I think you should group the questions to reflect the Who, Where, When, What, How, Why groups of questions. Like when you talk about installation process ("meet any issue", etc) group, add "Which OS do you use?" with that set of questions. In my opinion the most important questions are: Questions like: can be find out from the download page statistics. Also depending on the user he might not know exactly and even don't care. Questions like: find out the same answer (if is for me is on my pc, other on a server) You could do: - a first part with "mandatory" questions that really need answering (not very many), like satisfaction (with short answers 1-5 - very condense), suggestion, etc. - and another set of questions in the end with stuff that would be nice to know (like OS, period of time, version) - that may take too much time for the user to answer and only a true devoted person would answer them.
