Hi all,

I haven't checked this on xp but it appears so far it is the Vista users being affected to that's where my interest is.

I use an lagacy registry class to pick the default email client and the code looks for a key in registry's "mailto\shell\open\command" in Classes Root.

This works fine most of the time. The default email client on Vista is Windows Mail. If a customer upgrades or installs Windows Live Mail, and sets it as default email client, the key above still points to Windows Mail.

Any advice please on where I should be looking instead or where else I should be looking. The ShellExecute works fine and it does pick the right client so it must be lodged some, any ideas will be much appreciated.

Thank you
