On recent versions of Windows, Internet Explorer is a 64 bit process but by default tabs are spawned as 32 bit processes. It is up to the user to change Internet Options to enable full 64 bit mode.

I need a reliable way to detect whether a users Internet Explorer is configured to run in full 64 bit or 32 bit mode.

I'm stumped. Is this possible?

Cheers,
