Microsoft Silverlight is a component in many web browsers that helps them stream and display video, music, clickable menus, and other types of 'rich media' content. Launched in 2007, it was intended as a replacement for Adobe Flash, which was the de facto plugin for playing media online at the time.

Silverlight has a troubled history, though, and has been largely abandoned by Microsoft, third-party developers, and users since about 2015. If you've heard of Silverlight, it's probably from Netflix nagging you to install it a few years ago.

Microsoft will completely retire the remaining Silverlight elements in October 2021. But before then, here's what you should know about Silverlight

What is Microsoft Silverlight?

Ms Silverlight

As stated, Silverlight is a browser plugin that was meant to help users stream videos and use websites more easily. Its software development kit (SDK) and other resources are still available to download for free.

Silverlight started strong - NBC even used the platform to stream the 2008 Summer Olympics in Beijing - and the plugin was available for most major browsers for several years. Silverlight directly supported most video and animation formats like H.264, MP3, MP4, and WMV files without forcing the user to download additional software.

Silverlight ran in the background in most browsers, although notably many Mac users in the early-to-mid 2010s faced issues running Netflix because of it.

The platform soon became redundant, however, with the release of HTML5. HTML5 is a rich media platform integrated into all modern web browsers that eliminates the need to install a plug-in like Silverlight (or Adobe Flash, for that matter).

Major online partners quickly moved from Silverlight to HTML5 - Netflix and Amazon Prime Video both made the transition in 2015, for example. Google Chrome dropped support for Silverlight in 2015 and Firefox abandoned the platform in 2017. Macs haven't supported Silverlight since 2016. Even most versions of Microsoft's Internet Explorer stopped using Silverlight at the start of 2020.

Currently, the only major browser that continues to support Silverlight is Internet Explorer 11 for Windows 10. And even it will discontinue it by the end of 2021.

The end of Silverlight

Microsoft hasn't actively developed Silverlight since about 2015, and the platform will be completely retired on October 12, 2021. At that time, Microsoft will stop providing updates for the platform, and will remove access to the installer as well as the SDK and other resources.

However, since Silverlight has a 'perpetual license,' existing Silverlight applications won't be shut down. It just means that they won't be updated, and it may be harder to find a browser that can run them.

For security reasons new builds of Microsoft Office for Microsoft 365 on Windows block activation of Flash, Silverlight, and Shockwave controls. Most users won't be impacted, but for some users this may cause one of the following issues:

Caution: Follow these steps carefully. Serious problems may occur if you modify the registry incorrectly. Before you start we recommend that you have a known good backup of your registry. See this article for more information: How to back up and restore the registry in Windows.

  1. Exit all Microsoft Office applications Mac os x snow leopard dvd iso.

  2. Start the Registry Editor by tapping Start (or pressing the Windows key on your keyboard) then typing regedit and pressing enter.

  3. Locate the proper registry subkey. It will be one of the following:

    Samsung android pc suite for windows 10. HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0CommonCOM Compatibility
    (for 64-bit Office, or 32-bit Office on 32-bit Windows)

    or

    HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftOffice16.0CommonCOM Compatibility
    (for 32-bit Office on 64-bit Windows)

    Note: The COM Compatibility node may not be present by default. If you don't see it, add it by right-clicking the Common node and choosing Add Key.

  4. Add a new subkey with the CLSID of the control you want to unblock as the value by right-clicking the COM Compatibility node and choosing Add Key.

    CLSID

    Flash

    {D27CDB6E-AE6D-11CF-96B8-444553540000}

    {D27CDB70-AE6D-11CF-96B8-444553540000}

    Silverlight

    {DFEAF541-F3E1-4c24-ACAC-99C30715084A}

    Shockwave

    {233C1507-6A77-46A4-9443-F871F945D258}

    Note: For Flash you'll need to add two subkeys, one for each of its CLSID's.

  5. Within that new subkey we're going to add two new values by right-clicking the new subkey and choosing New > DWORD (32-bit) Value. Shareit terbaru untuk pc.

    • A REG_DWORD hexadecimal value called Compatibility Flags with a value of 0.

    • A REG_DWORD hexadecimal value called ActivationFilterOverride with a value of 1.

  6. Exit Registry Editor and start your application. The control you need should be unblocked now.

Example

For example, to unblock Silverlight in order to get Power View working in Office 2016, 64-bit, on Windows you would locate this registry key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0CommonCOM Compatibility

Note: Remember, if the COM Compatibility node doesn't exist yet you'll need to create it.

Then add a subkey with the value {DFEAF541-F3E1-4c24-ACAC-99C30715084A}.

In this case, the resulting path is HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice16.0CommonCOM Compatibility{DFEAF541-F3E1-4c24-ACAC-99C30715084A}.

To that subkey you'll add a REG_DWORD value called Compatibility Flags with a value of 0, and a REG_DWORD value called ActivationFilterOverride with a value of 1.
