Windows 10: Windows de-actived, and won't re-activate. I own a product key.

Hello. I restarted my computer, and noticed a message in the bottom right corner that Windows isn't activated. When I went to settings, I got the following message: "we can't activate Windows on this device because you don't have a valid digital license or product key. If you think you do have a valid license or key, select Troubleshoot below. (0xc004c003)"


First, "troubleshoot" doesn't work. Second, I do own a valid product key. I have an e-mail receipt with my order number and product key. Third, I tried calling support and--as far as I can tell--the only way I can talk with a real person is if I PAY to do so. When I said I didn't want to pay, the call terminated.


So, to re-cap: I own a product key. Windows won't let me re-activate it unless I buy another product key, which I shouldn't need; or, pay to get support. This is ridiculous. Can anyone here help me?

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.

Windows 8.1 pro + WMC key activation

So it will be fine installing 8.1 pro with a KMS key, then switch to my 8 pro key and it will activate ok?

Maybe a daft question but why can't you just install 8.1 pro with the 8 pro key, or is it different keys for 8 and 8.1? seems silly when 8.1 is a free update anyway.
