I've used an LG monitor for about 5 years, and never install the manufacturer's software unless it looks genuinely useful. When I saw the Gamers Nexus video I went to check my installed apps, and sure enough there was LG's monitor app, installed silently without my knowledge. I used Bulk Crap Uninstaller to get rid of it.
To prevent this kind of thing in future, run gpedit.msc and enable “Prevent automatic download of applications associated with device metadata” under Computer Configuration → Administrative Templates → System → Device Installation.

















Indeed. I use Linux most of the time, and MacOS a bit of the time, but the old Windows desktop is still there for the infrequent times when I need it to work on old music projects. I have it too dual-booting into Linux, so even it spends most of its time in a more sane OS.
