How does Windows manage thread synchronization across multiple cores or processors?

[ProfRon]

You ever wonder why your apps don't crash when they juggle tasks on different cores? Windows keeps threads in check with sneaky handshakes. Threads grab shared stuff like memory chunks. They wait their turn using locks that flip on and off. I mean, one thread snags the lock first. Others chill until it lets go. That stops the chaos of everyone scribbling at once. Cores zip along independently. But Windows syncs them through the kernel's watchful eye. It dispatches signals quick as a wink. You see, without that, data turns to mush. Threads signal each other with events too. Like a nudge saying, "Your move now." Windows juggles these across processors smoothly. It balances the load so no core idles. Pretty slick how it prevents pile-ups. Threads might spin in loops waiting. But the system wakes them sharp. You get smooth multitasking that way. No big drama behind the scenes.
