I need to know if possible where i can find a few images like the close, maximize and minimize buttons for the windows are i have been looking for 20 mins to no avail

i have found most thing that i am going to change but as i am new to this and enjoying it plaese can someone maybe give me a list of where all the common item locations are like the taskbar 1166 and 921.

as i say i am pretty new to this so if im missing something help me out please
