This question already has an answer here:
How do I connect from a Win7 PC via local LAN to a Ubuntu Dektop 16.04.01 PC's command line window using only software that comes on the original installation DVDs?
Edit: Did a Full rephrase of the question, because answers so far showed that the question was not understood as I intended. This is not about anything I can download from the web an put to these machines somehow, e.g. SSH or anything. There are enough other answers that address those as linked in the first answer. So its not a duplicate. Its about can I achieve it with what is on the original DVD only. As its an ubuntu forum, answers may skip the windows side, of course.
