Some customers participating in the Windows 10 Insider Program may have upgraded to the Windows 10 20H1 preview build and encountered an issue where the Logitech G logo loops when attempting to run Logitech G HUB.

Affected customers have the following two options to recover:

Option 1:
Run the registry patch LGHUBUpdaterService and reboot the computer.

Option 2:
Uninstall and reinstall G HUB using the following instructions. 

NOTE: Please start by creating a backup of your G HUB settings if you wish to retain them. 

1. To back up your G HUB settings, navigate to C:\Users[USERNAME]\AppData\Local\LGHUB, where [USERNAME] will be specific to your Windows account.
2. Find settings.db and create a copy of it on your desktop or a different location of your choosing.
3. After backing up your settings.db file, open Task Manager and make sure there aren't any Logitech G HUB processes running. You'll need to end task on each of them before going further:
   1. In your taskbar, right-click on Logitech G HUB and select Exit.
   2. Open Task Manager and look for running Logitech G HUB processes. If there are running processes, right-click and select End task for each one.
4. Uninstall G HUB using Windows (Add or Remove Programs).

IMPORTANT: Did you backup your settings.db file? This is your last chance.

After confirming there are no G HUB processes running, do the following:

1. Navigate to C:\Program Files\ and delete the LGHUB folder.
2. Navigate to C:\ProgramData\ and delete the LGHUB folder.
3. Navigate to C:\Users<user name>\AppData\Local\ and delete the LGHUB folder.
4. Navigate to C:\Users<user name>\AppData\Roaming\ and delete the LGHUB folder.
5. Reboot.
6. Download and reinstall G HUB.
