AG6 window 10 installed in French.... how can i change to English or other language

recently i purchased predator AG6 from bestbuy and on their site operating system in English however when i start computer at the first time, window 10 set up shows up in French (Canada).... so i tried to choose other language however there were no English nor my mother toung on the list. so i guessed everything to start up and succesfully chaged to display language.

but still i have a major problem.

window operation language is in French.

when i was updating windows, it shows me in French. i have no idea what it says. even I try to reset to factauly defalut but all French.... i do format like every 6 month to keep the system clean.
