# What is the Internet Explorer 11 Blocker Toolkit?
**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](https://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.
 **To install the toolkit**
1. Download the IE11 Blocker Toolkit from [Toolkit to Disable Automatic Delivery of Internet Explorer 11](https://go.microsoft.com/fwlink/p/?LinkId=327745).
2. Accept the license agreement and store the included 4 files on your local computer.
3. Start an elevated Command Prompt by going to **Start**>**All Programs**>**Accessories**> right-clicking on **Command Prompt**, and then choosing **Run as Administrator**.
4. In the Command Prompt, change to the location where you put the 4 files.
5. In the Command Prompt, type `ie11_blocker.cmd /B` and press Enter.
Wait for the message, **Blocking deployment of IE11 on the local machine. The operation completed successfully.**
6. Close the Command Prompt.
