Yes, Windows doesn't overcommit memory. In the default config Windows is allowed to grow the page file as much as it wants, and empty pages are cheap to reserve in the page file (no need to actually write those zeros, you just need to reserve space for them). So the end effect is comparable, with the difference that software shouldn't just go ahead and ask for gigabytes of memory it doesn't actually need

I prefer the Windows approach, it's more predictable and has better behavior under memory pressure. But it can cause issues with software written under the assumption that the OS uses memory overcommit
