Overview
- Monday testing by Gamers Nexus and multiple outlets showed Windows Update still auto-downloading LG driver packages and then installing the “LG Monitor App Installer” roughly a minute later with no separate consent prompt.
- The installer repeatedly displayed McAfee promotional pop-ups on boot during replicated tests, with a reported 30-day trial that can convert to a paid subscription.
- The Microsoft Store listing grants the installer runFullTrust rights so it runs outside the AppContainer sandbox and can access the internet and broad system resources while linking to an LG privacy policy that says device and usage data may be collected.
- Windows Pro and Enterprise users can block device-associated app installs using a Group Policy setting or remove the app manually but Windows Home lacks an easy built-in block, and neither LG nor Microsoft had issued a public fix or explanation at publication.
- This behavior stems from a Windows feature that lets vendors pair Store apps with device metadata to deliver companion software automatically, a mechanism also used by vendors like Dell and criticized for allowing unrequested bloatware and advertising on PCs.
