Well, we mostly use a program based on what i think is called microsoft business dynamic nav(its like a windows 97 looking program lol). Other than that, we use office programs and internet browsing. As i said earlier, the new pc i just bought slows down by just trying to open two windows at once, which imo is pretty unacceptable for a new computer. They didnt specify any specs for the hdd other than size so i will just build the pcs from now on.
