Course Objective & Scope

Clicking through GUIs across hundreds of servers or user accounts wastes hours and invites human error. This course teaches how to use PowerShell's object-oriented pipeline to build repeatable automation across Windows, Linux, Active Directory and cloud environments.

Cmdlets and the object pipeline, filtering and grouping, CIM/WMI queries, PowerShell Remoting over WinRM and SSH, handling JSON/CSV and REST APIs, `try/catch` error handling, advanced parameterised functions, module packaging and script signing are practised hands-on. Participants turn one of their routine administrative tasks into a reusable PowerShell module.

Who Should Attend?

  • System administrators managing Windows Server, Active Directory and endpoints
  • DevOps and cloud engineers writing CI/CD and cloud automation
  • Microsoft 365 specialists automating bulk user, licensing and reporting tasks
  • Prerequisite: basic operating system administration experience

Key Takeaways

  • Filter, transform and export data through the object pipeline instead of brittle text parsing
  • Manage dozens of remote servers in parallel using CIM/WMI and PowerShell Remoting
  • Automate bulk tasks across Active Directory, Microsoft Graph and REST APIs
  • Write resilient scripts with parameter validation, `-WhatIf`/`-Confirm` support and error handling
  • Package scripts into reusable modules and secure them with Execution Policies and SecretStore

Curriculum

PowerShell Architecture and the Object Pipeline
  • Differences between Windows PowerShell 5.1 and cross-platform PowerShell 7
