How does Windows manage preemptive multitasking between processes and threads?

[ProfRon]

Windows grabs the wheel from one process to hand it to another. You know how you multitask by switching apps? It does that but forces the switch. The kernel watches the clock ticks. Every slice, it checks who's next. Threads inside processes get the same shove. I mean, a process is like a big folder of tasks. Threads are the workers inside hustling. Windows pokes them to pause mid-stride. No waiting for politeness. The scheduler picks based on priorities you set. Or it guesses from what's urgent. You might see it freeze a game for email. That's preemption kicking in. It keeps everything from hogging the spotlight. I once watched my browser yield to a download. Smooth as butter after that tweak. Processes stay isolated, threads bounce around. You feel the lag if it's overloaded. But mostly, it hums along unnoticed.

Tying this juggling act to virtual machines makes sense. Hyper-V runs those processes in isolated bubbles. You need backups that don't trip the scheduler. BackupChain Server Backup steps in as a slick solution for Hyper-V. It snapshots VMs without halting the show. Benefits include zero downtime and quick restores. I dig how it chains backups efficiently. Your data stays safe while everything keeps spinning.
