Microsoft Keyboard Layout Creator can load system keyboards and export them as .klc files. Since it’s written in .NET you can use Reflector to see how it does that, and use reflection to drive it. Here's a zip file of .klc files for the 187 keyboards in Windows 8 created using the below C# code. Note that I originally wrote this for Windows XP, and now with Windows 8 and the on-screen keyboard, it is really slow and seems to crash the taskbar :/ However, it does work :)

class KeyboardExtractor {
static Object InvokeNonPublicStaticMethod(Type t, String name,
Object[] args)
{
return t.GetMethod(name, BindingFlags.Static | BindingFlags.NonPublic)
.Invoke(null, args);
}
static void InvokeNonPublicInstanceMethod(Object o, String name,
Object[] args)
{
o.GetType().GetMethod(name, BindingFlags.Instance |
BindingFlags.NonPublic) .Invoke(o, args);
}

return o.GetType().GetField(propertyName,
BindingFlags.Instance | BindingFlags.NonPublic)
.GetValue(o);
}

DateTime loopStartTime = DateTime.UtcNow;
int i = 0;
foreach (DictionaryEntry e in keyboards) {
i += 1;
Object k = e.Value;
String name = (String)GetNonPublicProperty(k, "m_stLayoutName");
String layoutHexString = ((UInt32)GetNonPublicProperty(k, "m_hkl"))
.ToString("X");
TimeSpan elapsed = DateTime.UtcNow - loopStartTime;
Double ticksRemaining = ((Double)elapsed.Ticks * keyboards.Count)
/ i - elapsed.Ticks;
TimeSpan remaining = new TimeSpan((Int64)ticksRemaining);
String msgTimeRemaining = "";
if (i > 1) {
// Trim milliseconds
remaining = new TimeSpan(remaining.Hours, remaining.Minutes,
remaining.Seconds);
msgTimeRemaining = String.Format(", about {0} remaining",
remaining);
}
System.Console.WriteLine(
"Saving {0} {1}, keyboard {2} of {3}{4}",
layoutHexString, name, i, keyboards.Count,
msgTimeRemaining);
SaveKeyboard(name, layoutHexString);
}
System.Console.WriteLine("{0} elapsed", DateTime.UtcNow - startTime);
}
private void SaveKeyboard(String name, String layoutHexString) {
Object k = keyboardType.GetConstructors(
BindingFlags.Instance | BindingFlags.NonPublic)[0]
.Invoke(new Object[] {
new String[] {"", layoutHexString},
false});
SetNonPublicField(k, "m_fSeenOrHeardAboutPropertiesDialog", true);
SetNonPublicField(k, "m_stKeyboardTextFileName",
String.Format("{0}\\{1} {2}.klc",
baseDirectory, layoutHexString, name));
InvokeNonPublicInstanceMethod(k, "mnuFileSave_Click",
new Object[] {new Object(), new EventArgs()});
((IDisposable)k).Dispose();
}
}
Basically, it gets a list of all the keyboards on the system, then for each one, loads it in MSKLC, sets the "Save As" filename, lies about whether it's already configured the custom keyboard properties, and then simulates a click on the File -> Save menu item.
