There are two (2) ways to relaunch ggLeap after going into Admin mode.
Method One (secured)
Simply restart the PC. This is the preferred (and recommended) method to use because it will allow ggLeap to start-up in shell mode.
Alternatively, you can also sign out your Windows user and sign back in. Press Ctrl + Alt + Del on the keyboard simultaneously and click "Sign Out", then on the Windows User login screen, click "Sign In".
Method Two (unsecured)
1. Open Task Manager and then look for clientinterface.exe. Right-click on it and select "End task" on the menu.
2. Go to Drive C, locate the ggLeap folder, and re-launch clientInterface.exe.
NOTE: If ggLeap is launched in unsecured mode, the Windows taskbar/system tray will be accessible to the user.
