Microsoft had just released the first preview build of its next web browser, IE10.The important thing about this browser is that it will be released for Windows 7 and Windows 8
We are expecting that Microsoft will release this IE10 with Windows 8.
The thing we noticed in this release is that IE10 will not support Windows XP as IE9 also don’t support it but this time Windows Vista is also out of the list.
If you visit Microsoft’s Test Drive page you will find Minimum requirement for IE10 as :-
The Internet Explorer Platform Preview requires Windows 7 (x86 or x64) Operating System. Platform Preview 4 and later require updates to be installed on Windows 7 systems
So its our advice if you are still using Widows XP or Windows Vista then you should upgrade yourself to Windows 7 as Microsoft is ending supports for them.
