The choice of operating system depends on the needs of the user tasks and computer settings. Before installing, you need to know if the computer settings for the operating system. In order to properly pick up, you need to consider the features of each system separately and compare them.
Windows 7 has better functionality than other OS as compatible with many games and programs. The main advantage of Windows 7 is that the interface of this system is similar to the usual Windows XP user. So after installing don't have to adapt to the new interface and layout settings. It is convenient for those who do not like radical changes and unexpected updates. This is especially true of "start menu", which is mutated in Windows 8.

It can already be noticed when the computer starts, when instead of the usual desktop display different application shortcuts. It is convenient and practical mainly for tablet users. Thus, the developers of Windows 8 replaced the start menu.
