So, what’s your point? I mean, I probably have a newer version of Chrome and I just finished clearing all my browsing histories, (several browsers), as well as cache and all that. Then I restarted the computer, (windows 7 HP 64bit on a high perf desktop), and these two ‘gray squares overlapping each other is the icon that now shows up in the Google gmail taskbar.
It says the same thing, (about the ‘handler’ message), and I wanted to know what it’s really asking. So here I am and now I’ve read your paragraph or two and have no idea what you’re trying to say… I mean, are you suggesting something?
The post was written when feature was not readied for users, now it is. Now all you need to do when next time that protocol handler icon appears on address bar click on it which shows dialog “allow Gmail(mail.google.com) to open all email links with options as Use Gmail, No and Ignore. You can select No or ignore from the dialog. Choosing ignore may show same icon again for same Gmail account, but when you choose “No” that service handler icon won’t apepar in future again. Rich hope I’ve cleared your doubts.

I don’t see the double diamond icon. Nor do I see a way I can open the service handler. Has Gmail or Chrome updated or changed these options? I can change my Windows 10 email client. But I don’t know if changing this to Chrome will enable Windows to also change the default e mail client.
