But beware, depending on the age of the most recent restore point, this
may do nothing, or may go back too far. Use this option only if you don??™t
have a more recent backup (discussed next). See ???Go Back in Time with
Restore Points and Shadow Copies,??? later in this chapter, for details.

Troubleshooting
Windows Complete PC Restore
Use this option to wipe your hard disk clean and restore a backup you
made with the Backup and Restore Center that comes with the Business
and Ultimate editions of Windows Vista. (Sorry, Home Basic and Home
Premium users??”apparently your data is not that valuable.) See
???Recover Your System After a Crash,??? later in this chapter.
The fact that the Windows Complete PC Restore feature
wipes your hard disk clean is a strong case for having your
personal data on a separate partition from Windows, as
explained in ???Work with Partitions??? in Chapter 5.
Windows Memory Diagnostic Tool
This examines your PC??™s system memory (RAM) for errors; see ???Test for
Bad Memory (RAM),??? later in this chapter. Unlike the other tools here,
this one makes no changes to your hard disk, so it??™s safe to use at any time.
Command Prompt
Use this tool to open a Command Prompt window, from which you can
copy, delete, or rename files that may be preventing Windows from loading.
Also available is the Safe Mode with Command Prompt, discussed
later in this section. See Chapter 9 for details on the Command Prompt,
including an overview of the commands you can type at the prompt.
