In PowerShell, administrative tasks are generally performed by cmdlets, which are specialized .NET classes implementing a particular operation.
These work by accessing data in different data stores, like the file system or registry, which are made available to PowerShell via providers.

The Windows PowerShell Integrated Scripting Environment (ISE) is a host application for Windows PowerShell.
In Windows PowerShell ISE, you can run commands and write, test, and debug scripts in a single Windows-based graphic user interface
with multiline editing, tab completion, syntax coloring, selective execution, context-sensitive help, and support for right-to-left languages.
In addition to the PowerShell ISE, PowerShell is also well-supported in Visual Studio Code.
Furthermore, the ISE is not supported with PowerShell Core, while Visual Studio Code is supported for PowerShell Core on all platforms (Windows, macOS, and Linux).

The Windows PowerShell design integrates concepts from many different environments.
Several of them are familiar to people with experience in specific shells or programming environments, but very few people will know about all of them.
Looking at some of these concepts provides a useful overview of the shell.
- Viewing Object Structure
- Object Pipeline
- Using Format Cmdlets to Change Output
- Export Data with Out Cmdlets
- Using Variables to Store Objects
- Working with the Object cmdlets: Where-Object, Foreach-Object, ...
Working with Objects
PowerShell provides full access to COM, WMI and .NET, enabling administrators to perform administrative tasks on both local and remote Windows systems.
- Files and Folders
- Registry Keys and Values
- COM Objects
- WMI Objects
- .NET Objects
- Static Classes
Extending PowerShell Functionality
A module is a set of related Windows PowerShell functionalities, grouped together as a convenient unit (usually saved in a single directory).
By defining a set of related script files, assemblies, and related resources as a module, you can reference, load, persist, and share your code much easier than you would otherwise.
PowerShell Package Manager allows you to find, install and remove software all from within PowerShell from various repositories on the Internet and without having to search around the Internet or your network to find software installers.

- PowerShell Profiles

The execution policy is part of the security strategy of Windows PowerShell.
It determines whether you can load configuration files and run scripts, and it determines which scripts, if any, must be digitally signed before they will run.

- Security Sensitive Information in Scripts
Windows PowerShell includes a dynamically typed scripting language which can implement complex operations using cmdlets imperatively.
The scripting language supports variables, functions, branching, loops, structured error/exception handling and closures/lambda expressions, as well as integration with .NET.
- While – do while – do until
- If - Switch
- Break - Continue
Managing Your Environment
The goal of PowerShell is to ease your work as an administrator. In this module we will talk about basic management tasks that you need
to perform and how you can accomplish this through PowerShell.
Configuring network settings, settings security on files and folders, managing Active Directory.
- File Shares
- Data Import
- Server Management
- Active Directory
Jobs are long-running tasks that are executed in the background. You don't have to wait for the job to finish and can perform other tasks while the job is running.
Once completed, the job output can be retrieved. Jobs can be executed on a remote system or they can be scheduled.

- Remoting Jobs

PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and associated scripting language.
Initially a Windows component only, known as Windows PowerShell, it was made open-source and cross-platform in 2016 with the introduction
of PowerShell Core. The former is built on .NET Framework while the latter on .NET Core.
Today, PowerShell can be used to manage and deploy all your server workloads, Windows or Linux, on-prem or cloud.
This course is based on Windows PowerShell 5.1 and PowerShell Core 6.0.
This course will get you acquainted with all the different features of Windows PowerShell. You will learn how to customize the PowerShell environment to your needs and how to automate and script administration, configuration, monitoring and deployment of
Windows based servers and applications with out of the box cmdlets and custom scripts.
