Download and Deploy the Internet Explorer 10 Blocker Toolkit Today
The release of Internet Explorer 10 (IE10) brings faster performance and improved web standards support, but automatic upgrades are not always ideal for corporate environments. IT administrators often need time to test line-of-business applications for compatibility before deploying a new browser. To prevent Windows Update from automatically installing IE10 on user machines, Microsoft provides the Internet Explorer 10 Blocker Toolkit.
Deploying this toolkit today ensures your organization maintains control over its desktop environment while you prepare for a phased rollout. What is the Internet Explorer 10 Blocker Toolkit?
The Blocker Toolkit is a free utility from Microsoft designed for enterprise environments. It prevents Windows Update from automatically delivering IE10 as an important update to users running Windows 7 or Windows Server 2008 R2. Key details to keep in mind:
No Expiration: The block remains in effect indefinitely unless you choose to remove it.
No Manual Interference: It does not block users from manually downloading and installing IE10 from the Microsoft Download Center.
No Impact on Other Updates: It will not interfere with the delivery of other critical security updates or patches. How the Blocker Toolkit Works
The toolkit functions by modifying a specific registry key on the local machine. When Windows Update scans the system, it detects this key and hides IE10 from the list of available automatic updates.
The toolkit contains two main components to help you deploy this registry change efficiently:
A Microsoft Excel Template (.adm): Used by Group Policy administrators to manage settings across an entire domain.
A Command-Line Script (.cmd): Used by administrators to run locally or distribute via deployment tools. Step-by-Step Deployment Options
Option 1: Deploying via Group Policy (Recommended for Domains)
For centralized management, using Group Policy Objects (GPO) is the most efficient method to block the update across your network.
Download the Internet Explorer 10 Blocker Toolkit from the Microsoft Download Center.
Extract the contents to a temporary folder on your domain controller. Open the Group Policy Management Console (gpmc.msc).
Create or Edit a GPO that targets the computers you want to manage.
Navigate to Computer Configuration > Policies > Administrative Templates.
Right-click Administrative Templates and select Add/Remove Templates.
Browse to the extracted folder, select IE10_Blocker.adm, and click Add.
Go to Classic Administrative Templates (ADM) > Windows Components > Windows Update > Automatic Updates Blockers v3.
Double-click Do not allow delivery of Internet Explorer 10 through Automatic Updates. Select Enabled, then click Apply and OK.
Option 2: Deploying via the Command-Line Script (For Local or Scripted Execution)
If you use a third-party deployment tool like Microsoft Endpoint Configuration Manager (SCCM), or if you need to configure a single machine, use the included script.
The script uses the following syntax:IE10_Blocker.cmd [computername] [/B] [/U] [/H]
/B (Block): Sets the registry key to prevent IE10 installation.
/U (Unblock): Removes the registry key to allow IE10 installation.
[computername]: Optional. Specifies a remote computer to configure.
To block IE10 on a local machine, open an elevated Command Prompt (Run as Administrator) and run: IE10_Blocker.cmd /B Use code with caution. Preparing for the Future
The Blocker Toolkit is a temporary strategy to buy your IT department time. To ensure your organization benefits from modern security enhancements and performance upgrades, you should use this period to actively test your internal web applications and websites against IE10. Once compatibility is verified, you can easily reverse the registry setting using the same toolkit to initiate your deployment.
If you need assistance with deployment automation, let me know:
What deployment tool do you currently use? (e.g., SCCM, Active Directory GPO, or manual scripts) How many endpoints do you need to manage? What operating systems are dominant in your network?
I can provide customized scripts or step-by-step guidance tailored to your environment.
