Microsoft Silverlight Configuration Dialog Box

Microsoft Silverlight will reach end of support after October 2021. Learn more.

To configure the Silverlight plug-in, a user can right-click it and then select Silverlight. This opens the Microsoft Silverlight Configuration dialog box as shown in the following illustration.

Users can also access this dialog box from the Microsoft Silverlight folder on the Start menu or through a configuration application. On Windows, this application is found in one of the following locations:

  • On 32-bit operating systems: C:\Program Files\Microsoft Silverlight\versionNumber\Silverlight.Configuration.exe

  • On 64-bit operating systems: C:\Program Files (x86)\Microsoft Silverlight\versionNumber\Silverlight.Configuration.exe

On Macintosh computers, users can access the configuration application by following these steps:

  1. In Finder, navigate to /Library/Internet Plug-Ins.

  2. Right-click (or press CTRL and then click) Silverlight.plugin and then select Show package contents.

  3. Navigate to Contents/Resources and then double-click

This topic describes the configuration options available to end users. It also provides the same links that appear in the dialog box, plus links to relevant developer topics.


Because the Silverlight plug-in can be updated more frequently than the documentation, the dialog box might be slightly different than what this topic describes.

About Tab

The About tab provides the Silverlight plug-in version information, copyright data, and the links to the following documents:

Updates Tab

The Updates tab enables users to specify when to check for, download, and install Silverlight updates. The following options are available:

  • Install updates automatically (recommended).

  • Check for updates, but let me choose whether to download and install them.

  • Never check for updates.

The Updates tab also provides the following links:

Playback Tab

The Playback tab allows users to enable or disable playback of content protected by digital rights management (DRM). For end-user documentation, see the Silverlight Privacy Statement. For developer documentation, see Digital Rights Management (DRM).

Webcam / Mic Tab

The Webcam / Mic tab allows users to choose Silverlight's default audio and video capture devices. For developer documentation, see Audio and Video.

Permissions Tab

The Permissions tab allows users to change the permissions that they have established through user-consent dialog boxes. These dialog boxes appear when an application attempts to use the StaysFullScreenWhenUnfocused setting of the Content.FullScreenOptions property and the Clipboard, AudioSink, and VideoSink classes.


Trusted applications do not require user consent except when accessing the AudioSink (microphone) and VideoSink (camera) functionality. For developer documentation, see Trusted Applications.

Application Storage Tab

The Application Storage tab enables users to see a list of the Web sites that are using application storage space on the user's computer. For each Web site, the current usage and the maximum quota are indicated, in megabytes.

Users can use the Application Storage tab to enable or disable application storage, and to delete the storage space used by one or more Web sites.

For end-user documentation, see Using Application Storage. For developer documentation, see Isolated Storage.
