Windows 7, activate it, install ALL updates (which would take all day), then upgrade (and it would activate then).
Since I don't have whole day to waste for it - is there a shortcut? I'm looking for a way to use my Windows 7 product key to activate my Windows 10 upgrade. I'm positive it's possible, but it requires some magic. Any clues?
Here's my guess, when you do normal upgrade procedure you get new product key for Windows 10 based on the product key you had for previous Windows version. The old key has to be validated first. My question is: how to achieve it using only existing Windows 10 installation? Maybe I could install Windows 7 on virtual machine, activate it and somehow get the new product key from VM? Anyone tried that?
