Hello, i want to know your opinions about a problem that so far i didn't find any solution to solve it. I make an upgrade from Windows 7 Pro (activate successful with windows loader by daz, in other words my windows was genuine), to Windows 10. The new version of windows 10 was succesffuly instaled, but when i want to see if this copy of windows was activated, i have encountered this error: (null) Error Code: 0xC004F012. For this error i didn't find any support in Microsoft frequently error in which regard Windows 10 instalation. The last solution that i thought is to try to activate with KMSpico 10.1.2. Not work, windows is still not activate. What are your advices, what should i do. For now i want to not take in consideration a clean install.
