Just in case you need a bunch of unique GUIDs for some reason (some people do, apparently), here is a free GUID Generator for you to use.

You will need .NET platform version 4 installed for it to work (it may or may not be already installed on your machine).

The source code is pretty simple; if you download Visual C# Express (free), all you need to do is put a text box on a form, double-click the form and add the following code in the resulting form load event:

private void Form1_Load(object sender, EventArgs e)
{
	for (int i = 0; i < 10; i++)
	{
		Guid guid = Guid.NewGuid();
		string text = guid.ToString();
		textBox1.AppendText(text);
		textBox1.AppendText("\n");
	}
}

The application just pops up a box with ten GUIDs in it, all unique of course. That's all it does. Have fun!
