Internet Explorer 9 on Win 7 64 + KB2964358

Hi, looks like there is a problem with KB2964358 and Internet Explorer 9 on Win 7 64 bits.

When trying to open web sites, IE ask if we want to save the page (default.htm). We are unable to open web site (including http internal application)

I saw this kb : http://support.microsoft.com/kb/2964358

And this thread : http://social.technet.microsoft.com/Forums/ie/en-US/7d41c31d-0f5a-4f79-8275-c76c2e047c3b/after-installation-kb2964358-ie9-wont-work-anymore-and-shows-the-downloadbox-for-every-webpage?forum=ieitprocurrentver

I'm asking myself why Microsoft doesn't revise this update to put KB2936068 as a prerequisite for KB2964358 ?
