| Enhanced Protected Mode
|
| Enhanced Protected Mode is a new feature in Internet Explorer 10. It
works by extending the existing Protected Mode functionality to help
prevent attackers from installing software, accessing personal
information, accessing information from corporate Intranets, and from
modifying system settings. To do this, Enhanced Protected Mode must reduce
some of the capabilities available to Internet Explorer, including:
|
| Restricting access to personal assets. Restricts Internet Explorer
from locations that contain your personal information until you grant
permissions to it. This helps prevent unauthorized access to your personal
information.
|
| Restricting access to corporate assets. Restricts access to valuable
information on your corporate network resources by controlling access
through the following tab processes:
|
| Not allowing Internet tab processes to have access to a user's
domain credentials.
|
| Not allowing Internet tab processes to operate as local web
servers.
|
| Not allowing Internet tab processes to make connections to
intranet servers.
|
| Administrators can also use the Group Policy setting, Turn on Enhanced
Protected Mode, to control how Enhance Protected Mode is used in their
organization. For more information about Enhanced Protected Mode, see the
Enhanced Protected Mode post on IEBlog, and both the Understanding
Enhanced Protected Mode and the Enhanced Protected Mode and Local Files
blog posts on IEInternals.
I don't think that this has anything to do with enabling 64-bit...
