Start With a Backup
All PC tweaking begins with a backup, even if you simply create a new restore point. To set one in XP, click Start, Programs (or All Programs), Accessories, System Tools, System Restore, choose Create a restore point, click Next, and step through the wizard. In Vista, click Start, Programs (or All Programs), Maintenance, Backup and Restore Center, select Create a restore point or change settings, choose System Restore, click Next, and then follow the on-screen instructions.
Restore points won’t solve all your problems. That’s why one of the most welcome new tools in Vista is Complete PC Backup, which creates a snapshot of your machine, including all of your applications, settings, and data files. Later, if (when?) your hardware fails, you can restore the entire system, not just your files. (Note that Complete PC Backup is not available in Vista Home Basic or Home Premium.)
To create a backup, click Start, Control Panel (or Start, Settings, Control Panel on the Classic Start menu), Back up your computer (in Classic View, double-click Backup and Restore Center). Choose Back up computer and follow the steps. I recommend making a backup at least once per month…
