IE9 only supports Windows 7 and Vista SP2

According to foreign media reports, DeanHachamovitch, department manager of Microsoft IE, said that if the customer deploys WindowsIE9PlatformPreviewIE9 in VistaSP1, XP SP3, or earlier Windows systems ), the following message is displayed during installation: WindowsInternetExplorerPlatformPreview does not support any operating system version earlier than WindowsVistaSP2.

Analysts said that the information published by Microsoft is undoubtedly required to install the system platform of IE9. In fact, the Windows 9 preview and final editions only support Microsoft's latest operating systems.

Of course, the hope for non-Windows IE9 is even more embarrassing. Hacharmovic has said that Microsoft has not yet planned to develop Internet Explorer 9 for Mac and Linux.

IE9 will discard the early Image Rendering Engine GDI Graphics Device Interface in Windows), and then use Direct2D and DirectWriteAPI application programming interfaces to render 2D images and text respectively. Windows7 and the introduction of Direct2D, WindowsVistaSP2 and WindowsServer2008R2 subsequently introduced Direct2D. However, Windows XP does not add a new application programming interface.

For the support of the old operating system, the IE9 development team said in an email:

"Windows XP users have a fast, secure, reliable, and private InternetExplorer8 browser. From security to the future of HTML5 applications, the development of Web will change everything. Today, developers should improve their browser graphics and security architecture. InternetExplorer9 requires advanced graphics and security architecture, so it must run in a new operating system based on the latest hardware and system technology ."

Analysts believe that Microsoft only encourages PC users to upgrade to Wnidows7. However, many loyal XP users may switch to other new browsers, such as Chrome, Opera, and Safari.
