Hi there,
Win10 is soon not supported. Tbh Linux have been on my radar since I started to break from the US big tech.
But how is security handled in Linux? Linux is pretty open-source, or am I not understanding it correctly. So how can I as a new user make sure to have the most secure machine as possible?
I don’t know where you got your information from, but your mental model on how and why things work the way they do in both linux and windows seems to be really off.
Since you seem someone that is actually interested in understanding this stuff, I strongly suggest to find some better sources as your base
