Riot Games is making a big change to its Vanguard anti-cheat system: After an update set to go live today (and which may already be live by the time you read this) it will not launch when your PC boots up, but will instead will be "on demand," meaning it will only run when playing a game and will shut down once the gameplay is over.
Vanguard was very controversial when it launched in 2020 because it's "kernel mode" software that, in theory at least, grants Riot access to your PC at an alarmingly deep level. On top of that intrusiveness, it's also effectively omnipresent: It launches when your PC does, and it runs quietly in the background, doing whatever, until you shut down.
