What is ghub.exe?

ghub.exe is the Logitech G HUB desktop client that configures and updates supported devices like mice, keyboards, and headsets. It loads the main UI and multiple background services to apply lighting profiles, macro mappings, and firmware updates across connected devices. This article explains safety, behavior, and troubleshooting.

ghub.exe operates with a multi-process design: a UI process handles user input while background services monitor device status, lighting, and firmware checks. It communicates over USB HID and uses persistent tasks to apply settings in real time without blocking the main interface.

Quick Fact: Logitech G HUB uses modular processes to manage devices efficiently; lighting changes are applied through background services to keep the UI responsive.

Types of ghub.exe Processes

UI Process: Main ghub.exe window and user interface
Background Service: Monitors devices, profiles, and firmware updates
Device Communication: USB/HID communication with peripherals
Lighting Engine: Applies per-device lighting and effects
Profile Sync Engine: Synchronizes saved profiles to the cloud and devices
Firmware Updater: Checks and applies device firmware updates

Is ghub.exe Safe?

Yes, ghub.exe is safe when it's the legitimate Logitech G HUB file installed from Logitech's official sources (logitech.com or bundled with your device).

Is ghub.exe a Virus or Malware?

The real ghub.exe is NOT a virus. Malware may masquerade with similar names; always verify its location and signature.

How to Tell if ghub.exe is Legitimate or Malware

File Location: Must be in C:\Program Files\LGHUB\ghub.exe or C:\Program Files (x86)\LGHUB\ghub.exe. Any ghub.exe elsewhere is suspicious.
Digital Signature: Right-click ghub.exe -> Properties -> Digital Signatures. Should show a Logitech signature (e.g., "Logitech" or "Logitech Europe S.A.").
Resource Usage: Normal usage is 2-12% CPU with UI activity and 50-250 MB total memory. Constant high resource use when idle is suspicious.
Behavior: ghub.exe should run when G HUB is active or when you launch the UI. Persistent background activity without user action warrants malware checks.

Red Flags: If ghub.exe is located in unusual folders (like Temp or AppData), runs constantly without UI, lacks a valid signature, or uses resources abnormally, scan with antivirus. Look for similarly named files like "ghub32.exe" from untrusted sources.

Why Is ghub.exe Running on My PC?

ghub.exe runs because Logitech G HUB is active or configured to start with Windows, and its background services keep device information, lighting, and firmware up to date.

Reasons it's running:

Active G HUB UI: You have the G HUB window open and actively configuring devices.
Background Device Monitoring: G HUB runs background services to monitor connected devices for changes in lighting, performance, or firmware.
Startup Auto-Launch: G HUB is configured to launch automatically on Windows startup or device connection.
Profile Synchronization: G HUB syncs device profiles to cloud storage and across devices, triggering background activity.
Firmware Checks: G HUB checks for and applies firmware updates when available, which can run discreet background tasks.

Can I Disable or Remove ghub.exe?

Yes, you can disable ghub.exe. You can stop it from running, change startup behavior, or uninstall the software entirely if you prefer another configuration utility.

How to Stop ghub.exe

End ghub.exe: Open Task Manager (Ctrl+Shift+Esc), find ghub.exe, right-click End Task.
Close G HUB UI: Close the G HUB window to stop active UI processes.
Disable Startup: Task Manager > Startup tab > locate Logitech G HUB and click Disable.
Stop Background Service: Open Services (services.msc), locate 'LGHUB Core Service' or similar, and Stop.
Disable Background Tasks: In G HUB Settings > General, turn off 'Launch at Windows startup' and 'Run in background' if available.

How to Uninstall G HUB

✔ Windows Settings → Apps → Apps & Features → Logitech G HUB → Uninstall
✔ Control Panel → Programs → Uninstall a program → Logitech G HUB → Uninstall
✔ If you plan to switch to another configuration tool, remove ghub.exe completely and restart

Common Problems: High CPU or Memory Usage

If ghub.exe is consuming excessive resources, try these targeted steps to reduce impact while keeping device control.

Common Causes & Solutions

Too many devices or active profiles: Limit active profiles and disconnect unused devices; update G HUB to the latest version.
Background monitoring: Disable nonessential background monitors in Settings and close unused device panels.
Firmware update checks: Pause firmware checks temporarily if not needed; perform updates manually when convenient.
Outdated software: Update G HUB to the latest version to optimize resource usage.
Corrupted profiles: Export, delete, and re-import profiles; reset to default if necessary.
Conflicting peripherals: Disconnect conflicting devices or re-pair them; check for driver conflicts and reinstall if needed.

Quick Fixes:
1. Open Task Manager (Ctrl+Shift+Esc) and identify high-usage ghub.exe processes
2. Close unused device panels and profiles
3. Update G HUB to the latest version
4. Disable nonessential background tasks in Settings
5. Restart ghub.exe or reboot PC after updates

Frequently Asked Questions

Is ghub.exe a virus?

No, ghub.exe is the legitimate Logitech G HUB application provided by Logitech. Verify its location at C:\Program Files\LGHUB\ghub.exe and ensure a valid signature from Logitech.

Why is ghub.exe using so much CPU?

CPU usage can spike during device scanning, firmware checks, or when adjusting lighting for multiple devices. Use Task Manager (Shift+Esc in G HUB) to identify the source and adjust profiles or disable nonessential devices.

Can I delete ghub.exe?

You can uninstall Logitech G HUB via Windows Settings or Control Panel. Removing ghub.exe will disable device customization and lighting management unless you install an alternative configuration tool.

Can I disable ghub.exe?

Yes. Close the application, stop related services, and disable startup in Task Manager. You can also disable 'Run in background' in G HUB settings if available.

Why does ghub.exe start with Windows?

If you enabled startup options, ghub.exe will launch at login to ensure devices are ready when you connect your peripherals. Disable startup in Task Manager if you don’t want automatic launch.

Why are there multiple ghub.exe processes?

G HUB uses a multi-process architecture to separate UI, device communication, and background services. This helps stability but may show several ghub.exe processes in Task Manager.
