Since the Win10 Upgrade fails on my HP DV6 notebook, I decided to do a clean install.
But now, it won't take the Win7 product key for activation!!
I called MS and they told me that a clean-install will NOT activate using Win7 product keys and that I have to purchase a product key.
I got this same story from two different MS reps.
I thought you COULD activate a clean-install using Win7 key using build 10586.
What is going on here?
