+Routine Description:
+
+    This function creates the Win32 object type descriptors at system
+    initialization and stores the address of the object type descriptor
+    in local static storage.
+
+Arguments:
+
+    None.
+
+Return Value:
+
+    A value of TRUE is returned if the Win32 object type descriptors are
+    successfully created. Otherwise a value of FALSE is returned.
