If the user turns on “Enhanced Protected Mode” in Internet Options, Advanced they will have 64-bit tabs by default for IE 10 on the Desktop. However, for compatibility with plug-ins, IE 10 on the desktop runs 32-bit tabs by default. On 64-bit Windows 8, the browser frame process (both “modern UI” and Desktop) runs 64-bit. We reached out to Microsoft for clarification and received this response from the company's Internet Explorer spokesperson: However, a recent report on the website claimed that Microsoft would not allow the desktop version of IE 10 to run in 64-bit builds of Windows 8 and that only the "Modern" UI version of IE 10 could run with the 64-bit version. Microsoft will also allow Internet Explorer 10 to run in both user interfaces. Both versions will also come with the "Modern" (previously Metro) user interface as well as the more traditional desktop UI. When Windows 8 is launched to the general public on October 26th, Microsoft will offer both 32-bit and 64-bit versions of the OS. This post is intended to clear up some confusion we have seen on the web as well as in our forums/tip box.
