can anyone here tell me which brand makes 19 inch screens, provides a cd tray play and/or burner, usb ports for a mouse and/or keyboaed, vga in and out for a larger screen if a 19 inch screen is not available, and if a wifi adapter is built in. this is for someone else she is not tech savvy. I need something that is is easy for her to use. her desktop is win 7. a new one would probably be win 10. would it make sense to use my win 7 iso cd to install that? if yes is win 10 replaces or does both appear? if yes does a selection screen appear asking which OS she wishes to use? can she select one or the other? any advice welcome.
