# What is the Internet Explorer 11 Blocker Toolkit?


**Last updated**

-   November 12, 2015

**Applies to:**

-   Windows 10
-   Windows 8.1
-   Windows 7
-   Windows Server 2012 R2
-   Windows Server 2008 R2 with Service Pack 1 (SP1)

The Internet Explorer 11 Blocker Toolkit lets you turn off the automatic delivery of IE11 through the **Automatic Updates** feature of Windows Update.

**Important**  
The IE11 Blocker Toolkit doesn't stop users from manually installing IE11 from the [Microsoft Download Center](http://go.microsoft.com/fwlink/p/?linkid=327753). Also, even if you've installed previous versions of the toolkit before, like for Internet Explorer 10, you still need to install this version to prevent the installation of IE11.
