A. Installing Windows XP
If your PC came with Windows XP installed, you may be able to use it for the life of the machine without ever referring to this appendix. But if you're upgrading to XP from Windows 98, Me, 2000, or NT, this appendix will show you how to install your new operating system. Tinkerers and hobbyists will find useful information here too; a clean Windows installation is the last word in restoring the speed of a computer that has grown slow with accumulated software glitches, partially uninstalled programs, and other baggage. Read on to learn the particulars of the Windows Setup program.
