If you have a Razer mouse or keyboard, you probably have installed the Razer Synapse software. By default, a "Razer" startup screen automatically appears each time you start your PC. Here's how to stop the popup.
We did this process with Razer Synapse 3. If you have an older version of Razer Synapse, the interface may look different.
To find the option, look for the green Razer icon in your notification area, right-click on it and select "Settings". The icon can be hidden behind the up arrow to the left of the system tray icons.
Uncheck the "Show on Startup" option under Splash Screen here. The startup screen does not appear when you connect to your PC.
That's all, it's not necessary to click on something else. Your changes are saved immediately.
You can now close the settings pane by clicking the X button in its upper right corner, and then close the Razer Synapse window.
If you still see the startup screen even after disabling this option, an outdated version of Razer Synapse is probably installed. At one point, a bug was causing the startup screen to display, even when this option was disabled.
Use the "Check for Updates" option in the notification icon's pop-up menu to check for updates to Razer Synapse, Razer Cortex, and other recent software. Install the most recent versions to resolve this problem.
