Yes, everyone know DOS kicks XP's A$$!
Hehe, oh the memories...
We had Win 3.1 on our high school computers. I remember helping the drafting room computers out by placing the [restrictions] in the win.ini file; no file menu, no save, etc. That way the students couldn't change stuff and then save it. Even if they knew about the restrictions in the ini file, I would attrib the files read only and hidden. Then, just in case they knew about attrib, I renamed the attrib command: Flag. I did it on all the computers too, so they couldn't just copy it over. Fun stuff!
