While there are several ways to configure this, the easiest way that I have encountered is via the Mailto Updater application. All you need is a single click and it will configure your Windows to run Gmail (in browser) as the default email client. What’s more, it supports Google apps too. Here’s what you need to do: 1. Download MailTo.exe 2. Run the application (by double click on it) 3. A window will appear. Select whether you want it to set the normal Gmail site or your Google App domain as the default email account. For Google Apps, you will need to enter your domain name.

  1. Lastly, click “Apply setting”. That’s it. From now on, whenever you click on a mailto link in Windows, your default browser will launch and load the Gmail compose page (if you are logged in) with the email address and subject. What other ways do you use to configure Gmail as the default application in Windows?
