it indeed ansmer my question about wget but not the rest
My advice would be not to ask two questions in one, which is the case with your original post.
Users frequently don't ask about the real issues they are having, but rather about the problems they encounter with the solution they think is right. This is the XY problem. In your case, your question
Is there a way to install a soft using only cmd.exe (shell) on windows XP?
lacks a bit of context. It's not clear why you'd need to know, or what you really need to accomplish. We require questions to be based on an actual problem you're facing, but it was not apparent what that was.
However, you gave us another question right after that, asking for the equivalent of
wget in Windows. That is something we can work with, and it so happens that we already had a question that covered it.
I suggest that in your case, you ask a new question about installing software using the command line, and tell us why you'd need to know and what you need to achieve. That way you'll get better answers. Or, you edit your existing question to remove the part about
wget and flag it for attention to have it reopened.
