What is LGHUB.exe?
LGHUB.exe is the executable for Logitech G HUB software, which lets you customize lighting, macros, and profiles for compatible Logitech gaming devices. It typically runs as a desktop application and may spawn background processes to manage devices, lighting effects, and on‑the‑fly configuration updates.
G HUB uses a modular architecture where the UI, background service, lighting engine, and device monitor run as separate processes. This separation helps apply lighting changes quickly while keeping the UI responsive and reducing cross‑process interference.
Quick Fact: Logitech G HUB centralizes device customization, profiles, and lighting across supported keyboards, mice, and headsets, and can synchronize settings between connected devices.
Types of G HUB Processes
- G HUB UI: Main application window and profile editor
- Background Service: Keeps device states and lighting synced while the app is running in background
- Lighting Engine: Controls RGB lighting for connected devices
- Device Monitor: Detects connected Logitech devices and loads their profiles
- Update Checker: Checks for software updates and applies patches
Is LGHUB.exe Safe?
Yes, LGHUB.exe is safe when downloaded from official Logitech sources (logitech.com or the Logitech Setup software).
Is LGHUB.exe a Virus or Malware?
The real LGHUB.exe is NOT a virus. Malware may impersonate the name, so verify the file 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 located at
C:\Program Files\LGHUB\LGHUB.exe (or the (x86) path) -> Properties -> Digital Signatures. Should show a Logitech signer such as "Logitech Europe S.A." or "Logitech International S.A.".
- Resource Usage:: Normal usage is 2-12% CPU and 60-200 MB memory when active. Constant high usage when idle is suspicious.
- Behavior:: G HUB should be active only when you run the app or when a connected device triggers it. If it auto-launches and consumes resources without user action, investigate.
Red Flags: If LGHUB.exe is located in unusual folders (like Temp, AppData\Local, or System32), runs when Windows starts without user action, has no valid digital signature, or uses high CPU constantly, scan with antivirus immediately. Beware of similarly-named files like "lghub.exe" in untrusted folders.
Why Is LGHUB.exe Running on My PC?
LGHUB.exe runs when you open Logitech G HUB or when Windows starts if you enabled startup. It also runs background services to maintain device profiles and ensure lighting and macros apply correctly to connected devices.
Reasons it's running:
- Active Configuration Use: You're actively configuring devices or applying lighting and macro profiles; LGHUB runs to apply changes in real time.
- Background Sync and Profiles: G HUB syncs device settings and lighting across devices, which keeps services running in the background.
- Startup Launch: LGHUB is set to start automatically at Windows login to enable immediate device customization.
- Device Detection: Connecting compatible Logitech devices triggers LGHUB to initialize drivers and load profiles.
- Lighting and Macro Processing: Real‑time lighting and macro changes require ongoing processing, even when the UI is minimized.
Can I Disable or Remove LGHUB?
Yes, you can disable LGHUB. It may stop lighting effects and profile syncing, but you can re‑enable it later or uninstall if you no longer use Logitech devices.

- Exit from System Tray: Right‑click the LGHUB system tray icon and choose Exit or Quit.
