How to show Welcome Screen when IntelliJ IDE get opened or closed

Question

When opening IntelliJ IDEs, they just opened with the last modified project. How can I set to show Welcome Screen?

Answer

Go to Settings | Appearance & Behaviors | System Settings, and disable "Reopen projects on startup".

Notice

After disabling this option, everytime opening IntelliJ IDEs or closing IntelliJ IDEs from working projects, the welcome screen will be shown. **Welcome Screen to be shown after closing IntelliJ IDE is available in MacOS. If it's enabled, the Welcome screen can only be shown by clicking File | Close Project.
