Windows PowerShell Scripting and Toolmaking

Build the tools that will allow you to better administer your Windows server and client products.

GK# 6544 Vendor# M55039

Course Overview


In this course, you will learn to build reusable tools by using Windows PowerShell 5.0/5.1. This course focuses on the Windows PowerShell scripting language and on the concepts and techniques needed to design tools, including and output requirements and functional requirements. You will learn functions to deal with anticipated errors using standard PowerShell patterns and practices. By course completion, you will be armed with the knowledge and skills to better administer a wide variety of server and client products and technologies that offer Windows PowerShell integration, including Microsoft Exchange Server, Microsoft Windows Active Directory Domain Services, Microsoft SharePoint Server, and more.

I just completed the Global Knowledge course on Windows PowerShell Scripting and Toolmaking. Fantastic course, entirely met all of my expectations for what I would get. I feel like I have the necessary to build my own tools for my team in PowerShell now, I just need to exercise what I’ve learned.

The GK instructor was excellent, really knew what he was doing. He was a good speaker—kept things entertaining but focused. He knew the material at such a depth that if people got hung up, he was always able to help them understand the material by explaining it in different ways, showing different methods of attaining the same result, and all ways of demonstrating mastery of the material.

GK uses Zoom now for their remote learning platform, and that was stable and clear the entire time. I never lost connection to the course during the entire 5 days, it never crashed or garbled the instructor’s words—really great choice for this. The Labs were a little inconsistent early on in day 1, but once we got on they remained available and were configured in such a way that the course materials worked in that environment exactly as expected every time.

All around excellent experience. I would highly recommend the course to anyone looking to take a deep dive into building tools with PowerShell.
