    Nice thought; doesn’t work.

    At Thunderbird > Tools > Options > Advanced: neither of the System Integration boxes is ticked.

    Using Windows 7 Professional, Control Panel > Default Programs > Set Default Programs > Thunderbird: “This program has 0 out of 4 defaults”, which – I’m assuming – means it’s not set as the default.

    Yet I still get the system integration prompt each time I open Thunderbird.

    I second Mr. Ghostwolf
    (Is that inspired by ThreeHowlingWolf by any chance)

    Using Windows 8.1 and Thunderbird 24.1.0
    On each start it asks again. I also tried starting as Administrator in the hope that it would be able to store the option I choose (skip integration)
    All the flags are unticked.

    To get rid of the System Integration prompt, uncheck all options (Email, etc.) and then click Set as Default. Close and then reopen Thunderbird. The prompt should be gone.

    Thanks Dave, that works! Very unintuitive though!

    Yeap, Dave’s solution is indeed the only working solution!!!
    thanks

    Which actually means that if you do not set Thunderbird as your default Email they will keep pesting you forever. Or until you do.
