For example:

Host machine has IE8 installed locally. Start page is say google.com

Virtual IE8 start page is say, msn.com

If I start Virtual IE8, I get msn.com, then if I start Host IE8, it inherits the registry of the virtual environment and sets the start page to msn.com instead of google.

This applies to almost all of the IE8 Settings. It also works in reverse.
Start Local IE8, then Virtual inherits the startpage (and other registry settings) of the local.

I've tried setting the start page Registry Key to Full Isolation, but it changes nothing.

What's up with this? Is IE just using the settings in memory? Any thoughts on a work around on this?

Thanks!
