How does Windows Update handle the installation of patches service packs and cumulative updates?

[ProfRon]

You ever wonder why your PC sometimes nags you to restart? Windows Update grabs those patches quietly in the background. It checks online for fresh ones whenever you boot up or connect. Patches fix little glitches fast. I like how it bundles them without you lifting a finger.

Service packs come in bigger waves. They pack a bunch of fixes together. Windows Update downloads the whole chunk at once. You might see a progress bar crawl along. I remember one that took forever on my old laptop. It restarts everything to make sure it sticks.

Cumulative updates roll up everything recent. They skip the old stuff you've already got. Windows Update scans your system first. It only pulls what you need. You get a notification when it's ready. I always hit pause if I'm in the middle of something.

It handles all this automatically most days. You can tweak settings if you want control. Patches slip in during idle time. Service packs demand more attention. Cumulative ones keep things tidy. I bet you've ignored a few prompts yourself.
