It's probably best to upgrade to Win 10 using your 7 or 8/8.1 key or assistive technology upgrade if you qualify. It's hard to get a genuine retail Win 10 key for a discount. Even if you upgrade from a retail Win 7 or 8/8.1 it becomes tied to the machine. I bought a sealed boxed retail Win 10 on eBay and it turned out to be fake. It had an OEM key and the USB was missing the hologram.
