> the Win32 personality is the only one of the original personalities for which this is true The entire personalities thing was pretty much never used. I could never run anything OS/2 except for a couple 16-bit command line utilities, and the POSIX one was straight garbage and likely the source of many Weirdnix contest stories. It was only until Interix that you could actually source port anything worthwhile, and they quickly hit the limit that the POSIX and Win32 personalities could not speak to each other with anything other than TCP/IP. WSL1 quickly dropped the POSIX personality and switched to the Drawbridge sandbox stuff (in part to be able to access the Win32 subsystem, and to be able to skip PE binaries), and WSL2 followed by dropping the entire idea and using a then more classic HVM.
