Applies to: Windows PowerShell 5.0.10586, 5.1.14385.0, PowerShellGet 1.0.0.1 The Import-Module cmdlet, the #Requires directive, and module auto-loading (PS 3.0+) all import modules into a PowerShell session. But, which modules do they import by default? It’s an important question when you are writing shared code that uses commands from other modules. And, the answer has become […]

Using a ModuleSpecification Object
With the advent of side-by-side module versions in Windows PowerShell 5.0, the lovely, but obscure ModuleSpecification object has become your new best friend. Use it to make sure that the commands and module that you use are the ones that you intend. Using ModuleSpecification Let’s start with an example. I want to get the Expand-Archive […]
Which PowerShell Versions are Users Running?
In March 2016, SAPIEN Technologies, Inc. posted a survey asking users and administrators which versions of Windows PowerShell they’re running. We got 148 responses by the April 8 when we closed the survey. This blog post reports the findings. While reading them, please keep in mind that this is not a statistically valid survey. We […]
Use PSScriptAnalyzer in PowerShell Studio
Applies to: Windows PowerShell 3.0 and later PSScriptAnalyzer 1.1.0 and later PowerShell Studio 5.2.118 and later PowerShell Studio has long supported best practices in Windows PowerShell, including running and debugging without profiles, avoiding cmdlet and parameter aliases (right-click\Expand to cmdlet, Expand all aliases: Ctrl+Shift+A), using consistent formatting to make maintenance and debugging easier, and using […]
Inheritance in PowerShell Classes
If you’re learning about classes in Windows PowerShell 5.0, one of the first new concepts that you’ll encounter is inheritance. When you create a class that is based on another class, your new subclass or child class automatically gets the inheritable members (e.g. properties and methods) of the parent class or base class. Inheritance is […]
Which versions of PowerShell do you run?
The PowerShell team released Windows PowerShell 5.0 on Windows 10 last year and just re-released Windows Management Framework (WMF) 5.0 for earlier versions of Windows. But, we know from years of experience that many people don’t upgrade their versions quickly. It takes time to get to know and trust a new version. In a large enterprise, it […]

Update-Module 5.0 adds, not updates
Applies to: — Windows PowerShell 5.0.10586.63 — PowerShellGet 1.0.0.1 I’m a huge fan of sharing Windows PowerShell modules and making them easy to find (Find-Module), view (Save-Module), and install (Install-Module). So, I truly love the new PowerShellGet module. However, you really need to understand how it works before you use it. Otherwise, you might end up […]
Using Prefixes to Prevent Command Name Collision
In January, I had the honor of presenting to the Mississippi PowerShell User Group (MSPSUG). I’ve known the organizers, Mike Robbins and Rohn Edwards for years, and truly respect them. The PSUG is online-only, which makes it a challenge for presenters, but they attract a very sophisticated audience, so my talks there are really conversations. […]
Using Group-Object to Detect Command Name Conflicts
The Group-Object cmdlet, one of the original provider cmdlets, is as old as Windows PowerShell. It was introduced in version 1.0 and hasn’t changed at all since then. But, it is one of my favorites. (You can tell when I love a cmdlet by the number of examples. Group-Object has 9!) In fact, when you use it […]
