LG’s McAfee adware proves why Microsoft needs to assume the worst of companies and protect Windows 11

LG got caught with its hand in the cookie jar this week. An investigation by Gamers Nexus revealed that plugging certain LG monitors into a Windows 11 PC silently installed a companion app without user consent.

Normally, some people would be OK with this, though others would argue that nothing should be able to install an app on your PC without permission.

But the situation escalated when it was revealed that the monitor app also showed ads for McAfee.

Microsoft was forced to step in. The tech giant reached out to LG and the McAfee ads no longer appear. But Microsoft should not have had to do anything at all. LG demonstrated that Microsoft needs to rein in accessory makers and get a tighter grip on Windows 11.

While the LG scandal dominated the headlines, we also saw major Xbox news and some Windows 11 upgrades.

Xbox brings back compat to PC, and upgrades OG Xbox games

Conker, Crimson Skies, Fuzion Frenzy, and Blinx head to Xbox PC for the first time, soon with Xbox achievements, and more are on the way.

One could argue that no company should be able to install software on your PC without explicit permission. But in a perfect world, those same companies could be trusted to only install relevant software such as a required monitor app or the drivers needed to make an accessory work.

Unfortunately, that’s not the case. LG abused the trust given by Microsoft and Windows 11 users by installing adware on people’s PCs whenever they plugged in certain monitors.

Microsoft needs to restrict these types of installs on Windows 11 and ensure that any app being installed is done so after a user has given permission. Even useful apps that help control a device should only appear when cleared by a user.
