InstalledPackagesView

InstalledPackagesView is a specialized, portable freeware tool developed by NirSoft that enumerates every software package installed on your computer specifically via the Windows Installer (MSI) engine. It extracts deep system data that standard Windows “Apps & Features” screens hide, including hidden dependencies, full local paths, and associated registry hives. Core Interface Layout

The utility uses a highly efficient, dual-pane layout designed for rapid inspection:

Upper Pane: Displays a comprehensive list of all installed MSI packages discovered on the system.

Lower Pane: Automatically populates with the underlying technical footprint of the software package highlighted in the upper pane. This includes associated files, Registry keys, and .NET Assemblies. Windows Installer Details Revealed

For every individual package identified, the tool extracts and parses numerous granular data points from the Windows registry:

Display Name & Version: The user-facing software identification metadata.

Install Date & Registry Time: Precise timestamps indicating exactly when the software was introduced to the operating system.

Estimated Size: Total storage space occupied by the installation payload.

Install Location: The target absolute file directory where the software’s active executables reside.

Install Source: The exact source path (such as a temporary folder or network drive) from which the original setup file was launched.

MSI Filename: The randomized, cached .msi file title assigned inside the hidden system cache folder (C:\Windows\Installer). Step-by-Step Guide to Using InstalledPackagesView 1. Download and Initialize

Navigate to the official ⁠NirSoft InstalledPackagesView Page. Download the lightweight ZIP package. Extract the contents into any folder.

Launch InstalledPackagesView.exe. (No administrative installation sequence or background agent is required). 2. Inspect an Installed Package

Scroll through or sort the alphabetical table within the Upper Pane.

Left-click once on any suspicious, broken, or standard program entry.

Look down into the Lower Pane to immediately inspect every file path modified, registry entry altered, and assembly file locked by that program’s installer. 3. Analyze External Drives or Remote Machines

Press the F9 key on your keyboard to instantly pull up the Advanced Options prompt.

Change the loading target from your local system to an External Drive or Remote Computer across a local network configuration.

Point the database path directly to the offline configuration folder if scanning an external drive (e.g., F:\windows\system32\config) to pull historical installer details off a dead operating system. 4. Export the Data for System Auditing

Highlight a single application row or select multiple entries using standard Shift/Ctrl keyboard modifiers.

Press Ctrl + S to launch the Save Selected Items dialogue screen.

Choose your preferred export file architecture—the system natively exports tabular data straight into structured CSV, XML, HTML, or JSON tables for easy processing.
