What Is Logitech G HUB? Is It Safe to Disable at Startup?

What Is Logitech G HUB?

Logitech G HUB is Logitech's configuration app for supported gaming devices such as mice, keyboards, headsets, microphones and some lighting accessories. It is used to manage DPI settings, button assignments, macros, RGB lighting, audio options and per-game profiles.

On Windows, lghub.exe is the main app process. On macOS, G HUB also installs background components so profiles and device features can load automatically.

If you use Logitech gaming hardware and rely on custom bindings, automatic profile switching or lighting effects, G HUB may need to start with the system. If you only open it occasionally to change settings, it does not usually need to run all the time.

Is It Safe?

Yes — if it is the real Logitech app. Logitech G HUB is legitimate software from Logitech.

If you want to verify it, check that the app is installed in a normal Logitech location such as under Program Files on Windows, and confirm the file's digital signature shows Logitech as the publisher. Be more cautious if lghub.exe is running from an unusual folder such as Downloads, Temp or a user-writable app data path you do not recognize.

G HUB is not a Windows or macOS system component. Disabling it will not break the operating system, but it can stop Logitech-specific features from loading automatically.

Should I Disable It at Startup?

Usually, startup is optional.

Keep it enabled at startup if:

• you use Logitech macros or custom button mappings
• you want per-game profiles to switch automatically
• you use RGB lighting or headset settings that depend on G HUB
• your device does not keep your preferred settings in onboard memory

Disable it at startup if:

• you rarely change device settings
• your mouse or keyboard works fine with onboard profiles
• you want fewer background apps loading at sign-in

Disabling startup usually means the hardware still works as a basic mouse, keyboard or headset. You may just lose advanced features until you open G HUB manually.

Why Is It Using High CPU or Memory?

Short spikes can happen when G HUB starts, scans for supported devices, updates profiles or checks connected hardware. Higher usage may also appear after an app update, when a device reconnects, or if profile syncing is stuck.

If usage stays high:

• quit and reopen G HUB
• disconnect and reconnect the Logitech device
• check for a G HUB update
• reduce or remove complex lighting effects
• review whether another Logitech component is also running
• restart the computer

If the process keeps using heavy CPU for long periods, reinstalling G HUB may help. If lghub.exe is in an unusual location, investigate it rather than assuming it is genuine.

How to Disable or Remove It

On Windows, you can disable G HUB from Startup in Task Manager or Settings, or remove it from Apps if you no longer use it. If you uninstall it, your Logitech device should still function with basic input support, but custom features may stop working.

On macOS, disable its login or background launch entry in system login/background items, or uninstall G HUB from Applications using Logitech's uninstaller if included.

If you are unsure, disable startup first and test your device before uninstalling.

Where Kudu Helps

Kudu can show whether Logitech G HUB is set to launch at sign-in and lets you disable or re-enable that startup entry without uninstalling the app. On Windows, Startup Manager can also show boot impact when available.

If G HUB seems busy, Kudu's Performance Monitor can confirm whether lghub.exe is the process using CPU or memory and help you compare it with other background apps. If you suspect a fake lghub.exe, Kudu's Malware Scanner can help check for suspicious persistence or known malicious patterns, but it complements your antivirus rather than replacing it.
