G HUB Service restart guide

This guide focuses on G HUB problems when the application becomes unresponsive during startup, displaying a continuously spinning logo.

• Windows
• macOS

On Windows

G HUB uses a service to perform important operations. Sometimes, that service can get stuck and as a result G HUB presents a spinning G Logo.

Step 1: Close G HUB completely

1. Right-click the G HUB icon in your system tray (bottom-right corner of screen)
2. Select "Quit" from the menu
3. Verify closure: Ensure the G HUB window is completely closed

Step 2: Access the Task Manager

• Press Ctrl + Alt + Del and select "Task Manager"
• Alternative: Press Ctrl + Shift + Esc for direct access
• If you see a simplified view, click "More details" at the bottom

Step 3: End G HUB Processes

1. Click the "Processes" tab
2. Look for these processes and end them in this order:
   • "LGHUB Agent" → Right-click → "End task"
   • "LGHUB" → Right-click → "End task" (all of them)
3. Note: Leave "LGHUB Updater" running

Step 4: Restart G HUB Service

1. Click the "Services" tab in Task Manager
2. Locate "LGHUBUpdaterService"
3. Right-click → Select "Restart"
4. Wait 10-15 seconds until the Status shows "Running"

Step 5: Launch G HUB

Open G HUB through:

• Start Menu → Search "G HUB"
• Desktop shortcut (if available)
• System tray (if icon reappears)

If the Issue Persists

Option 1: System Reboot

A full computer restart often resolves service issues.

Option 2: Advanced Troubleshooting

If you're using an administrator account and the problem continues, refer to our G HUB Advanced Troubleshooting guide.

On macOS

Step 1: Close G HUB Completely

1. Right-click the G HUB icon in your menu bar (top-right corner of screen)
2. Select "Quit G HUB" from the dropdown menu

4. Wait 10-15 seconds for processes to fully terminate
