Introduction
This article explains how to get the installed Software details of your
system. Here I will get the information from the Win32_Product class.
What Win32_Product is
The Win32_Product WMI class represents products as they are installed by Windows Installer. A product generally correlates to one installation package.
Design
Create a new Windows Forms Application Project.
Add one button control and one DataGrid to the form.
Design your screen as in the following screen:
![]()
Next add a reference for "System.Management".
To add the reference use the following procedure.
Go to Solution Explorer, select the project and right-click on that and choose
"Add Reference" from the menu.
![]()
A window will open; in that choose the ".Net" tab.

It will show a list. In that list, choose "System.Management" and click the "OK"
Button.

Now go to code view
Add the namespace "using System.Management;".
Write the following code in the Button Click event:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Management;
using System.Globalization;
namespace GetSoftwareDetails
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void
button1_Click(object sender, EventArgs e)
{
DataTable dt = new
DataTable();
dt.Columns.Add(new DataColumn("Name",
typeof(string)));
dt.Columns.Add(new DataColumn("InstallLocation",
typeof(string)));
dt.Columns.Add(new DataColumn("Instal
Date", typeof(string)));
dt.Columns.Add(new DataColumn("InstallState",
typeof(string)));
dt.Columns.Add(new DataColumn("Vendor",
typeof(string)));
dt.Columns.Add(new DataColumn("Version",
typeof(string)));
dt.Columns.Add(new DataColumn("PackageName",
typeof(string)));
dt.Columns.Add(new DataColumn("InstallSource",
typeof(string)));
dt.Columns.Add(new DataColumn("Language",
typeof(string)));
dt.Columns.Add(new DataColumn("LocalPackage",
typeof(string)));
dt.Columns.Add(new DataColumn("PackageCache",
typeof(string)));
dt.Columns.Add(new DataColumn("PackageCode",
typeof(string)));
dt.Columns.Add(new DataColumn("HelpTelephone",
typeof(string)));
dt.Columns.Add(new DataColumn("AssignmentType",
typeof(string)));
dt.Columns.Add(new DataColumn("Caption",
typeof(string)));
dt.Columns.Add(new DataColumn("Description",
typeof(string)));
dt.Columns.Add(new DataColumn("IdentifyingNumber",
typeof(string)));
dt.Columns.Add(new DataColumn("ProductID",
typeof(string)));
dt.Columns.Add(new DataColumn("RegOwner",
typeof(string)));
dt.Columns.Add(new DataColumn("RegCompany",
typeof(string)));
dt.Columns.Add(new DataColumn("SKUNumber",
typeof(string)));
dt.Columns.Add(new DataColumn("Transforms",
typeof(string)));
dt.Columns.Add(new DataColumn("URLInfoAbout",
typeof(string)));
dt.Columns.Add(new DataColumn("URLUpdateInfo",
typeof(string)));
dt.Columns.Add(new DataColumn("HelpLink",
typeof(string)));
dt.Columns.Add(new DataColumn("WordCount",
typeof(string)));
SelectQuery Sq = new
SelectQuery("Win32_Product");
ManagementObjectSearcher objOSDetails = new ManagementObjectSearcher(Sq);
ManagementObjectCollection osDetailsCollection =
objOSDetails.Get();
foreach (ManagementObject
MO in osDetailsCollection)
{
DataRow dr = dt.NewRow();
dr["Name"] = MO["Name"].ToString();
dr["AssignmentType"] = MO["AssignmentType"].ToString();
dr["Caption"] = MO["Caption"];
dr["Description"] = MO["Description"];
dr["IdentifyingNumber"] =
MO["IdentifyingNumber"];
dr["InstallLocation"] = MO["InstallLocation"];
var newDate = DateTime.ParseExact(MO["InstallDate"].ToString(), "yyyyMMdd", CultureInfo.InvariantCulture);
dr["Instal Date"] =
newDate;
dr["InstallState"] = MO["InstallState"];
dr["HelpLink"] = MO["HelpLink"];
dr["HelpTelephone"] = MO["HelpTelephone"];
dr["InstallSource"] = MO["InstallSource"];
dr["Language"] = MO["Language"];
dr["LocalPackage"] = MO["LocalPackage"];
dr["PackageCache"] = MO["PackageCache"];
dr["PackageCode"] = MO["PackageCode"];
dr["PackageName"] = MO["PackageName"];
dr["InstallState"] = MO["InstallState"];
dr["ProductID"] = MO["ProductID"];
dr["RegOwner"] = MO["RegOwner"];
dr["RegCompany"] = MO["RegCompany"];
dr["SKUNumber"] = MO["SKUNumber"];
dr["Transforms"] = MO["Transforms"];
dr["URLInfoAbout"] = MO["URLInfoAbout"];
dr["URLUpdateInfo"] = MO["URLUpdateInfo"];
dr["Vendor"] = MO["Vendor"];
dr["WordCount"] = MO["WordCount"];
dr["Version"] = MO["Version"];
dt.Rows.Add(dr);
}
dataGridView1.DataSource = dt;
}
}
}
In the code above I am getting the information from
Win32_Product Store the data into a data table and showing it in a DataGrid on a button click.
SelectQuery
It represents a WQL (WMI Query Language) SELECT data query.
ManagementObjectSearcher
It retrieves a collection of management objects based on a specified query.
This class is one of the more commonly used entry points to retrieving
management information.
ManagementObjectCollection
It represents various collections of management objects retrieved using WMI.
Now build your application. Click on the button; just wait for 2 minute it will show the installed Software details.

Thank you.
