Windows works great out of the box. However, a fresh installation also includes background services, telemetry, pre-installed apps, and scheduled tasks that continue running even if you never use them. These consume system resources such as CPU, RAM, disk, and network in the background.
At the same time, many settings that can improve performance, reduce latency, or provide a smoother experience are not enabled by default.
