Utilities/Config.cs
2010-05-25 Added an event handler to save the configuration when the user logs off without closing the application first (http://blogs.msdn.com/b/oldnewthing/archive/2008/04/21/8413175.aspx), because FormClosed is not called in that case.
2010-02-27 Added support for sensor parameters. Fixed Core and Thread count detection for Intel Core i7 CPUs with disabled HyperThreading.
