Which system is better for windows7 and xp?

Recently, major forums and post bars about windows7 and xp which are good topics are very hot, but most friends will choose to say that Windows 7 system is good, in fact, if you consider the computer configuration, Windows 7 is not necessarily easy to use, at present, quite a lot My friend's computer is bought 2 years ago. After installing the Windows 7 system, I feel that the speed is obviously not as good as the previous installation of Windows XP system. So, from a low configuration point of view, Windows 7 is not necessarily better than the Windows XP system.
In addition, from a practical point of view, the windows xp system is still enough for most of our applications, it is still a relatively small disk system, because the windows 7 system is equivalent to the windows xp system beautification and upgrade version, so if you consider Practical, in fact, the difference is also small.
In general, XP is used on current hardware, and there are some advantages in speed. At the same time, due to its long release time, compatibility is higher. But many of the new technologies that Windows 7 gives us are not available in XP. And through optimization, Windows7 has not lost XP in program execution. For compatibility issues, Microsoft also provides a solution for everyone on Windows 7 - XP mode, using virtualization technology, will directly support XP programs to Windows 7. In addition, Windows XP has stopped selling, and will eventually lose Microsoft's technical support in the future, so choose Windows 7, especially those who buy new computers, it is very correct, but for old computers, windows xp system is still good. select.
