The signature information is presented to the user to help inform them of the file. This information will be shown to the user before opening the file. The publisher information is shown before opening a file type that is signable and that can potentially harm the user. The Authenticode dialog box presents this information to the user, who can then make a more informed decision about running the file. Why is this change important? This change helps bring consistency and clarity to the experience of downloading files and code to a user. The publisher check provides crucial information when a signature is found in a file and provides a systematic way to prevent files that are from suspicious publishers from compromising the security of a computer. What works differently? Files with blocked publishers are not allowed to run. How do I resolve these issues? You can unblock a publisher of an add- on by using Manage Add- ons in Internet Explorer. To unblock a publisher to enable the download of a specific file, you can remove the publisher from the Untrusted Publishers list. To do this, in Internet Explorer, on the Tools menu, click Options, click the Content tab, and then remove the publisher. WeDownload Manager is a.

It provides a warning about the risk associated with installing the add- on in order to help the user make a good decision about installing the add- on. Also, additional functionality was added to the prompt so that users always block a publisher, indicating that Windows. This blocks the publisher from running code on the computer. Why is this change important? This change helps bring consistency and clarity to the experience of downloading files and code to a user. In addition, the user can choose not to trust a publisher when the user is prompted to install the add- on. This gives users more control over their experience. What works differently? Are there any dependencies? When you install an add- on, the user interface is more clear and concise. How do I resolve these issues? By default, Internet Explorer will not allow users to run invalid or unsigned Active. X controls. The Information Bar will provide an alternative way for the user to choose to install a blocked control. For more information about the Internet Explorer Information Bar, see the information later in this document. What settings are added or changed in Windows. It also shows the presence of some add- ons that were previously not shown and could be very difficult to detect. Internet Explorer Add- on Crash Detection attempts to detect crashes in Internet Explorer that are related to an add- on. When the add- on is successfully identified, this information is presented to the user. The user has the option of disabling add- ons to diagnose crashes and improve the overall stability of Internet Explorer. Who does this feature apply to? Users will be able to view, enable, and disable the add- ons used by Internet Explorer, and identify add- ons that might be related to Internet Explorer crashes. Administrators can enforce a list of add- ons that are allowed or disallowed and restrict the ability of users to manage add- ons. What new functionality is added to this feature in Windows. It also shows the presence of some add- ons that were previously not shown and could be very difficult to detect. These add- ons might provide undesired functionality or services and, in some cases, might present a security risk. For example, a user might unintentionally install an add- on that secretly records all Web page activity and reports it to a central server. Previously, specialized software and deep technical knowledge might have been required to identify and remove that add- on. Internet Explorer Add- on Management provides an easier way to detect and disable that add- on. Add- ons include: Browser help objects. Active. X controls. Toolbar extensions. Browser extensions. Add- ons can be installed from a variety of locations and in several ways, including: Download and installation while viewing Web pages. Installation by the user by way of an executable program. As pre- installed components of the operating system. As pre- installed add- ons that come with the operating system. Manage Add- ons. Users can enable and disable each add- on individually and view information about how often the add- ons have been used by Internet Explorer. To do this, use the following procedure to open Manage Add- ons. Click Start, and then click Internet Explorer. Click Tools, and then click Manage Add- ons. You can also open Manage Add- ons through Control Panel by following these steps: Click Start, and then click Control Panel. Double- click Internet Options. Click the Programs tab, and then click Manage Add- ons. Manage Add- ons has several options that allow you to change your add- on configuration. You can use Show to control the way in which the add- ons list is displayed. It has two options: Add- ons currently loaded in Internet Explorer. This option lists the add- ons that have been instantiated (or loaded into memory) within the current Internet Explorer process and those which have been blocked from instantiating. This includes Active. X controls that were used by Web pages that were previously viewed within the current process. Add- ons that have been used by Internet Explorer. This option lists all add- ons that have been referenced by Internet Explorer and are still installed. The list of add- ons shows all installed add- ons of the types mentioned earlier in this document. To enable or disable an installed add- on, click the add- on in the list, then click Enable or Disable. If you click an Active. X control in the list, then click Update Active. X, Windows searches for an update at the location where the original control was found. If a newer version is found at that location, Internet Explorer attempts to install the update. The list of add- ons also contains signed add- ons that were blocked from installation because their publisher was untrusted. After selecting one of these controls, the user can unblock the control by clicking Allow. Caution should be exercised when doing this, because clicking Allow removes the publisher from the Untrusted list. Blocked Add- on status bar icon. A Blocked Add- on icon appears in the status bar when a Web page attempts to instantiate an Active. X control that is disabled or blocked because its publisher is untrusted. You can double click the icon to open Manage Add- ons. The status bar icon is accompanied by a balloon tip the first five times it appears. Add- on notification balloon tip. When a Web page attempts to instantiate a disabled add- on and there is no current Blocked Add- on status bar icon, a message appears to tell the user that the current Web page is requesting an add- on that is disabled. The user can click the message for more details on blocking add- ons. You can use Control Panel to suppress the message. This option is described later in this document. Why is this change important? What threats does it help mitigate? Windows Error Reporting data has shown that add- ons are a major cause of stability issues in Internet Explorer. These add- ons significantly affect the reliability of Internet Explorer. These add- ons can also pose a security risk, because they might contain malicious and unknown code. Many users are unaware of the add- ons they have installed on their computer. Some add- ons are loaded whenever Internet Explorer is started, but cannot be detected unless the user searches the registry. When users experienced crashes, there was no easy way to diagnose whether the issue was related to an add- on. Even if they suspected that the problem stemmed from recently- installed software, it was difficult to isolate the cause and often impossible to resolve if the software did not provide an uninstall option. Internet Explorer Add- on Management, together with Add- on Crash Detection, gives users the ability to improve the security and stability of their systems by identifying and disabling problematic add- ons. Administrators are also provided with a powerful administrative tool to control add- on use in their organization. What works differently? Behavior when add- ons are disabled. Disabling an add- on does not remove it from the computer. It only prevents Internet Explorer from instantiating the object and executing its code. There is no guarantee that the disabled add- on will never be loaded, since an add- on that is considered by Internet Explorer to be disabled can still be used by another component in the system. The behavior that is displayed by disabling different object types varies.
