Make mailto links open in Gmail in Google Chrome browser (Windows 7 & Vista)

Windows 7 and Vista

• Open your registry editor (Type “regedit” at your start menu)
• Navigate to HKEY_CLASSES_ROOT\mailto\shell\open\command

(If this key does not exist then create it by right clicking HKEY_CLASSES_ROOT and selecting new key, type mailto and press enter, repeat for the rest of the keys in the path above.)

• Edit the (Default) command from whatever it is (right click and select modify) to:

“C:\Users\UserName\AppData\Local\Google\Chrome\Application\chrome.exe" https://mail.google.com/mail?extsrc=mailto&url=%1

(with “UserName” being your username.)

Open with Google Apps

Instead of:

“mail.google.com/mail?"

substitute in the following:

“mail.google.com/a/yourdomainhere.com?
