Bingo. All my experience is on Linux, and I've never written anything for Windows. So recently when I needed to port a small C program to Windows, I told ChatGPT "Hey, port this to Windows for me". I wouldn't trust the result, I'd rewrite it myself, but it let me find out which Win32 API functions I'd be calling, and why I'd be calling them, faster than searching MSDN would have done.
