Explanation:
To reduce the attack surface area and to make sure you are not affected by undiscovered service vulnerabilities, disable any service that is not required Because Server Core has fewer system services running on it than a Full installation does, there's less attack surface (that is, fewer possible vectors for malicious attacks on the server). This means that a Server Core installation is more secure than a similarly configured Full installation.
