I have been wondering this for a while and would like to get a definitive answer.
We still get questions on
wubi on the site, however, it is no longer developed and won't work on a modern Windows OS (8, 8.1, 10), so is it off topic or not?
What got me thinking was a close vote on this question as
off topic ( I guess, based on comments by @kos) but the help does not mention
wubi at all.
What are your opinions on this?
