Windows Update installs LG Monitor app with McAfee ads silently
Windows Update slipped LG Monitor App Installer onto a Windows 11 PC with no prompt, then pushed McAfee ads on nearly every boot.
A new LG UltraGear monitor connected to a Windows 11 PC triggered Windows Update to silently install LG driver updates and the LG Monitor App Installer, with no permission prompt or notification. The package then began surfacing McAfee promotions, turning a basic display setup into an unsolicited software install.
A Reddit post dated July 1, 2026 described a pop-up from “LG Monitor App Installer” after sign-in and stressed, “I literally do not have McAfee installed, this is a advertisement pop up from LG Monitor App Installer.” A Microsoft Tech Community thread dated July 9, 2025 raised the same complaint, saying Windows 10 and 11 were auto-installing “LG Monitor App Installer” and “LG Monitor Support Application Drivers,” and arguing the software should be “OPTIONAL AND INSTALLABLE BY THE USER NOT FORCED INSTALLED BY WINDOWS UPDATE.”
Gamers Nexus said the behavior happened on a Windows 11 test machine after an LG display was connected, and its video description said LG “recently forced upon us an app install loaded with McAfee adware through a Windows update.” Hardware Busters added a telling metric: Gamers Nexus booted the machine 32 times and saw a McAfee pitch on 31 of those starts. That repeat trigger makes the issue more than a one-time setup nuisance; it keeps returning the same commercial offer after each reboot.
The Microsoft Store listing says LG Monitor App Installer lets users “easily install and use apps supported by your monitor” and can be installed on up to ten Windows devices. LG support pages have long walked users through monitor driver installation and software such as Dual Controller, which places this install in the gray area between legitimate hardware support and software users never explicitly asked to receive. Community reactions have been blunt, with forum posters calling it a potentially unwanted program.
Gamers Nexus also tied the monitor case to earlier criticism of LG smart TVs and their microphone warning language, folding the episode into a broader fight over what counts as consent on modern PCs. When Windows Update can deliver both driver support and promotional software in the same flow, the user loses the clear line between maintenance, OEM partnership, and advertising.
