There's the rather famous AARD Code (https://en.wikipedia.org/wiki/AARD_code), though that is from an era a little before Win32. And, well, it's not a documentation issue for app developers, as much a way to trick OS developers.
LOL @ those memos. This was long before all our companies adopted the "Don't say anything in E-mail that could become evidence" training. Their ruthlessness and obsession with destroying everything not-Microsoft was truly unique and special. I can't think of any company here in modern times so focused on not only winning but making sure absolutely everyone else lost. Old-school Microsoft was wild.
