Can i run guild wars 2 in a windowed mode ?

Hello guys, i was curious if i could run guild wars 2 in a windowed mode. I plan to play stream raiders, and watch twitch, and i know that combine work load is going to impact my CPU and memory. I am ok with that.

So can i run guild wars in windowed mode, and if so, any advice you can give me or should i lower the FPS and graphics ?

i haven't tried it yet but i plan to get back into guild wars 2 very soon.

Thanks all and i like to hear any mechanical input. Thank you <3

Windowed Mode is one of the options found in-game.
