What is lghub.exe?
lghub.exe is the executable for LGHUB, Logitech's peripheral management software. It configures mice, keyboards, and other devices, applies lighting schemes and macros, and stores user profiles. The process often runs as multiple components, including a GUI and background services.
LGHUB employs a modular architecture with a main GUI process and several background components to manage device detection, profile synchronization, and firmware checks. This separation improves responsiveness and ensures device configuration persists across sessions.
Quick Fact: LGHUB introduced per-device profile management and cloud synchronization to keep lighting and macros consistent across different machines.
Types of LGHUB Processes
- Main GUI Process: Handles the LGHUB window and user interactions (1 instance)
- Device Profile Manager: Manages per-device settings, lighting, and macros (multiple instances)
- Background Sync Service: Synchronizes profiles with Logitech cloud services
- Firmware Update Helper: Checks and applies firmware updates to connected devices
- Telemetry/Diagnostics Helper: Gathers usage data for diagnostics (optional)
Is lghub.exe Safe?
Yes, lghub.exe is safe when it's the legitimate file from Logitech downloaded from official sources (logitech.com or pre-installed by manufacturer).
Is lghub.exe a Virus or Malware?
The real lghub.exe is NOT a virus. Malware can masquerade with similar names, so verify location and signature.
How to Tell if lghub.exe is Legitimate or Malware
- File Location: Must be in
C:\Program Files\LGHUB\lghub.exe or C:\Program Files (x86)\LGHUB\lghub.exe. Any lghub.exe elsewhere is suspicious.
- Digital Signature: Right-click the file in Explorer → Properties → Digital Signatures. Should show signer "Logitech".
- Resource Usage: Normal usage is 3-15% CPU per process, 150-500 MB total memory. Extremely high usage when idle is suspicious.
- Behavior: LGHUB should run when you use Logitech devices or at startup if configured. Unexpected background activity warrants a malware scan.
Red Flags: If lghub.exe is located in unusual folders (like Temp, AppData\Roaming, or System32), runs when Logitech software isn't open, has no digital signature, or uses constant high resources, scan with antivirus immediately. Be wary of similarly-named files like "lghub.exe" from untrusted sources.
Why Is lghub.exe Running on My PC?
lghub.exe runs when you actively use LGHUB to configure devices, or when LGHUB is configured to start at Windows login and manage background tasks like profile sync and firmware checks.
Reasons it's running:
- Active LGHUB Use: You're configuring devices, lighting, or macros; the GUI and related helpers run to apply changes in real time.
- Background Device Monitoring: LGHUB monitors connected peripherals for firmware updates and profile changes, spawning services as needed.
- Cloud Sync and Profile Updates: LGHUB syncs devices and lighting profiles with the Logitech cloud, which can keep processes active in the background.
- Startup Launch: LGHUB can be configured to start with Windows, causing lghub.exe to run at login even if unused afterward.
- Firmware Update Checks: Periodic checks for device firmware updates may initiate background tasks and temporary processes.
Can I Disable or Remove lghub.exe?
Yes, you can disable lghub.exe. It's safe to close LGHUB when not in use, and you can uninstall it entirely if you prefer a different peripheral manager.
