my QUESTION is if I connect two computers together to to use internet connection (shared) does the other computer have access to my files and programs?  and if so how do I keep the other computer from using or seeing my files I don't want him to see?  in other words if I connect two computers together to use same internet connection can the other computer see my files on my computer and can he change my settings, I don't what the other computer to use or see my files but want them to share the same internet conection.The other computer will have access to files that you are sharing. ok is there a way to keep the other person that is sharing the internet from seeing/ using my files?Yes, don't share any files. I don't have windows 7 but it hasn't changed much from vista. If you go to "network & sharing" in the control panel you should see options in the BOTTOM for "file sharing" & "network discovery". They each have a quick description of what they are. READ them & after you understand them turn them off. THANKS I think that is what I need to do appreciate the help!
