Update (2017):<\/strong> See .NET Framework Releases<\/strong><\/a> to learn about newer releases. This release is unsupported.<\/p>\n

We are happy to announce that the\u00a0.NET Framework 4.5.1<\/a> and its language packs are now available via Windows Update (WU) and WSUS. You can learn more about the release from the What’s new in the .NET Framework 4.5.1<\/a> topic.<\/span><\/p>\n

This update is available in the Windows Update<\/strong> applet within the Control Panel<\/strong>. You may need to use the Check for updates<\/strong> feature from within the Windows Update<\/strong> applet to get the release to show up.\n<\/span><\/p>\n

Automatic Updates<\/span><\/h2>\n

The .NET Framework 4.5.1 release is being made available as a Recommended Update<\/strong>, this means that users with Automatic Updates configured to install automatically will get the release automatically. This is the default experience. Users that have modified their AU settings to notify them when updates are available or downloaded will see a notification in their system tray about this update.<\/span><\/p>\n

We have throttled the distribution of the release via Automatic Updates, which means that a subset of users will be updated each day instead of all users getting the update on the first day. This is done so we can receive and react to customer feedback regarding this update. So if you don\u2019t get the update offered on the first day and do not want to wait until the update is offered you can use the Check for updates<\/strong> feature, which is not throttled, as described above.<\/span><\/p>\n

Windows Server Update Services (WSUS) and Catalog<\/span><\/h2>\n

WSUS administrators should see this update in their WSUS admin console. The update is also available in the MU catalog for download and deployment.\n<\/span><\/p>\n

Blocking the automatic deployment of .NET Framework 4.5.1<\/span><\/h2>\n

In some cases enterprises may have client machines that connect directly to the public Windows Update servers rather than to an internal WSUS server. In such cases, an administrator may have a need to prevent the .NET Framework 4.5.1 from being deployed to these client machines, for example in order to allow testing of internal\/LOB apps to complete.<\/span><\/p>\n

Admins can deploy a registry key to machines in order to prevent the .NET Framework 4.5.1 from being offered to those machines. More information about how to use this blocker registry key can be found in the following Microsoft Knowledge Base article:<\/span><\/p>\n
