Win11Debloat can now block LG from installing unwanted software

Windows has this interesting feature that enables OEMs to push software to user devices. This installs the apps automatically on unmanaged devices and supposedly helps get the most out of certain devices, such as monitors or printers.

While that sounds useful in theory, this feature has been abused in the past. The most recent example is LG installing its Monitor App on Windows PCs and using it to display advertisement for McAfee products.

Since this is unwanted by the vast majority of users, it is fair to say that this falls into the misuse of power category.

You can use Win11Debloat, a popular Windows tweaker, to get rid of the app and block LG from installing it again. Or, you could do it manually.

Here are the steps:

Remove the existing LG Monitor App

Because this is packaged as a standard modern Windows app, it can be uninstalled normally without needing to scrub your registry:

1. Open Windows Settings (Win + I).
2. Navigate to Apps > Installed apps.
3. Search for LG Monitor App Installer (or just “LG”).
4. Click the three dots (…) next to it and select Uninstall.

Prevent Windows from Auto-Installing Device Apps

Windows automatically downloads these OEM companion apps using a feature called “Device Metadata Retrieval.” You can disable this natively in the GUI:

1. Open System Properties: Press Win + R, type sysdm.cpl, and press Enter.
2. Navigate to Device Installation Settings:Select the Hardware tab, then click the Device Installation Settings button.
3. Disable Automatic Downloads:This stops all manufacturer companion apps.Select “No” (your device might not work as expected).
4. Save Changes:Click Save Changes and restart your PC.

Note that you can also make the change in the Registry or using the Group Policy.

Registry:

1. Press Win + R, type regedit, and press Enter.
2. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Device Metadata
3. Find the DWORD named PreventDeviceMetadataFromNetwork. If it’s missing, right-click an empty space > New > DWORD (32-bit) Value and name it exactly that.
4. Double-click the key and change its Value data from 0 to 1. Click OK and restart your computer.

Group Policy:

1. Press Win + R, type gpedit.msc, and press Enter.
2. Navigate to: Computer Configuration > Administrative Templates > System > Device Installation.
3. Double-click Prevent device metadata retrieval from the Internet (or Prevent automatic download of applications associated with metadata, depending on your exact Windows build).
4. Set it to Enabled, click Apply, and restart.

Here is the effect

By disabling this feature, you are shutting the door on all OEMs. This blocks automatic, silent installations of software from ASUS (Armoury Crate), Razer (Razer Synapse), Dell (Alienware Command Center), HP, Logitech, and others.

Importantly, this will not break your hardware. Windows will still automatically load the basic, essential drivers required to make the device function.

Disabling this setting only stops the automatic background installations triggered by Windows. You retain complete control to install whatever you want, whenever you want.

If you decide you actually need an OEM companion app—for example, to configure mouse macros, change RGB lighting, or update hardware firmware—you can easily bypass the restriction manually:

• Download directly from the manufacturer: Go to the official support page for your specific hardware (e.g., LG or Razer’s website) and download the driver package or software suite yourself.
• Install via the Microsoft Store: Many of these OEM control panels are hosted on the Microsoft Store. You can simply search for the app by name and click install.

Turning off automatic metadata retrieval is highly recommended for keeping a clean OS. It shifts control from Windows back to you, ensuring you only install the companion apps you actually plan to use.
