Cannot Activate Windows. Followed Windows instructions to reinstall Windows 10 Pro on 64-bit PC. Windows reinstalled, but it was Windows Enterprises that was reinstalled. Message appeared that Windows was not activated with error code 0xC004F213. Messages appeared to contact System Administrator. Well, I am the only one who uses this PC and the only one who uses Office 365, so I am the System Administrator. Need help to activate Windows.
The error code 0xC004F213 means there is no product key in the system, you have to navigate to Settings and go under Update & Security and click on Activation and then select Change product key and then enter your product key.
I already did that. I've checked all protocols to activate Windows. NONE has worked. I know I had an activated Windows 10 Pro because I had always been able to personalize my PC. I had to reinstall the Windows 10 Pro. I followed Microsoft's own protocol exactly to reinstall Windows using the same Windows 10 Pro on my PC. Windows 10 did reinstall, but it was Windows 10 Enterprise that was reinstalled, not the Windows 10 Pro that was on my PC. Then suddenly, a message appeared that the Windows 10 Enterprise needed to be "activated". I also have a subscription to Microsoft 365 (formerly Office 365) and I am the Administrator. Again, NOTHING has worked to get the Windows activated.
