so thats why i get multiple instances of chrome in my processing window in my task manager? Seems like there's usually one per tab i have open

i have no idea how windows does anything but, abstractly, chrome runs as a process which itself spawns multiple threads per tab/whatever. a process is different than a thread (something a lot of people don’t know and get confused). the difference is kind of long-winded but you can google for an explanation of how they are different.
