Are you using a Windows 11 PC or laptop but not able to enjoy all the features of this operating system due to Windows being idle? Or receiving activation error during the activation process? If yes then first of all calm down as the solution of that problem is briefly described in this blog with a complete tutorial. There are many types of activation errors that can appear on newly installed Windows 11 PC or laptops. When the system is upgraded to Windows 11, the newly installed operating system will fetch all product key information and activation from the previous operating system. All the recovered information is then saved on a Microsoft server, along with your PC information. Activation error generally appears when a clean installation of Windows is done by the user for the first time.
Windows 11 Activation Error Codes and their solutions
Activating Windows 11 has become very easy. Either the key is anchored in the device (BIOS) and you don’t have to enter anything. Or for a new installation, you simply skip entering the key and the hardware ID automatically reactivates Windows 11. But it can of course also happen that the activation fails with an error message. The most common errors here are 0xC004C003 0xD0000272, 0xC0000272, 0xc004C012, 0xC004C013, 0xC004C014. You don’t have to worry here. Because only the activation server cannot be reached here. As soon as this is available again, Windows 11 will then be activated automatically.
