Where does Windows 7 come from? Evolution History of Microsoft's 7-generation operating system

When the Windows system was bornVery simpleAs in common applications, the first three generations are windows 1.0, Windows 2.0, and Windows 3.0, respectively.CodeThe numbers are the same.

Windows 4.0 was named by the age for the first time, that is, the milestone Windows 95. The following Windows 98, 98 SE, and Millennium (me) are 4.0.1988, 4.10.2222, and 4.90.3000, respectively. Therefore, the Windows 9x series are based on version 4.0 code and belong to the same family.

At the same time, Microsoft has also developed a Windows NT architecture, while Windows 2000, which is newly released in the new century, integrates the outstanding features of desktop Windows 9x and Windows NT architectures, the performance and stability have reached an unprecedented level, and the code version has also been upgraded to 5.0. The naming method of Windows XP was changed again, but the core architecture did not change much. Therefore, the core version number is 5.1.

The latest Windows Vista has made significant changes in the kernel and shell architecture.The code version entered 6.0, which is also caused by a large number of applications in the early stage of release.ProgramThe key cause of incompatibility.

We already know that Windows 7 will still use the main architecture of Windows Vista and will not be re-launched, but will be further improved and upgraded. Therefore, the core version will be 6.1, not 7.0.

Why is it Windows 7?In fact, it has nothing to do with the core code version, just because it is the seventh-generation desktop operating system of Microsoft, it is so simple. When Windows 7.0 comes out, it will be another name.

At the same time, we can also see that although Windows 7 and Windows Vista are very similar to Windows XP in Windows 2000, it is regarded by Microsoft as a two-generation operating system, rather than a unified series. Obviously, the failure of Windows Vista puts a lot of pressure on Microsoft, and the new system has to be pulled away from it. It also proves that Windows 7 has made great progress.

Mike Nash, vice president of Microsoft, said Windows 7 will be an evolutionary (non-revolutionary) major change in the client operating system, microsoft will make new efforts in design, engineering, innovation, and other aspects. The upgrade of the core version from 6.0 to 6.1 ensures that it can continue the excellent features of Windows Vista, on the other hand, the application compatibility can be ensured to the maximum extent, avoiding the trouble during the migration and update process.
