Games

Plenty of games use it, if it uninstalled with each one then others would stop working.

Do you remember when Sony released cds that when inserted into Windows computer auto ran an installer that installed a rootkit that made it impossible for Windows to see any processes or files that started with a certain sequence of characters instantly turning any malware that named its files or processes similarly powerful rootkit. Oh and it installed a cd driver that made it impossible to copy their music.

Suggested removal was a full reinstall of windows.

Oh it was initially classed as insanely intrusive malware when kernel level AC was introduced about a decade ago, by anyone with a modicum of actual technical knowledge about computers.

Unfortunately, a whole lot of corpo shills ran propaganda explaining how actually its fine, don't worry, its actually the best way to stop cheaters!

Then the vast, vast majority of idiot gamers believed that, or threw their hands up and went oh well its the new norm, trying to fight it is futile and actually if you are against this that means you are some kind of paranoid privacy freak who hates other people having fun.

I've been shouting from the rooftops for years that this stuff is malware. I'm not the only one. No one listens.

EAC installation process includes "registration" of a game, and the uninstall process "unregisters" the game. If all games using EAC are uninstalled, EAC itself also should be uninstalled.
