This custom ISO utilizes a aggressive component-stripping architecture to reduce the installation footprint by approximately . By completely removing non-essential system bloat—including Windows Defender, Cortana, Windows Update, Telemetry services, and all UWP pre-installed apps—the operating system achieves a fresh install size of under 2.5GB on disk with a running memory (RAM) usage as low as 400MB idle. This extreme leanness allows the OS to be fully functional on legacy hardware with limited resources, while the ISO itself remains compact enough (approx. 500MB) to fit on a standard CD-RW or low-capacity USB drive for rapid deployment.
