In the Microsoft Windows operating system, Services are special programs designed to perform essential tasks without user interaction. These programs run silently in the background, often starting automatically on system startup, and can have a significant impact on the system's functionality and security.

In this lab, we will explore the world of Windows Services, including how to manage and troubleshoot services using the Service Control Manager (SCM) and PowerShell. We will also learn about the potential security risks associated with Windows Services, including the unquoted service path attack, and how to identify and mitigate these risks.

Through this lab, we will gain hands-on experience with Windows Services and learn how to use PowerShell and the SCM to manage and troubleshoot services. We will also learn how to use the Windows Management Instrumentation Command (WMIC) to detect and exploit vulnerabilities in Windows Services.
