If you own a Razer mouse or keyboard, you probably have the Razer Synapse software installed. By default, every time you start your PC, a "Razer" splash screen is automatically displayed. How to stop the popup.
We did this with Razer Synapse 3. If you are using an older version of Razer Synapse, the UI may look different.
To find the option, locate the green Razer icon in your right-click in the notification area and select Settings. The icon may be hidden behind the up arrow to the left of the icons in the taskbar. Under Welcome Screen, click Show on Startup. The splash screen will not be displayed when you log in to your PC.
That was – you do not have to click anything else. Your changes will be saved immediately.
You can now close the settings window by clicking the X button in the top right corner and then closing the Razer Synapse window.
 If the splash screen continues to be displayed even after you disable this option, you probably have an outdated version of Razer Synapse installed. At some point in time, a bug caused the splash screen to be displayed even if this option was disabled.
Use the Check for Updates option in the notification icon shortcut menu to check for updates for Razer Synapse, Razer Cortex, and others latest software. To resolve this issue, install the latest versions.
