On Windows 11 24H2, more stack space was modified by a new implementation of Critical Sections.

IMHO this shows the downfall of Microsoft. Why did they do that? Critical sections have been there for many decades and should be basically bug-free by now. My best guess is someone thought they'd "improve" things and rewrote it, then made some microbenchmark that maybe showed the dubious improvement.

The other comment here mentions Raymond Chen, who wrote this article about why backwards-compatibility is very important (and arguably what got Microsoft into the position it's in today):
