Using Windows with limited features even after having a licensed product key can be really frustrating at one point. Since the validation fails, you will not be able to experience every feature of the current operating system. Just when you make an attempt to do so, error code 0xc004f074 often prompts and obstructs the activation process. Once you have upgraded to Windows 11 or 10, you are supposed to activate the Operating System with a legitimate license key.
