**EDIT AGAIN FOR Windows Form**

Here's a complete listing, assuming you have a ListBox with an id of "lbKeys":

```
using Microsoft.Win32;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Linq;
using System.UI;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication2
{

    public partial class Form1 : Form
    {

        public Form1()
        {

            RegistryKey myKey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU");

            // Check to see if there were any subkeys
            if (myKey.SubKeyCount > 0)
            {
                foreach (string subKey in myKey.GetSubKeyNames())
                {
                    lbKeys.Items.Add(subKey);
                }
            }
        }
}

```

There may not have been any subkeys for the key you were looking at - under the previous code I gave you, the foreach loop wouldn't do anything because there was nothing to loop through.
Use OpenSubKey to open up Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU, and then call GetSubKeyNames to get the names of the subkeys. [Here](http://msdn.microsoft.com/en-us/library/microsoft.win32.registrykey%28VS.80%29.aspx) is a good example for you.

I think putting them in a ListBox is fairly easy task.

```
RegistryKey keys Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU");

foreach (string subKeyName in keys.GetSubKeyNames())
{
    using(RegistryKey tempKey = keys.OpenSubKey(subKeyName))
            {
                Console.WriteLine("\nThere are {0} values for {1}.", 
                    tempKey.ValueCount.ToString(), tempKey.Name);

                foreach(string valueName in tempKey.GetValueNames())
                {
                    Console.WriteLine("{0,-8}: {1}", valueName, 
                        tempKey.GetValue(valueName).ToString());
                }
            }
}

```
