Powershell

What is PowerShell?

PowerShell is a task automation and configuration management framework built by Microsoft. Unlike traditional command-line interfaces, PowerShell works with objects rather than plain text — meaning you can pipe structured data between commands, filter it, sort it, and manipulate it in ways that batch scripting simply can’t match.
It was built from the ground up for system administrators and engineers who need to manage infrastructure at scale — from a single server to thousands of machines.

Why PowerShell Matters

The real power of PowerShell isn’t running one-off commands — it’s automation. Tasks that would take hours of manual clicking through GUIs can be reduced to a script that runs in seconds, scheduled, logged, and repeated consistently.
Whether it’s creating 500 Active Directory user accounts, pulling health reports from all your servers, or automating patch compliance checks — PowerShell handles it cleanly.

Key strengths

• Managing Active Directory users, groups and policies
• Azure and Microsoft 365 administration
• Windows Server configuration and health monitoring
• Registry and file system operations
• Network diagnostics and reporting
• Integrating with REST APIs

Windows PowerShell vs PowerShell 7

Windows PowerShell (5.1) is the version built into Windows. It ships with every modern Windows installation and will never be updated beyond version 5.1 — Microsoft considers it complete. It runs exclusively on Windows and has deep integration with the .NET Framework. For most traditional Windows Server and Active Directory work, 5.1 is still the go-to version.

PowerShell 7 is the modern, open-source successor built on .NET Core. It runs on Windows, Linux, and macOS, receives active development and new features, and is the future of PowerShell. It introduces better error handling, parallel processing with ForEach-Object -Parallel, improved pipelines, and cross-platform compatibility.
The key thing to know is they can coexist on the same machine — and some modules only work in 5.1 while newer ones are optimized for 7. As an engineer working across environments, knowing both is essential.

The PowerShell posts here focus on real-world use cases — scripts I’ve actually used in enterprise environments and my homelab. No filler, no hello world examples. Expect content around Active Directory automation, user and group management, server health reporting, and building reusable script modules.
