If GHub.exe is crashing, not opening, or causing errors on your Windows PC, the fastest fix is usually a clean reinstall after deleting leftover files from your AppData folder. But there are several causes, and each has its own fix. This guide walks you through all of them, step by step.
What Is GHub.exe and Why Does It Break?
GHub.exe is the main executable for Logitech G HUB, the software that controls Logitech gaming peripherals like mice, keyboards, and headsets. It handles RGB lighting, DPI settings, macros, and device profiles.
It breaks more often than it should. Common reasons include:
- Corrupted installation files
- Conflicts with Windows services or startup processes
- Outdated or broken drivers
- Leftover registry entries from old installs
- Windows Update changing system permissions
- Conflicts with antivirus software
The good news is that most of these are fixable without any technical background.
Quick Answer: The Fix That Works for Most People
Before going through every method, try this first. It solves the problem for roughly 70% of users.
Step 1: Uninstall G HUB from Control Panel. Step 2: Delete leftover folders in AppData. Step 3: Reinstall the latest version from Logitech’s website.
That is it. If that does not work, keep reading. The sections below cover every known cause and fix.
Method 1: Restart the LGHUB Agent Service
Sometimes GHub.exe is running in the background but not responding. Restarting its service can bring it back without a full reinstall.
- Press Ctrl + Shift + Esc to open Task Manager.
- Go to the Details tab.
- Look for lghub.exe, lghub_agent.exe, and lghub_updater.exe.
- Right-click each one and select End Task.
- Wait 10 seconds, then relaunch G HUB from your desktop or Start menu.
If it opens normally now, you are done. If not, move to the next method.
Method 2: Run GHub.exe as Administrator
G HUB sometimes loses permission to access system resources, especially after a Windows Update.
- Right-click the G HUB shortcut on your desktop.
- Select Properties.
- Go to the Compatibility tab.
- Check the box that says Run this program as an administrator.
- Click Apply, then OK.
- Open G HUB and check if it works.
This is a permanent change. Every time G HUB opens, it will run with admin rights.
Method 3: Full Clean Reinstall (The Most Effective Fix)
This is the method that fixes GHub.exe errors caused by corrupt files, bad updates, or broken registry entries.
Step 1: Uninstall G HUB
- Press Windows + R, type appwiz.cpl, and press Enter.
- Find Logitech G HUB in the list.
- Click it and select Uninstall.
- Follow the uninstaller prompts.
Step 2: Delete Leftover Files
This step is critical. The standard uninstaller leaves behind files that cause problems on reinstall.
- Press Windows + R, type %localappdata%, and press Enter.
- Find the folder named LGHUB and delete it entirely.
- Press Windows + R again, type %programdata%, and press Enter.
- Find the folder named LGHUB and delete it.
- Press Windows + R, type %appdata%, and press Enter.
- Look for any Logitech or LGHUB folder and delete it.
Step 3: Delete Registry Entries (Optional but Recommended)
- Press Windows + R, type regedit, and press Enter.
- Navigate to: HKEY_CURRENT_USER\Software\Logitech
- Right-click the Logitech folder and select Delete.
- Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Logitech
- Right-click and delete this one too.
Be careful in the registry. Only delete what is listed above.
Step 4: Restart Your PC
Do not skip this. Restarting clears memory and removes any lingering processes.
Step 5: Download and Install G HUB Fresh
Go to the official Logitech G HUB download page and download the latest installer. Run it and complete the setup.
Method 4: Fix GHub.exe Not Opening at Startup
If G HUB is not launching when Windows starts, or it shows in the taskbar but does not open its window, here is what to do.
- Open Task Manager (Ctrl + Shift + Esc).
- Go to the Startup tab.
- Find Logitech G HUB and make sure its status is Enabled.
- If it is disabled, right-click and select Enable.
Also check this setting inside G HUB itself:
- Open G HUB.
- Click the three horizontal lines (menu) in the top left.
- Go to Settings.
- Make sure Launch at startup is toggled on.
Method 5: Update or Reinstall the Logitech Driver
A broken or outdated driver can cause GHub.exe to fail even when the software itself is fine.
- Press Windows + X and select Device Manager.
- Expand Human Interface Devices or USB Input Devices.
- Find your Logitech device, right-click it, and select Update driver.
