Plugging an LG monitor into a Windows PC was enough to trigger McAfee advertisements for some users — until Microsoft stepped in.
The event centered on LG’s Monitor App Installer, a companion application that is automatically distributed to compatible Windows PCs via Microsoft’s Hardware Support App framework. Over the past weeks, many Windows users complained that LG’s software was installed automatically and displayed recurring McAfee advertisements.
Microsoft responded after the issue gained traction, with Windows chief Pavan Davuluri confirming in an X post that LG would disable the advertisements. The move removes the pop-ups but has left many users asking questions around privacy, trust, and consent.
How a Windows feature became an advertising channel
Windows’ Hardware Support App (HSA) rarely attracts much attention. HSA is designed to automatically deliver companion software for supported hardware connected to a Windows device. In the case of LG monitors, the system quietly installs applications that help users manage the connection between both devices, update firmware, and unlock additional features provided by LG.
That changed when Windows users with LG monitors began noticing recurring McAfee advertisements generated by LG’s companion software.
The ads originated from the LG Monitor App Installer, which users reported was installed automatically through Windows’ device-software delivery system. According to Gizmodo, the app was delivered through Microsoft’s Windows distribution infrastructure, which can automatically install companion applications for supported hardware.
The Windows update itself was routine, automatically delivering the drivers needed to support compatible LG monitors. The controversy centered on LG’s Monitor App Installer, which arrived through that process and then displayed recurring McAfee promotional pop-ups, prompting users to question why companion software was being used as a marketing channel.

Microsoft draws the line on OEM advertising
Online criticism intensified and soon reached Microsoft’s leadership after Epic Games founder and CEO Tim Sweeney publicly tagged Windows chief Pavan Davuluri in an X post highlighting the complaints. Davuluri acknowledged the reports, saying Microsoft was looking into the matter.
Three days later, Davuluri returned with an update, confirming that Microsoft had contacted LG about the issue. According to him, LG agreed to disable the McAfee advertisements.
LG, however, defended how the software was delivered. The company maintained that users have the option to download the app, which it says is delivered through Microsoft’s official Windows distribution process.
The company also added that the Monitor App Installer does not collect or transmit users’ personal information.
What this means for Windows users
For most users, the immediate annoyance should disappear once LG removes the McAfee pop-up. The broader question, however, is whether hardware makers should be allowed to use Windows’ companion app system to deliver software and promotional content without a more explicit opt-in. Microsoft’s response suggests it is willing to intervene when partner behavior harms the Windows experience.
For a company long known for bloatware and ads, that action could also be a way to further prove to customers that Microsoft is indeed trying to give users back control while making a cleaner Windows experience, even when adware comes from third-party integrations.
From another lens, it highlights growing expectations that platform owners take responsibility for third-party software distributed through their ecosystems. Platforms, like Microsoft, which owns the underlying architecture, are increasingly being asked to share responsibility for things that go south in their pipelines.
