Hi,

Take a look at using the Microsoft.Win32.Registry class to change the value
of the HKEY_LOCAL_MACHINE\Ident\Name string value.

For example:

using Microsoft.Win32;

using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Ident", true))
{
 key.SetValue("Name", "my_new_device_name");
 key.Close();
}

You can verify that the change was picked up by the OS by executing
something like the following:

MessageBox.Show(System.Net.Dns.GetHostName(), "Current Device Name");

Hope this helps,
