Windows 10: Windows 10 me original key aur OEM key me kya difference hai

OEM key and original key

:)

 

Windows 7 OEM key

Hope this is not against the rules. If you do a clean install of Windows 10, it may, (has for me) accept a Win 7 OEM key and activate.

 

my windows 10 oem didn't come with a product key

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.

indeed OEM's have embedded keys a OEM upgrade is for machines with OEM copies and DO NOT COME WITH A KEY! sadly many vendors confuse the two because pre-windows 10 'OEM" came with a key
a end user should always buy a Retail OR "System builder OEM" copy when it comes to windows 10 system builder is not `OEM` you can blame microsoft for the retarded terminology screw up

it sounds like the op bought a pirated copy with no key microsoft does not ship windows 10 on optical disks .... they use flash drives
