What is ghub.exe?
ghub.exe is the executable for Razer G HUB, a centralized device configuration and lighting management application. It loads when you sign in or when Razers peripherals are connected, and it manages profiles, macros, and RGB effects across supported devices.
G HUB uses modular processes: a main GUI, device drivers, lighting engine, and cloud sync. This architecture supports real-time device control, profile switching, and per-device settings while keeping components isolated for stability.
Quick Fact: Razer introduced G HUB to unify device customization after the legacy Synapse era, providing cross-device lighting with cloud-backed profiles.
Types of ghub Processes
- Main GUI Process: User interface, settings, and profile management (1 instance per user)
- Device Driver Loader: Loads and communicates with connected Razers peripherals
- Lighting Engine: Renders RGB effects and per-device lighting in real-time
- Cloud Sync Service: Syncs profiles and settings with Razer accounts
- Macro/Profile Engine: Applies macros and per-application profiles
- Background Updater: Checks for software updates and firmware updates
Is ghub.exe Safe?
Yes, ghub.exe is safe when it's the legitimate file from Razers official sources (razer.com or the Microsoft Store distribution if applicable).
Is ghub.exe a Virus or Malware?
The real ghub.exe is NOT a virus. Malware may masquerade as ghub.exe, so verify the path and signature.
How to Tell if ghub.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\Razer\G HUB\GHub.exe or C:\Program Files (x86)\Razer\G HUB\GHub.exe. Any ghub.exe elsewhere is suspicious.
- Digital Signature:: Right-click ghub.exe in Explorer → Properties → Digital Signatures. Should show a signature from "Razer Inc.".
- Resource Usage:: Normal ghub.exe usage is 2-15% CPU with the GUI active and modest memory. Constant high usage when idle is suspicious.
- Behavior:: G HUB should run only when your peripherals are connected or you launch the app. Persistent background activity when idle may indicate malware.
Red Flags: If ghub.exe is located in unusual folders (Temp, AppData), runs when you are not using Razers peripherals, has no valid digital signature, or uses excessive resources constantly, scan with reputable antivirus. Watch for similarly-named files like "ghubium.exe".
Why Is ghub.exe Running on My PC?
G HUB starts when you sign in or when Razers peripherals are connected, and it may run in the background to maintain profiles and firmware connections.
Reasons it's running:
- Active Peripheral Configuration: You are actively configuring lighting, macros, or device profiles, which keeps ghub.exe active to apply changes.
- Background Profile Sync: G HUB syncs device profiles with your Razers account to preserve customization across sessions.
- Startup Launch: Windows is configured to launch G HUB at startup to ensure devices are ready when you log in.
- Driver and Firmware Checks: G HUB loads device drivers and may check for firmware updates in the background.
- Macro and Application Triggers: Macro engines monitor application focus to apply per-app profiles or key mappings as configured.
Can I Disable or Remove ghub.exe?
Yes, you can disable ghub.exe. You can close the application, prevent startup, or uninstall if you don’t need Razer device customization anymore.
How to Stop ghub.exe
- Exit from System Tray: Right-click the G HUB icon in the system tray and choose Exit or Quit.
- Close Application Windows: Close all G HUB windows to stop active processes.
- Disable Startup: Task Manager → Startup tab → Disable Razer G HUB.
- Stop Background Services: Open Services.msc, locate G HUB Service and set Startup type to Manual or Disabled.
- Adjust In-App Settings: In G HUB, go to Settings → General → uncheck 'Launch on system startup' and similar options.
How to Uninstall ghub
- ✔ Windows Settings → Apps → Apps & features → Razer G HUB → Uninstall
- ✔ Control Panel → Programs → Uninstall a program → Razer G HUB → Uninstall
- ✔ Reboot the PC after uninstall and remove any residual folders under C:\Program Files\Razer and C:\Users\Public\Documents\Razer
Common Problems: High CPU or Memory Usage
If ghub.exe is consuming excessive resources:
Common Causes & Solutions
- Too Many Peripherals Registered: Disconnect unused devices and remove stale Profiles to reduce constant polling.
- Outdated G HUB Version: Update G HUB to the latest version from razer.com/downloads or within the app.
- Corrupted Profiles: Back up and reset profiles; consider deleting problematic profiles and reimporting clean ones.
- Background Sync: Disable cloud sync temporarily to see if resource usage drops.
- Driver Conflicts: Update device drivers via Device Manager or reinstall G HUB.
- Large Lighting Data: Reduce lighting effects complexity or disable dynamic RGB layers.
Quick Fixes:
1. Quick Fixes:
2. 1. Open G HUB and review connected devices; remove unused peripherals
3. Update G HUB to the latest version
4. Restart G HUB service and reapply profiles
5. Clear Caches within G HUB or reset settings to defaults
6. Disable startup to test resource impact
