Hi - is this likely to be applied to an upcoming release? / How does a novice apply a patch..?
At this moment is missing review, so it is probably far from being commitable. Any attention is appreciated and might help pushing it forward. As a personal note, I have to check that is still applies before the upcoming commitfest.
As for applying this patch you would need a Windows development environment. I would recommend Visual Studio as a starting point [1]. You also have a very visual guide in the wiki [2].
