How to Enable Fast Start

Fast Start is a method to make SignalRGB launch earlier in the Windows startup sequence by adding it to the Userinit registry key. This causes SignalRGB to start alongside Windows Explorer rather than waiting for the normal autostart queue, which can reduce the delay between logging in and your lighting becoming active.

Caution

This method involves editing the Windows registry. Follow the steps exactly — an incorrect registry edit can affect Windows startup behavior. If you are uncomfortable with registry editing, use the standard startup method in Settings > Windows Settings > Startup Behavior instead.

Before You Start

• Administrator access to your Windows account
• SignalRGB installed
• Know your SignalRGB version number (visible in Settings > About)

How to Enable Fast Start

1. Press WIN + R, type regedit, and press Enter to open the Registry Editor.
2. Navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
3. Find the Userinit value in the right pane and double-click it.
4. The default value is: C:\Windows\system32\userinit.exe,
5. Add the SignalRGB launcher path to the end of the existing value, separated by a comma: C:\Windows\system32\userinit.exe,C:\Users\USERNAME\AppData\Local\VortxEngine\SignalRgbLauncher.exe --silent, — replace USERNAME with your actual Windows username.
6. Click OK and close the Registry Editor.
7. Restart your PC to test.

Tip

The --silent flag prevents SignalRGB from showing the splash screen on startup. Remove it if you want the window to open on launch instead of starting minimized to the tray.

How to Disable Fast Start

1. Open the Registry Editor and navigate back to the Winlogon key.
2. Double-click the Userinit value.
3. Remove the SignalRGB portion of the value, leaving only: C:\Windows\system32\userinit.exe,
4. Click OK and restart your PC.
