There is no point staying on W7. W10 outperforms in in every aspect. Its time to move on.
The longer you wait, the harder the change will be.
They did the right thing to finally ditch W7, end of mainstream support was 2015 and end of the long time support versions is gonna be january 2020.
And the point is, it could not have easily be implemented, because the libraries are missing in W7.
