The reason you hear less about Window's OOM killer is simply because it works well.
The Linux Kernel OOM killer kills random things. Userspace OOM killers are meant to improve this, and they work well in a server situation when you already know in advance what is likely to go haywire and what is safe to kill. But they don't work well on desktop (some of them are improving but it doesn't seem to be a priority).
The Windows OOM killer by comparison usually kills something sensible (i.e. the program that is actually using all the memory), and asks the user for permission before killing it (when possible). You do see a lot of memes of situations where it fails.
Which, by default, is dumb for a presumably interactive system. Photoshop (or equiv) is going to be my "largest" process on a system. Because it's the one I'm interacting with.
You can always tell the system not to kill your Photoshop (or whatever else) by setting the OOM Score Adjust. This mechanism has existed for almost two decades and systemd has supported it for over a decade.
I think Windows doesn't do OOM kill, it just fails fast for unreasonably large memory allocations. If the allocation is succeeds, the committed virtual pages are backed up (or more precisely guaranteed to be backed up) by a page file.
damn, good observation, when my data analysis python script goes wrong and allocates 24 GB of RAM on a 32 GB computer, it crashes (gets killed) with "out of memory" error. I've never seen something else getting killed
