Installing Windows 10 is no easy task, it would also require to buy a licence.
When I say "not helping", it's because your claims are without foundation and actually mostly false:
Deadfire support is not end of life, they have contacted me to solve the issue. Besides, those forums are still here, aren't they?
Windows 7 is not officially supported by Microsoft, except for a fee
the fact Windows 7 reached its end of support doesn't mean software running on it is not supported anymore
driver age is relevant, it's the first thing any support will ask you to update (and what has been asked in this case too). Why? Because new drivers either solve issues present in older ones, improve the features, or improve the compatibility with the recent OS updates. Keeping old versions is asking for trouble most of the time. You seem to contradict yourself on that topic, by the way.
So please just stop trying to help because you just achieve the opposite. Your intention may be good, but guessing and repeating hearsay is usually the worst idea when trying to solve a technical issue.
