Checking ports on a Windows system involves identifying the ports that are open and listening for incoming connections, along with the associated processes or applications using those ports. This information is essential for network troubleshooting, security audits, and managing network resources effectively.
Understanding port usage provides valuable insights into the system’s exposure to potential vulnerabilities, the types of services accessible externally or internally, and the overall network configuration. Moreover, it helps detect unauthorized access attempts, identify resource-intensive applications, and optimize network performance by freeing up unused ports.
