Without root/admin access, on windows programs can’t write in several important folders. By root user they meant program files, system 32 and all those “system files”, which, surprise, are root files.

A hacked kernel level program can modify system files and set up a keylogger that doesn’t even register on the program monitor, and it can send your information and you wouldn’t even notice it without monitoring your outbound packets, so you won’t.

Any other program would ask you admin/root access and if that’s weird behaviour you can deny it and investigate, kernel level programs have it by default so if they have an exploitable vulnerability, you are fucked by default. It’s a huge difference and the fact that you are not acknowledging it makes me feel like you really don’t understand how code works.

Also, don’t put riot and valve in the same bag. PLEASE.
