Windows 10: Cheap Windows 10 Licence Keys.... OEM Keys

I have bought multiple laptops that have had OEM windows 10 packaged. I recently built my own pc and am wanting to activate windows 10. After looking on the Microsoft website I saw that the licenses are rather expensive, however, the trial version I have on my pc is perfectly fine and I have no need to actually activate obviously it would nice to. Despite this I thought I would look and found many sellers on Ebay, Gumtree, and other websites that claim to have working keys for life.


As I am in no rush to activate my trial I thought I would ask the official Microsoft forum. If say the product key did work and I was the first that the seller sold it to... would the product key end up getting blacklisted? If the product key was for OEM and I changed my hardware would Microsoft support be able to reactivate the product key for the new hardware? Also on a side note, I saw that in South Africa the licences are sold for R3 999,00 which is substantially cheaper than what it costs here in Australia.

Two OEM licence keys (different Windows versions) on one PC

Hello,
I'm in the process of building another PC and I want to know if it's possible for two versions of Windows to reside next to each other legitimately. I would have windows 7 and 10 as a dual-boot system. So if I buy OEM keys and activate them would one de-activate the other? I know that OEM licence keys are bound to the mobo and are irrevocable. Any advice is greatly appreciated. Thank you.

 

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

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
