What Is PDQ Inventory?
PDQ Inventory is an inventory and system information tool from PDQ that scans computers and collects information about their hardware, software, and Windows configuration. The collected information can then be viewed from the PDQ Inventory console or used to generate reports.
PDQ describes Inventory as a companion product to PDQ Deploy. It can also provide information that helps administrators determine which computers need particular updates or software deployments.
Instead of checking each computer manually, administrators can use PDQ Inventory to build a centralized view of computers on their network.
Key Features of PDQ Inventory

For remote scanning, make sure that the target computers and network infrastructure satisfy PDQ’s requirements. Administrative access, DNS functionality, and appropriate Windows firewall settings can be important for remote communication.
How to Add Computers to PDQ Inventory
Before collecting inventory information, computers need to be available to PDQ Inventory.
Administrators can add computers individually or use organizational methods such as Active Directory synchronization, depending on their environment and configuration.
Once computers have been added, administrators can configure scanning and select appropriate inventory profiles.
PDQ Inventory’s computer interface can display information gathered by scanners such as Computer Details, Active Directory, and Network Adapters.
How to Scan Computers with PDQ Inventory
Scanning is one of the main functions of PDQ Inventory.
A typical workflow involves:
- Add or discover the target computer.
- Confirm that the computer is available.
- Make sure required permissions are configured.
- Select the appropriate scan profile.
- Start the inventory scan.
- Wait for the scan to complete.
- Open the computer details.
- Review the collected information.
PDQ Inventory can then display information collected by the configured scanners.
If scanning fails, administrators should first check connectivity, DNS, administrative permissions, Windows Firewall configuration, and file-sharing access.
Hardware and Software Inventory
One of the most useful purposes of PDQ Inventory is maintaining a centralized view of hardware and software.
For hardware, administrators can investigate computer specifications and identify machines that meet particular hardware criteria.
For software, administrators can identify installed applications and use that information to create collections or support deployment decisions.
For example, an IT administrator could create a collection containing computers that have a particular application installed and then use that collection when planning a software update.
Creating Collections in PDQ Inventory
Collections allow administrators to organize computers according to predefined or custom conditions.
A static collection can contain computers selected manually, while a dynamic collection can use rules to determine which computers belong to it.
Examples of useful collections include:
- Windows 11 computers
- Computers with a specific application
- Computers missing a particular application
- Systems with a specific hardware configuration
- Computers in a particular department
- Machines requiring a software update
PDQ Inventory’s free mode includes static and dynamic collections.
Using Custom Scanners
PDQ Inventory provides scanners for collecting different types of information. Administrators with more advanced requirements can configure additional scanning methods.
Custom scanners can be useful when an organization needs to collect information that is not available through its standard inventory setup.
Before creating custom scanners, administrators should understand what information they need and how that information will be used in reports or collections.
Managing Windows Updates and Installed Software
Inventory information can help administrators understand which computers have particular software or Windows configurations.
This is particularly useful before performing large-scale software deployments or maintenance operations.
PDQ Inventory is integrated with PDQ Deploy, allowing inventory collections to help determine deployment targets. PDQ documents the ability to link PDQ Deploy target lists to collections created in Inventory.
For example, an administrator could use an inventory collection to identify computers with an older application version and then use that collection as part of a deployment workflow.
Reports and Data Export
Reports provide a structured way to present inventory information.
An IT administrator can use reports to answer questions such as:
- Which computers have a particular application?
- Which systems are running a particular Windows version?
- Which machines have specific hardware?
- How many computers are included in a particular collection?
- Which computers require further investigation?
PDQ Inventory’s feature documentation lists prebuilt inventory reports among the capabilities available in its free mode.
PDQ Inventory and Remote Management
PDQ Inventory is more than a basic hardware information utility. Depending on the edition and configuration, it can provide additional management functionality.
