- Summary: Reports on 2026-07-18 documented that connecting certain LG monitors to a Windows PC makes Windows Update install LG's "LG Monitor App Installer" (Microsoft Store package
9PM9N6F47JB8-LGElectronics.LGMonitorApp) and related utilities such as OnScreen Control, LG Switch, Dual Controller, and UltraGear Control Center with no consent prompt. The install path is the Windows "Hardware-First Installation" flow, where a Device Metadata Retrieval Client matches connected hardware against Microsoft-hosted metadata and pulls the associated Store app automatically. Users reported a McAfee subscription advertisement appearing after the install, although McAfee itself was not installed. Blocking the behavior requires the Group Policy setting "Prevent device metadata retrieval from the Internet" or the PreventDeviceMetadataFromNetwork registry value, which disables all device metadata retrieval. - Comments: HN commenters report the same channel delivers vendor packages from other manufacturers whose drivers ship through Windows Update, citing Razer, Logitech, and Nvidia, and note there is no per-device "driver only" option. Several point to the Device Installation Settings Group Policy toggle as the workaround.
- Why it matters: Windows Update is acting as an unconsented software-distribution channel for vendor apps and third-party promotions, which is a platform-trust and endpoint-management concern for anyone provisioning Windows machines.
- Follow-up: Watch for an LG or Microsoft statement and whether the automatic install scope narrows.
