No part of the Windows syscall ABI is stable on Windows. Not win32k, not core NTAPI. You need core NTAPI to send IPC messages.

- AstralStorm 9y agoIt is stable in the terms of "actually didn't change in a way to break apps" not "guaranteed to be kept compatible". Last time they did a major break there is in Windows 2000. I recommend reading up on how LPC works. There have been extensions though. Such as very useful pico processes in Windows 10... Major extensions in Vista too, related to security and async operation. I recommend j00ru's blog as a good starting point. And of course Windows Internals books.
