Deploy modules that accept multiple values by inputting an array of computer names through the command line. Loop over each computer, connect, get information back, and produce verbose status updates.

Activate the pipeline in your module and enable functions to accept pipeline input, using pipeline by property name and a process block to loop through each computer name.

Expand your PowerShell module to retrieve operating system, computer system, and BIOS information, save results in variables, and build a structured output for multiple devices using a pipeline.

Learn to extend an in-house module with an advanced function that sets a service password on a computer, using whatif and confirm to preview and require confirmation with verbose output.

Design and implement a PowerShell function to set a service password with three parameters: computer name, service name, and new password, supporting what-if and confirm semantics and parameter validation.

Learn to automate setting service passwords across multiple computers in PowerShell, using pipelines, foreach loops, and what-if scenarios to validate changes before execution.

Discover how to use the .NET framework and REST API to extend PowerShell, build secret and custom modules, and deploy solutions when a command is not natively available.

Explore how the .NET framework is a collection of namespaces containing classes and APIs, with assemblies and a data link library delivering functionality for languages like C#, VB, and PowerShell.

Demonstrate nested loops in PowerShell to process multiple computers and their disks, leveraging modules and pipeline input to retrieve and display disk information.

Develop a nested PowerShell loop to collect per-device disk details, build a structured object with computer name, disk, free space, and size, and output a comprehensive report for domain controllers.

Deploy a PowerShell-based user interface by importing a module, looping a main screen menu, and routing choices to scripts, with execution policy checks.

PowerShell interface design for an options script focuses on prompting for computer names, calling functions, handling arrays, and looping to present a friendly report.

Build a PowerShell module to obtain network adapter details across multiple computers, gathering interfaces, IP addresses by interface index, and prepare to generate reports.

Create a PowerShell report by gathering disk and network adapter data and exporting it to a file on C drive. Use variables and functions to assemble fragments for multi-computer outputs.

Master PowerShell error handling by using try catch to detect and log terminating and non-terminating errors, and apply practical scripts for domain controllers and devices to manage errors effectively.

explains how PowerShell's error action preference controls script flow, defaulting to continue, with options to silently continue, suspend, or stop errors and handle offline devices.

Learn to use try catch in PowerShell to handle errors across multiple devices with verbose output, processing each device one by one and warning when a device is offline.

Master three techniques to capture and inspect PowerShell errors: the error collection, the -ErrorVariable option, and try/catch blocks, with examples showing logging and saving details.

Learn how to save error messages and computer information to a log file in a PowerShell module, using append mode and catch blocks to handle warnings when managing multiple computers.

Explore XML introduction and its data structures, comparing XML with Excel and JSON, and learn to read XML into memory, navigate with XPath, and edit elements and attributes.

Prepare your lab by editing the inventory XML file and setting up a PowerShell module to retrieve operating system, disk, and network adapter information for Victoria servers.

Demonstrate building and saving an XML sample in PowerShell, structuring a computers element with attributes like IP address and interface index, and retrieving specific values from the XML.

Discover how to use XPath with XML and integrate two kinds of scripts, guiding students who missed the previous course toward the same example.

Master an xpath demo in PowerShell 2019 by building a targeted query to extract Victoria's IP address and addresses. Save results to a variable and explore related properties and methods.

Connects the power module script with the XML main lab, updates the inventory using net IP inventory, retrieves adapter details for multiple devices, and saves results to inventory.xml.

Build a PowerShell lab that reads a server inventory from a file, iterates computers, and constructs an XML with addresses and IP address elements using the XML module.

Create ip address elements inside addresses for each network adapter, assign attributes (family, interface, adapter, ip address), then build and save the main inventory to the output path.

Explore json in Windows PowerShell, compare json with xml, and learn to convert from json and to json, creating PowerShell custom objects and saving json files through hands-on lab.

Learn to retrieve data from rest api in PowerShell and convert to and from json using ConvertTo-Json and ConvertFrom-Json. Build PowerShell custom objects for easy processing.

Query a website via rest api and json, retrieve data, and convert it to a PowerShell object. Save results to a file and expand nested properties to select fields.

Explore handling custom formatted data in PowerShell by building and applying regular expressions, converting strings to objects, and searching for data that matches the pattern.

Explore regular expressions to extract specific words or patterns from text, such as ip addresses or protocol names, and save the match to a variable for use in a pipeline.

Master regular expressions and quantifiers, including star, plus, and question mark, braces, and grouping for building precise patterns with alternation and character classes.

Master regular expression classes, dots, and flags to match digits, spaces, and word characters, extract devices starting with Victoria, and apply case-insensitive, global, and multiline options in PowerShell patterns.

Apply a regular expression in PowerShell to filter and extract specific records from server data, using variables, piping, and pattern matching to isolate entries containing Victoria.
