Announcing PowerShell Scanner additions in PDQ Inventory

PDQ Deploy and PDQ Inventory versions are now available for download. We've made some improvements to our already powerful PowerShell Scanner.

To enable alerts for newly released versions of PDQ products, click Options > Preferences >  Alerts (or press Ctrl+Comma) and select both Auto Update Check Enabled and Release Channel. Once saved, close preferences and the link should be in the status bar on the bottom right of your PDQ product.

PowerShell Scanner improvements

Version brought the PowerShell Scanner to PDQ Inventory and this upcoming release adds new features as well as general improvements. If you aren’t sure what the PowerShell Scanner is, there’s no time like the present to discover our most versatile scanner and the endless capabilities using PowerShell scripts. 

I can’t stress enough how this really is the scanner to end all scanners. Is there data you feel that Inventory is missing? Are you fluid in PowerShell scripting? Great! Get to scripting. Are you intimidated by PowerShell or just not a fluent scripter? No problem! We’ve got you covered as well with our Git repository of scripts that can be imported.

Haven’t used it yet? Navigate to Options > Scan Profiles. In this window, there are two built-in PowerShell scanners for your immediate use. PS - Mapped Drives and PS - Windows Defender Information. To create your own, click New. This will open the New Scan Profile - Scan Profile window. Select Add > PowerShell

Ever-expanding Git repository

The Git repository is expanding and we now have 20 scanners that you can import for your own use. If you aren’t familiar with Git, Colby has provided detailed instructions to get you started. Once you have it set up, importing scanners directly into Inventory is literally a few steps away. 

Have you created your own scripts that you would like to share? You too can contribute to the Git repository. Once your script has been reviewed and approved, it will be published and many others will thank you too! You will be credited as the author, so you’ll also be immortalized in the PDQ PowerShell Hall of Fame! Okay, okay. We really don’t have one, but we will definitely think highly of you.


The use of variables has been added to the PowerShell scanner. Variables can be used to store values that may be referenced throughout PDQ Inventory. They can be very handy when the same value needs to be referenced multiple times. These are available in the scanner for File, Script, Parameters, and Additional Files. Clicking on the variables button will allow you to choose from your own custom variables as well as those created by PDQ.

Variables in PS Scanner

Scan As settings

Individual Scan Profiles now include the ability to change the Scan As settings. These settings include the ability to scan as the Logged on User. In this mode, it attempts to execute scanners in Interactive mode as the user that is currently logged into the target machine. To access a Scan Profile, click Options > Scan Profiles. From here, you can either add a new scan profile or edit an existing one.

Scan As in Scan Profiles


PowerShell Scanners will display a tooltip in the parameters field if the script contains parameters. This shows you a list of the available parameters, as well as the type of data they accept. Once you have identified the parameters you want to use, simply type them into the Parameters field.
