I am not totally sure, I have to turn core isolation on on windows 10 to start with vanguard. I think it had problems, I am not even sure anymore. However, I know that I did not want to have a software running, that goes deep into the windows core to see what I am doing, as I want to keep my things to myself. No cheating though, that is for sure. I play Aram cuz it is fun and it is the most played game between me and my friends.
I believe the biggest thing was turning off vanguard again by restarting Windows. I would need to close my tabs, save my projects etc, when switching to Vanguard started Windows and then restart again when switching back. I might as well leave Windows altogether to games and switch to linux otherwise. I am already halfway there.
Why Vanguard is bad for me as a Software Developer
