The book is as simple as possible, but in sufficient detail, it tells about how to communicate with a modern personal computer, how to customize it "for yourself," solve various problems and successfully overcome emerging difficulties. Most of the described techniques are illustrated by practical examples based on well-known, as well as free and freely distributed programs. In the third edition, the author tried to make the most of the standard features of the Windows 7 environment, supplementing them, if necessary, with applications that make working on a PC more convenient and efficient.
