https://learn.microsoft.com/en-us/windows/win32/sbscs/applic... has the majority here.

I don't see why you'd need a separate flag for memory management, Windows version, printer driver isolation, awareness of long paths, and all of that jazz.

Still, https://learn.microsoft.com/en-us/windows/win32/sbscs/applic... has a setting to enable modern memory management.
