Windows 8 is Windows 6.2

Windows Vista kernel version is Windows 6.0, Windows 7 is Windows 6.1, Microsoft has recently confirmed that Windows 8 is Windows 6.2, although this news is already well known.

Presumably, Microsoft has been suffering from a painful lesson in Vista, so that it will not be able to heal for a long time to come. If Windows 8 next-generation kernel version number is Windows 6.3, you don't have to be too surprised.

The biggest problem with the update of the Windows kernel version is the incompatibility with existing applications. On Windows 8, Microsoft is also trying to reduce the potential impact of this problem.

Microsoft has promised that Vista applications will run on Windows 7, and Windows 7 applications will work fine on Windows 8.

Microsoft said: "The kernel version number of Windows Developer Preview and Windows Server Developer Preview is 6.2, and all versions of APIs will return to this version number. ”

This is an important piece of information for application developers, and you only need to make minor adjustments to your development project to ensure that users do not make mistakes when running these applications on Windows 8. “In general, the application does not need to detect the system version number. ” At a minimum, the application should be adapted to a system version that is higher than or equal to the minimum supported, unless there are special circumstances. ”
