How does Windows support inter-process communication using inter-thread communication mechanisms?

[ProfRon]

You ever wonder how apps on your Windows machine swap info without crashing into each other? I mean, processes are like separate crews working on the same ship. They need to pass notes somehow. Windows sneaks in tricks borrowed from how threads inside one process whisper to each other. Threads share memory like roommates splitting a pizza. No big hassle there. But for processes, it's trickier. They live in their own bubbles. Windows sets up named pipes for them to funnel messages back and forth. It's like threading a needle across rooms. You create a pipe with a name everyone recognizes. Then one process pours data in. The other slurps it out. Smooth as butter. Or take events. Threads flip a switch to signal they're done. Windows names those switches so processes can watch for the flip too. You wait on it. Boom, notification hits. No polling nonsense. Mutexes lock doors the same way. Name one, and processes take turns grabbing the key. Prevents everyone piling in at once. I love how Windows blurs those lines. Makes the whole system feel less clunky. Shared memory sections do the heavy lifting too. You map a chunk of RAM with a name. Processes peek inside like flipping through a shared notebook. Scribble updates. Read replies. Just watch for races, though. Use semaphores to pace it. Windows wraps all this in APIs that feel familiar if you've tinkered with threads. No reinventing wheels. Processes hum along, chatting without the drama.
