If you are using IE in your system then it will be automatically pushed to IE8 through Windows Automatic Updates. This process will begin by third week of this month. This is expected to happen in Windows XP, Windows Vista, Windows 2003 Server and Windows 2008 server. Therefore, Microsoft will prompt you to install the browser. If you don’t like this intimation you can completely block these types of intimations using a toolkit which officially comes from Microsoft.
It will disable the automatic delivery of Internet Explorer 8. Moreover, this tool will disable automatic update of Internet Explorer 8 as high-priority update through Automatic Updates and the Windows and Microsoft Updates sites.
