Running multiple versions of Internet Explorer on a single instance of Windows is unsupported

Summary

Running multiple versions of Windows Internet Explorer, or portions of Windows Internet Explorer, on a single instance of Windows is an unlicensed and unsupported solution. We strongly discourage using any solution or service (hosted or on-premises) that repackages the executable components of Internet Explorer, or portions of those components, into a separate installation. If you try to reconfigure Windows so that it runs multiple versions of Internet Explorer from these kinds of packages on a single instance of Windows, your configuration will not be supported by Microsoft Customer Support Services.  

This includes solutions that try to incorporate application-level virtualization to run multiple repackaged versions of Windows Internet Explorer on a single operating system instance.

More Information
Microsoft supports solutions that enable the virtualized use of multiple versions of Windows Internet Explorer through a separate operating system installation. This means that only one instance of Windows Internet Explorer is supported per operating system.

Microsoft offers best practices, guidance, and tools to help customers migrate from Windows Internet Explorer 6 to Windows Internet Explorer 8. For more information, visit the following Microsoft websites:
