Windows 10: Windows Activation Key Not Working

So I just recently found my activation key. I put it into both the store product key as well as the 'change product key' but neither would except my activation key, giving me this error message 'The product key you entered didn't work. Check the product key and try again, or enter a different one 0xc0020036'. I have put it in at least 5 times now and I am positive I didn't misplace any numbers or letters. I looked online for several discussion boards on the same topic and have tried what has been suggested but it didn't work, most of them required me to run SLUI 4, however I couldn't find any SLUI 4, only SLUI. I have also tried updating windows several times but with no result. I am really wondering what I can do about this because the 'Activate Windows' watermark is really getting on my nerves as of recently.

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.

 

activate windows 7 oem key

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?

 

Windows 8.1 pro + WMC key activation

This worked for me last time with a Win 8 key.

Install Windows 8.1 and enter KMS key during setup. Once in windows change product key to my Windows 8 key. Go to add features and enter my WMC add-on key. Drink a beer to a job well done.
