However, it is generally difficult or even impossible to contact each member of the population.. The author explores the main features of Windows XP from managing files, exploring folders, through to the control panel, printers and home networking. It is therefore an ideal introductory guide for those new to the Windows environment and enables readers to gain confidence when using the system. Tailored for non-US users Requires no technical or in-depth computer knowledgeFrequent screen shots enable readers to understand Windows XP and make use of its full capabilities Alok Majumdar, Andre Leclair, Ric Moore.
