Why Windows 11 still ships with Windows 95's memory manager hidden inside it (windowslatest.com)

I don’t know much about CPU and memory back then, but did they not have some kind of memory access debugging mode where it would match every access against the alloc map, understanding that it could be very slow, but would find some of this kind of bug? Come to think of it, do we even have that today?

I wouldn't be surprised by windows components that use this. Wish I could run 16-bit apps tho.

What else could be expected of Redmond's finest?
