Microsoft periodically updates Internet Explorer 10 and 11 in Windows 7 and 8.1. To prevent the Update service from updating Internet Explorer 11 in Windows 8.1, disable the Install new versions automatically option. To prevent Microsoft from updating Internet Explorer 10 to Internet Explorer 11 in Windows 7, run the Internet Explorer 11 Blocker Toolkit from Microsoft. If you use Internet Explorer, you could be vulnerable to exploits by not updating.
Launch Internet Explorer 11 in Windows 8.1. Press Windows-S to display the Search charm, type Internet Explorer and then click Internet Explorer in the list of search results to launch the Web browser.
Click the gear icon and select About Internet Explorer from the menu to display the About Internet Explorer dialog. This dialog contains important information about IE, such as the full version, update versions and product ID.
Uncheck the Install new versions automatically box to prevent Microsoft from updating Internet Explorer 11. Click Close to close the About Internet Explorer dialog. Changes are applied immediately; you don't need to restart the Web browser or your computer.
Open the Toolkit to Disable Automatic Delivery of Internet Explorer 11 page and click the Download button.
Click the Run button to run the program when Internet Explorer warns you that the file may be dangerous, or the Save button to save the file and use it later.
Click Yes to accept the License Agreement and then click Browse to select the destination folder. Click OK to install the program; it contains just three files and is less than 100KB in size.
Open the folder that contains the program in File Explorer, hold Shift, right-click on an empty spot and select Open command window here to open a Command Prompt. The Command Prompt uses the selected folder as the working folder automatically; you don't need to run any additional commands.
Type IE11_Blocker.cmd /B into the Command Prompt and press Enter to run the command and block the deployment of Internet Explorer 11 on your computer. The "The operation completed successfully" message is displayed if the command runs successfully.
To unblock the deployment of IE 11, run the IE11_Blocker.cmd /U command. The IE11_Blocker.cmd /H command displays the help information.
To block or unblock the deployment of Internet Explorer 11 on a remote machine, use the IE11_Blocker.cmd Machine_Name /B or IE11_Blocker.cmd Machine_Name /U command. Replace "Machine_Name" with the name of the remote computer.
Tips & Warnings
- According to Microsoft, downgrading to Internet Explorer 10 in Windows 8.1 is not possible. Internet Explorer 11 is the default Web browser in Windows 8.1.
- The Blocker Toolkit creates a new Registry key in the Windows Registry. Although you could theoretically create the key yourself, manually editing the Registry can lead to major problems with programs or the operating system.
- You don't need to disable the Windows Update service to prevent Internet Explorer from updating.
