Get List of Installed Software in Local Machine using C# Code

Here, I will explain how to get the list of installed software in a local machine.

Step 1: Drag and drop Listbox control to Window Forms form and also drag and drop Label control on to the form.



Step 2: For this you need to add the following NameSpace in your code.

using Microsoft.Win32;

Step 3: Then Add this code

public void GetInstalledApps()

{

string uninstallKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";

using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(uninstallKey))

{

foreach (string skName in rk.GetSubKeyNames())

{

using (RegistryKey sk = rk.OpenSubKey(skName))

{

try

{

listBox1.Items.Add(sk.GetValue("DisplayName"));

}

catch (Exception ex)

{ }

}

}

label1.Text = listBox1.Items.Count.ToString();

}

}

Step 4: Then Call This method in the Window Forms Constructor.

public Form1()

{

InitializeComponent();

//Call this GetInstalledApps in Window Forms Constructor.

GetInstalledApps();

}

Step 5: Run your application and see that the output looks like this and also observe the number of software installed in your local machine.
