Windows 10: I cant activate my Windows key even though its a legit oem one so why is this happening to me?

My mom bought me a legit OEM Windows key so I tried to activate it but it refused to activate. Showing me various errors so I used VBS commands to try to activate it but it showed a 0xCOO4CCO3 error. So I did troubleshooting and it just said "We were not able to activate Windows on this device". I wanted to get Microsoft help but I live in Bangladesh so I could not call them. Instead, I saw several posts about, many YouTube videos but still no solutions. This is my last hope please help me. PLEASE

:)

 

activate windows 7 oem key

There is no difference between the OEM disc and the Retail disc with Windows 7. A retail disc will accept a OEM or Retail key, and vise versa.

If the OEM Key wasn't going to work with the disc you have, it would have stopped you during the install when it first asked you for the key, not during activation.

What is likely the problem is that, since the OEM version has already been activated once, it is failing activation again. Activate it over the phone using the option given to you on the failed activation screen, and you shouldn't have a problem activating it.

You cannot activate a retail version of Windows with an OEM key.
The retail version should have it's own activation key.
If you just borrowed the Win DVD from someone who is using the key, that won't work with your OEM (OA) key.

pwned by newtekie. lol My bad.
It does work in Vista and 7, just not in XP.

Have you looked on the ASUS website to see if you can re-download the driver/diag disk, or at least everything you need to make one?
