How can I use Gmail (in Chrome) as the default email handler in Windows 8?

I used to use GmailNotifier in Windows 7, but that doesn't seem to work anymore. Clicking on a mailto: link simply opens Chrome with a blank page.

I am not interested in using the Mail app built into Windows 8.

Open Gmail in Chrome. Then see this. Click on the eye in the address bar.

I tried that, but it doesn't work, even when clicking a mailto link within Chrome :( – Leftium Dec 28 '12 at 2:29
@Leftium Can you see the options of screenshot? Have you selected Use Gmail? And, what's the version of your Chrome? – Evil Angel Feb 1 '13 at 20:01
hmmm.. this seems to work, now. I'm not sure what changed since the last time I tried it~ – Leftium Mar 18 '13 at 5:12
Ah that's great! – pratnala Mar 18 '13 at 10:48
@Entrodus Done. Added the additional instruction – pratnala Apr 10 '14 at 10:11
  1. Close Chrome
  2. Open C:\Users\<your username>\AppData\Local\Google\Chrome\User Data\Local State with Notepad (or, any other text editor).

  7. Open Default Programs.
    Search for Default Programs

This is fantastic! Can it be done with Firefox? – pilau Feb 11 '14 at 19:58
Thanks for taking the time to reply, but it seems that it cannot be done in Firefox (otherwise I'm missing something). – pilau Feb 13 '14 at 11:13

Follow the steps after installation of Gmail Client enter image description here enter image description here enter image description here

Change your Default Client to Gmail..

There is no Gmail option! – Leftium Nov 4 '12 at 8:32
@Leftium see my answer – pratnala Dec 27 '12 at 10:41

See the below link. It expands upon Sant14's answer by first having you create the necessary entry that would then show up in your 'Default Programs' > 'Programs' list.

I found an easier solution. The link below installs an applet which gives you the option as a check box, and you don't have to use Chrome. I'm using Firefox because I have some sort of virus on Chrome that hijacks clicks and sends me to advertisements.
