Windows PowerShell is a task automation and configuration management framework developed by Microsoft. It consists of a command-line shell and an associated scripting language, allowing users to automate repetitive tasks and manage system configurations efficiently. PowerShell is built on the .NET framework, which enables it to interact with various system components and applications. PowerShell uses cmdlets, which are specialized .NET classes, to perform specific functions. Users can combine these cmdlets into scripts to execute complex tasks. It is widely used by system administrators and IT professionals for managing Windows environments, making it a powerful tool for enhancing productivity and system management.
