Why is it Windows 7: Windows version number?

This is an article by Mike Nash, vice president of Microsoft and in charge of Windows products, posted on the Windows Vista blog.ArticleIt tells the story about the coming version of Windows 7 from the perspective of products and developers.

Since I officially named Windows 7 as the next version of the Windows client operating system, discussions on the naming have continued. Let's talk about the origins of 7. There are many naming methods for Windows. The memories of these names will be very interesting, and we will understand how 7 came from various angles.

In any case, the numbers we use are very simple. The first version of Windows is Windows 1.0, the second version is Windows 2.0, and the third version is Windows 3.0.

It's a bit complicated from 3.0. After Windows 3.0 is Windows NT, itsCodeThe version number is Windows 3.1. Next
Windows 95. The code version is Windows 4.0. And then Windows 98, 98 SE, and Windows
Me, whose versions are 4.01998, 4.10.2222, and 4.90.3000 in sequence. So we call all Windows 9.x
Winodws 4.0.

The code version of Windows 2000 is 5.0. When we launched Windows XP, we used 5.1. Although XP is a major upgrade, we tried to keep the application as much as possible.ProgramThe major version number is not changed.

Later, we had Windows Vista, or Windows 6.0. Therefore, as another major upgrade, the next version of Windows is Windows 7.

When Windows 5.1 is used as the XP version number, we want to help developers maintain API compatibility. When Windows Vista version is changed to 6.0, we have learned a lot, A major compatibility problem occurs when the basic version number is changed.

Therefore, we decided to set Windows 7 as Windows 6.1. You will see the version number in the cms.exe file of Windows 7.

Some people think that setting the version number of Windows 7 to 6.1 means that Windows 7 is a small upgrade. Windows 7 is a major revolutionary innovation, and the only reason we use 6.1 is the need to maintain application compatibility.

In another week, Windows 7 will be displayed on PDC and winhec, and you will receive more information about Windows 7.
