> Also Windows should step in and say that this application is consuming almos all of the remaining memory

This is much more complicated that it appears, because the user could be intentionally doing that - if you have little memory (8 GB), you are sort of always almost out of it, if you have a lot but you are using professional apps like Photoshop, video editing, or doing machine learning with large datasets.

I'm sure that the reason Windows doesn't do this is because they couldn't figure out a good way to warn which is also not annoying.

There are some Windows warnings, I've seen them, but they only appear when the situation is so dire the computer is about to blue screen.

I disabled the swap in Windows, because I have 32G RAM (and why put unnecessary wear on the SSD). And now it runs out of memory while half the RAM is empty.

A marvelous operating system.

But yeah, at least I saw the warning fast, with the swap file it first came to a sudden halt, and after a lot of time it might have shown the alert.

Turning off swap will lead to running out of memory earlier than you’d think because different tasks can allocate a lot instantaneously - you just need a few of them to line up and try allocating a lot at once.

I don’t see how you can realistically operate a computer this way unless you control all the software on it, or you enjoy buying way more RAM than you need.

(Also swap isn’t the only alternative to allocating memory - there’s also purgeable allocations and memory compression.)
