Based on this helpful comment, I followed these instructions to set IE Mode for a .NET process that's using the embedded IE web control. However, 8000 and 8888 values don't guarantee IE 8 mode. They set the embedded browser to identify itself as the latest IE version installed on the system. So, if I have IE 9 installed I can see the agent string in the http request as IE 9. If 10 then 10. Are there other values or settings to change to force IE 8 mode even if IE 9 or greater is installed?
