Windows 10: Windows 10 Activation Error code: 0x8004FC12

Hi,

I recently upgraded my Dell Inspiron Laptop to Windows 10 Home from Windows 8.1 Home via Microsoft's media creation tool. I downloaded it onto a flash drive and used that to perform a clean installation. However, after the installation my laptop showed that Windows 10 hasn't been activated along with the error code 0xC004C003. I then reset my PC as suggested by some people. When I went back into the activation settings, it still displayed "Windows is not activated." There was an activate button though, which wasn't there before, but when I clicked on it, it said, "Windows can't activate. Try again later." When I clicked on error details, it displayed "Error code: 0x8004FC12" with no description.





Does anyone know why this is showing up? And if so, how can I fix it?
Thanks!

:)

windows 10 cant activate

I have recently upgraded my windows 8.1 to 10 and it is working well. But account is not getting activated. Error code: 0x8004FC12. After pressing activate button message appears 'windows can't activate try later'. It was activated with USB media tool.

 

You cannot do a clean installation without 1st upgrading your OS directly with the media creation tool. Once you have upgraded, then you may do a clean installation.

Then should I reinstall Windows 8.1, then follow the steps you described?

 

Yes, reinstall or revert back to 8.1, follow the steps in the tutorial to upgrade, then follow the steps in the next one to do a clean install. Option 2 on this tutorial will work well. I did the same thing BTW, d/l ed an ISO, upgraded via disk & couldn't activate due to not upgrading 1st.
