Microsoft has recently proclaimed that Windows XP is unable to support the recent Internet Explorer 9 browser due to the security restrictions in XP which will disable the operating system's functions in the new browser.

The company announced the failure of XP in providing support this week, while releasing the first preview of IE9.

Microsoft had planned to end XP's support system by the end of 2011, but it extended the plan for further 3 years in view of the strong consumer market of the operating system and also because it has not yet, been able to find a suitable buyer of its Vista version.

The Internet Explorer 9 will have the necessary support system for running the new HTML 5 standards. It will also provide a better Java engine.

"HTML5 will enable a new class of applications", said Dean Hachamovitch, Microsoft's Internet Explorer General Manager.

Microsoft has been trying to shift of the consumer choice from Windows XP to the latest Windows 7, offering better security functions.

Hachamovitch explained that the upgraded versions of the browser need new support systems as well.
