Backup and General Maintenance
• Always backup your important data on a regular basis and keep copies of your operating
system and software safe. Do not forget to note the serial numbers if you are storing
them outside of their original cases ‑ for example, in a CD wallet.
• Run maintenance programs as often as you can. You may schedule these programs to
run at times when you are not using your computer. You can use those provided with your
operating system, or buy more powerful, dedicated programs to do so.
• Write down your passwords and keep them safe (away from your computer). This is
especially important if you choose to password‑protect your computer’s BIOS and
operating system.
• Document vital settings such as network, dialup, mail and Internet settings.