- Choose Search automatically for drivers.
If that does not work, uninstall the driver and reconnect your device. Windows will reinstall the driver automatically.
Method 6: Check for Windows Compatibility Issues
G HUB sometimes breaks after major Windows updates. Here is how to check compatibility.
- Right-click GHub.exe (found in C:\Program Files\LGHUB).
- Select Properties, then the Compatibility tab.
- Click Run compatibility troubleshooter.
- Follow the prompts. Windows will test different compatibility settings and tell you which one works.
You can also manually set compatibility mode to Windows 8 if the troubleshooter does not help.
Method 7: Disable Antivirus Temporarily
Some antivirus programs flag GHub.exe or block it from running. This is a false positive, but it happens with Norton, Bitdefender, and McAfee in particular.
- Open your antivirus dashboard.
- Look for a Real-Time Protection or Game Mode toggle.
- Turn it off temporarily.
- Try launching G HUB.
If it opens, add G HUB to your antivirus whitelist or exclusions list so it is not blocked again.
Method 8: Repair the Microsoft Visual C++ Redistributables
G HUB depends on Visual C++ runtime packages. If these are corrupted, GHub.exe will crash on launch.
- Open Control Panel and go to Programs and Features.
- Look for any Microsoft Visual C++ Redistributable entries.
- Right-click each one and select Change, then Repair.
- Restart your PC after repairing.
Alternatively, download the latest Visual C++ Redistributable directly from Microsoft’s official page.
Method 9: Check Windows Event Viewer for Crash Logs
If nothing is working, Event Viewer can tell you exactly why GHub.exe is crashing.
- Press Windows + R, type eventvwr, and press Enter.
- Go to Windows Logs, then Application.
- Look for errors with the source LGHUB or Application Error.
- Click on the error to see the details.
The error message will usually tell you which file or module is causing the crash. Search that specific error online for a targeted fix.

Tips to Prevent GHub.exe Problems in the Future
- Always download G HUB from Logitech’s official website, not third-party sources.
- Do not interrupt a G HUB update while it is installing.
- After a major Windows Update, restart G HUB manually to check it still works.
- Keep one backup of your G HUB profiles by exporting them inside the app.
- If your antivirus auto-updates frequently, periodically verify GHub.exe is still whitelisted.
Conclusion
GHub.exe problems are frustrating, but they are almost always fixable. Start with the simplest fix: end all G HUB tasks in Task Manager and relaunch. If that fails, do a proper clean reinstall by removing AppData folders before installing fresh. For stubborn cases, check permissions, compatibility settings, drivers, and Visual C++ packages.
The most important step most people skip is deleting the LGHUB folder from AppData before reinstalling. That single step makes the difference between a reinstall that works and one that just brings the same problem back.
Frequently Asked Questions
Is GHub.exe safe or is it malware?
GHub.exe is a legitimate Logitech application and not malware. However, malware can sometimes disguise itself using the same name. To verify it is real, right-click GHub.exe in Task Manager, select Open file location, and confirm the path is C:\Program Files\LGHUB. If it is anywhere else, scan it with Windows Defender immediately.
Why does GHub.exe use so much CPU?
High CPU usage from GHub.exe is usually caused by a software loop, a stuck update process, or a conflict with another running application. End the task in Task Manager, relaunch G HUB, and monitor CPU usage again. If it stays high consistently, a clean reinstall usually resolves it.
Can I uninstall GHub.exe and still use my Logitech device?
Yes. Your Logitech mouse, keyboard, or headset will still function as a basic plug-and-play device without G HUB. You just lose access to custom DPI settings, RGB profiles, and macros. The hardware itself does not depend on the software to work.
GHub reinstalls but still does not work. What now?
If reinstalling does not fix it, the issue is almost certainly leftover files in AppData or a registry conflict. Go back to Method 3 and make sure you deleted both the %localappdata%\LGHUB and %programdata%\LGHUB folders before reinstalling. Also delete the registry keys listed in that section.
Does G HUB work on Windows 11?
Yes, G HUB is compatible with Windows 11. If you are having issues specifically after upgrading to Windows 11, try setting GHub.exe compatibility mode to Windows 10 and run it as administrator. A fresh install on Windows 11 also tends to work better than upgrading from a Windows 10 installation that already had G HUB.
