Window Hiding with C#(ZT)

Introduction
Ever wanted to completely hide all the crap on your machine that you're not supposed to be looking at when your boss walks by? Try this handy Window Hider utility and all you will have to do is press a customizable hotkey.    
This source project will demonstrate the implementation of hot keys, enumerable collections, enums, binary serialization, DllImports of Win32 API, Window Enumeration, CallBacks/Delegates, Custom Events and Event Handlers, and more. It's quite a bit of code to look through but some of you may find it interesting.
The guts of the application is based in the Window and Windows classes that enumerate and hide the open windows your choose: using System;using System.Text;using System.Collections;using System.Runtime.InteropServices; namespace WindowHider{    ///

    /// Object used to control a Windows Form.    ///

    public class Window    {        ///
