What is PowerShell?
PowerShell is an advanced Microsoft command-line shell and associated scripting language. It integrates with the .NET Framework and provides an environment for execution of cmdlets, which are lightweight command-line tools for performing specific functions.

Before diving into the PowerShell coding, let’s understand its basics to get a fundamental foothold. PowerShell probably might appear complex at first glance, but it’s considerably simple once you get familiar with it.
You can access PowerShell through the Start menu or by typing ‘PowerShell’ into the seach bar. PowerShell ISE (Integrated Scripting Environment) is also available, which allows for scripting, testing, and troubleshooting.
Cmdlets are the most critical components of PowerShell. These are predefined scripts in PowerShell that perform a particular task. Each cmdlet has a Verb-Noun format, such as Get-Help, Set-ExecutionPolicy, and so on.
