Google has yet to create a Gmail app for Windows. The closest solution is to add a Gmail account to the Microsoft Outlook email desktop client. If you already use Office 365, you probably know that Outlook supports the use of multiple email accounts simultaneously. Here's how you can add your Gmail account to the Outlook desktop client: 1. Open Outlook and then select “File” from the main toolbar. You’ll find the “+Add Account” button in the top left corner. 2. Type in your Gmail address and click on "Connect." Outlook will automatically launch the Gmail window and ask you for the password. 3. When you enter your password, click on the "Sign in" option. If you've previously set up 2-factor authentication on Gmail, you'll be asked to enter a code that will be sent to your mobile device. 4. When Outlook finishes adding your Gmail account, select “Done.” Outlook will sync with your Gmail account automatically. The process may take a while. Furthermore, you might receive an email in your Gmail inbox notifying you that there is a new logon. This is to be expected, and you can just ignore it and proceed.
