A Windows update reportedly triggered the silent installation of an LG-branded application on user systems, which then displayed an unsolicited McAfee promotional pop-up even on machines where McAfee was never installed. <\/p>\n
The issue surfaced after a Reddit user in the r\/pcmasterrace community documented the incident, tracing the software back to the Microsoft Store and Windows Update mechanism.<\/p>\n
The user, who owns three LG UltraGear monitors (one 27GP83B and two 27GN800 units), discovered that connecting the displays caused Windows to automatically match device metadata to a Microsoft Store listing and download the corresponding application without any notification. <\/p>\n
Windows Update Allegedly Installs LG Monitor App<\/p>\n
The app, identified in Reliability Monitor logs as \u201c9PM9N6F47JB8-LGElectronics.LGMonitorApp,\u201d was confirmed installed via Event Viewer records showing a \u201cSuccessful Windows Update\u201d entry.<\/p>\n
Checking Task Manager\u2019s startup apps confirmed the LG Monitor App Installer had been added automatically to the PC without user consent.<\/p>\n

Shortly after installation, the app displayed a pop-up labeled as McAfee, urging users to start a \u201cfree 30-day trial\u201d of McAfee\u2019s Scam Detector feature. This caught users off guard since many had never installed any McAfee product on their systems.<\/p>\n
Security researchers and outlets covering the report noted that this is not an isolated case tied solely to LG hardware. <\/p>\n
Similar silent-install behavior has reportedly been observed with Alienware<\/a> and Asus monitor companion apps, suggesting the underlying mechanism Windows\u2019 Device Setup Manager pulling OEM-linked apps via device metadata is a broader systemic issue rather than an LG-specific bug. <\/p>\n Microsoft\u2019s own tech community forums show user complaints about the LG Monitor App dating back to at least November 2024, indicating this behavior has persisted across multiple Windows builds.<\/p>\n Mags_Smash stated that<\/a> the LG Monitor App Installer cannot be removed through the standard Microsoft Store uninstall path. <\/p>\n The only confirmed workaround for casual users is disabling the app from launching at startup via Settings > Apps > Startup, which stops the pop-up without fully removing the underlying package.<\/p>\n Mitigation<\/p>\n For users seeking a permanent fix, two Group Policy-based solutions have been documented:<\/p>\n Block metadata-triggered installs: Enable \u201cPrevent automatic download of applications associated with device metadata\u201d under gpedit.msc > Computer Configuration > Administrative Templates > System > Device Installation.<\/p>\n Disable the Microsoft Store entirely: Navigate to gpedit.msc > Computer Configuration > Administrative Templates > Windows Components > Store, and enable \u201cTurn off the Store application\u201d.<\/p>\n The first option is the more targeted fix, as it specifically stops Windows from pulling manufacturer-linked apps tied to connected hardware, while preserving normal Store functionality. <\/p>\n Windows Home Edition users who lack access to gpedit.msc can instead adjust manufacturer app download settings directly in System Properties under Device Installation Settings. <\/p>\n Microsoft has not issued an official statement addressing the reports as of this writing, and it remains unclear whether the company plans to alter the device-metadata download mechanism responsible for the unsolicited installs.<\/p>\n Follow us on\u00a0Google News<\/a>\u00a0,\u00a0LinkedIn<\/a>\u00a0and\u00a0X<\/a>\u00a0to Get More Instant Updates.\u00a0Set Cyberpress as a Preferred Source in\u00a0Google<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"A Windows update reportedly triggered the silent installation of an LG-branded application on user systems, which then displayed…\n","protected":false},"author":2,"featured_media":80272,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[621],"tags":[5033,10454,315,357],"class_list":["post-80271","post","type-post","status-publish","format-standard","has-post-thumbnail","category-lg-electronics","tag-cyber-security","tag-cyber-security-news","tag-lg","tag-lg-electronics"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/80271","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/comments?post=80271"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/80271\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media\/80272"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media?parent=80271"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/categories?post=80271"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/tags?post=80271"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}gpedit.msc (Source: r\/pcmasterrace )<\/p>\n
