What is Windows PowerShell?
Windows PowerShell is a powerful command line tool and scripting platform created by Microsoft. It helps users automate tasks, manage Windows systems, control files, configure settings, and run scripts more efficiently than the traditional Command Prompt.
Unlike the old Command Prompt, PowerShell is designed for system administration and automation. It uses commands called cmdlets that allow users to perform complex tasks with simple instructions. Whether you are a beginner, IT student, developer, or system administrator, learning PowerShell can save hours of manual work.
