Windows 10: I didn't receive the product key to activate copy of Windows 10 Pro

I purchased and installed the upgrade license from Microsoft Windows10 Home OEM to Windows10 Pro, I didn't receive the product key to activate copy of Windows 10 Pro

Dude, go to Newegg right now and read the questions and answers tab on Windows 10 OEM. The OEM copies that are listed there DO in fact, come on an optical disc. The flash drive ONLY comes on Retail copies.

LOL yes they do. Legit OEM copies DO come with a key - on a sticker that you affix to the case. OEM and SLP (System Locked Preactivation) are NOT the same thing. SLP is what large OEMs like Dell, HP, etc do, where every system came out of the factory activated with the same "Manufacturer's Master" key in XP, Vista, and 7. Reinstalling with the factory image preserves this activation. However if you dig that key out with Magical Jellybean and try to do a clean install with it, activation will fail. That's why every machine that came out of a factory ALSO had a COA with a unique key. That is what you need to use for a clean install. Starting with 8, large OEMs began embedding the unique key into the BIOS, which is why they no longer come with a unique key sticker. However, you can still buy legit OEM versions of every version (the ones that small shops would use for their custom machines) - including 10 - which come with the sticker with a unique key.

The only differences between OEM and Retail versions is that the OEM version locks to the first motherboard it is activated on, while Retail can be moved to a different one. OEM also come with no support.

windows 10 can also activate solely based on HWID no key required how do you think the microsoft store activation works it installs a generic key and activates based on hwid
