Need to know which parameters were actually passed to your function? $PSBoundParameters has you covered. It’s a built-in dictionary that only includes parameters explicitly provided by the caller. This makes it perfect for clean logic, dynamic behavior, or smart defaults—no need to check for $null or rely on default values. If a key exists in $PSBoundParameters, you know the user meant to pass it.

PowerShell is a powerful and versatile scripting language that is very useful for automating processes. I often look for how others have solved a particular problem. I want to share some, not all — sorry– :), handy tricks that I have collected over time with you here. They are not complete scripts but rather a collection of useful snippets that you can use in your own scripts. Most examples come from the PowerShell community, and I have gathered them here for you. I hope you find them helpful.

In this blog post, we explore optimizing parallel execution in PowerShell by reusing threads. By leveraging ConcurrentQueue and ForEach-Object -Parallel, we can significantly improve performance for time-intensive tasks. This method reuses threads instead of creating and removing them each time, resulting in faster execution. We provide a detailed example of pinging IP addresses to demonstrate the efficiency of this approach. Whether you’re new to multi-threading or looking to enhance your scripts, this guide offers valuable insights and practical tips.

In this blog post, we explore the power of Foreach-Object -Parallel in PowerShell to enhance performance for intensive tasks. By leveraging parallel execution and optimizing the use of variables, we can significantly reduce runtime and improve efficiency. We provide practical examples, including the use of ThrottleLimit and handling variables in parallel, to demonstrate the benefits and considerations of this approach. Whether you’re new to parallel execution or looking to refine your scripts, this guide offers valuable insights and techniques.
