When a tool can be used to expose or demonstrate some aspect of Windows 2000 internal behavior, the steps necessary to try the tool yourself are listed in "Experiment" boxes. These appear throughout the book, and we encourage you to try these as you're reading—seeing visible proof of how Windows 2000 works internally will make much more of an impression on you than just reading about it. Many of the experiments use the kernel debugger. The live kernel debugger tool (LiveKd) included on the book's companion CD makes these experiments easy and safe to try.
