Then click on the Accounts option to add the new Google Gmail account. Finally, if you already have another email account configured in Mail, then use the Windows+ I keyboard combination (Hold the Windows key and the I key at the same time) to open the Mail Settings screen.
If you used a different email provider for your Microsoft Account then click on the Google option under the Add your email accounts section. If you used your Gmail address as the email address for your Microsoft Account, you will automatically be prompted to add the Google account to Windows 8. Otherwise, enter your account information and click on the Save button. If you do not have a Microsoft Account, please click on the Sign up for a Microsoft Account and create one. If you have not previously used the Mail app you will be presented with a screen asking for your Microsoft Account information.
This will launch the Mail app, which you will be using to set up your Gmail account. To add Gmail to Windows 8, click on the Mail tile in the Windows 8 Start Screen.
