This setting controls whether users can participate in the Microsoft Customer Experience Improvement Program to help improve Microsoft applications. When users choose to participate in the Customer Experience Improvement Program (CEIP), applications automatically send information to Microsoft about how the applications are used. This information is combined with other CEIP data to help Microsoft solve problems and to improve the products and features customers use most often. This feature does not collect users' names, addresses, or any other identifying information except the IP address that is used to send the data. By default, users have the opportunity to opt into participation in the CEIP the first time they run an application. If your organization has policies that govern the use of external resources such as the CEIP, allowing users to opt in to the program might cause them to violate these policies.

Internet Explorer uses Multipurpose Internet Mail Extensions (MIME) data to determine file handling procedures for files received through a Web server. The Consistent MIME Handling\Internet Explorer Processes policy setting determines whether Internet Explorer requires that all file-type information provided by Web servers be consistent. For example, if the MIME type of a file is text/plain but the MIME data indicates that the file is really an executable file, Internet Explorer changes its extension to reflect this executable status. This capability helps ensure that executable code cannot masquerade as other types of data that may be trusted. If you enable this policy setting, Internet Explorer examines all received files and enforces consistent MIME data for them. If you disable or do not configure this policy setting, Internet Explorer does not require consistent MIME data for all received files and will use the MIME data provided by the file. MIME file-type spoofing is a potential threat to your organization. Ensuring that these files are consistent and properly labeled helps prevent malicious file downloads from infecting your network. This guide recommends you configure this policy as Enabled for all environments specified in this guide.System AdministratorInformation Assurance OfficerECSC-1

MIME sniffing is the process of examining the content of a MIME file to determine its context — whether it is a data file, an executable file, or some other type of file. This policy setting determines whether Internet Explorer MIME sniffing will prevent promotion of a file of one type to a more dangerous file type. When set to Enabled, MIME sniffing will never promote a file of one type to a more dangerous file type. Disabling MIME sniffing configures Internet Explorer processes to allow a MIME sniff that promotes a file of one type to a more dangerous file type. For example, promoting a text file to an executable file is a dangerous promotion because any code in the supposed text file would be executed. MIME file-type spoofing is a potential threat to your organization. Ensuring that these files are consistently handled helps prevent malicious file downloads from infecting your network. This guide recommends you configure this policy as Enabled for all environments specified in this guide.

Setting this policy to Enabled blocks the MK protocol for Windows Explorer and Internet Explorer, which causes resources that use the MK protocol to fail. Disabling this setting allows applications to use the MK protocol API. Because the MK protocol is not widely used, it should be blocked wherever it is not needed. This guide recommends you configure this setting to Enabled to block the MK protocol unless it is specifically needed in your environment. Note: Because resources that use the MK protocol will fail when you deploy this setting, you should ensure that none of your applications use the MK protocol.System AdministratorECSC-1

Internet Explorer places restrictions on each Web page it opens that are dependent upon the location of the Web page (such as Internet Zone, Intranet Zone, or Local Machine Zone). Web pages on a local computer have the fewest security restrictions and reside in the Local Machine Zone, which makes the Local Machine Security Zone a prime target for malicious attackers. If you enable this policy setting, any zone can be protected from zone elevation by Internet Explorer processes. This approach stops content running in one zone from gaining the elevated privileges of another zone. If you disable this policy setting, no zone receives such protection for Internet Explorer processes.

Internet Explorer uses Multipurpose Internet Mail Extensions (MIME) data to determine file handling procedures for files received through a Web server. The Consistent MIME Handling\Internet Explorer Processes policy setting determines whether Internet Explorer requires that all file-type information provided by Web servers be consistent. For example, if the MIME type of a file is text/plain but the MIME data indicates that the file is really an executable file, Internet Explorer changes its extension to reflect this executable status. This capability helps ensure that executable code cannot masquerade as other types of data that may be trusted. If you enable this policy setting, Internet Explorer examines all received files and enforces consistent MIME data for them. If you disable or do not configure this policy setting, Internet Explorer does not require consistent MIME data for all received files and will use the MIME data provided by the file.

Internet Explorer allows scripts to programmatically open, resize, and reposition various types of windows. Often, disreputable Web sites will resize windows to either hide other windows or force you to interact with a window that contains malicious code. The Scripted Window Security Restrictions security feature restricts pop-up windows and prohibits scripts from displaying windows in which the title and status bars are not visible to the user or hide other windows’ title and status bars. If you enable the Scripted Window Security Restrictions\Internet Explorer Processes policy setting, pop-up windows and other restrictions apply for Windows Explorer and Internet Explorer processes. If you disable or do not configure this policy setting, scripts can continue to create pop-up windows and windows that hide other windows. This guide recommends you configure this setting to Enabled to help prevent malicious Web sites from controlling your Internet Explorer windows or fooling users into clicking on the wrong window.System AdministratorECSC-1

MIME sniffing is the process of examining the content of a MIME file to determine its context — whether it is a data file, an executable file, or some other type of file. This policy setting determines whether Internet Explorer MIME sniffing will prevent promotion of a file of one type to a more dangerous file type. When set to Enabled, MIME sniffing will never promote a file of one type to a more dangerous file type. Disabling MIME sniffing configures Internet Explorer processes to allow a MIME sniff that promotes a file of one type to a more dangerous file type. For example, promoting a text file to an executable file is a dangerous promotion because any code in the supposed text file would be executed. MIME file-type spoofing is a potential threat to your organization. Ensuring that these files are consistently handled helps prevent malicious file downloads from infecting your network. This guide recommends you configure this policy as Enabled for all environments specified in this guide.
