There were changes in recent Windows versions and now, there are more places in registry which will further override shell associations from Classes. Registry entries for mailto protocol are under HKLM\SOFTWARE\Classes\mailto and as it is with other Classes, they could be overridden by entries for CURRENT_USER, under HKCU\SOFTWARE\Classes\mailto Quoting the relevant paragraph for your question, from papo's answer: I would most appreciate if anyone would share reliable information or documentation that explains this topic! Maybe there is a Win32 API function that returns the correct value?įor Windows 10, this seems to be different - see the discussion here: So when did this change? Has the wrong value on machine B any meaning? If not, why does it get written there in the first place? Does the mix of 64bit and 32bit email clients on the same computer change anything? When looking at the plethora of information that points to HKLM\Software\Clients\Mail, it seems obvious that previous versions of Windows handled this differently and always wrote to that location.

If the suggestions on this page do not solve your problem, consult the specific application or operating system's documentation for instructions on how to set the default email client.

Unfortunately, there is a great deal of variability among operating systems and applications regarding how the default mail client is specified. For example, when you click an email address link (like " on a web page or invoke a mail function (such as "Send to") from a word processor, Thunderbird will launch and open a message composition window. If Thunderbird is specified as your system's default email application, it will integrate with other applications (such as word processors and web browsers).
