In this case, two other extension methods to resolve the error code 0xc004c003 are given below.

You should contact Microsoft after making changes to your hardware

Whenever a user activates Windows, the registration of the hardware configuration can be done through Microsoft’s activation server. There is an advantage to this approach. If someone needs to reinstall the Windows operating system, the product key is no longer required for activation, as the registration of the hardware is checked through digital verification. There is a problem with this process. This digital verification tends to stop whenever there is a change in the main part or assembly of the machine. As a result, Windows is no longer activated. Therefore, you should contact the Microsoft support team for detailed support.

Update the BIOS

How does Windows 10 fix error code 0xc004c003? One of the serious reasons why the Windows operating system fails to update is the BIOS. Please note that we do not recommend making any changes to the BIOS without proper knowledge. The state of the BIOS is directly related to the state of the system hardware. When the problem starts directly with the hardware or BIOS, the best way to fix the problem is to update the BIOS. Updating the BIOS has the potential to resolve not only the error code 0xc004c003 but equally likely to fix any issues that the system is facing due to the hardware. Additional features may also be added.

However, BIOS updates are more complicated and require special care. A slight mistake can cause permanent damage to the motherboard and entire circuitry. Although the process is risky, carefully following the right steps will ensure that the BIOS update is completed successfully. This is one of the core procedures for correcting system incompatibilities. Most users report that updating the BIOS successfully fixes the error code 0xc004c003.

No matter how unlikely, even after this, the error code 0xc004c003 may not be resolved. In such rare cases, it is advisable to seek professional Microsoft technical support services.
