Standard Windows 10 22H2, even when cleanly installed, consumes around 1.5–2 GB of RAM at idle and runs dozens of background processes. The Ultralight variant aims to slash that by 60–70%. Here is a comparison table:

| Feature | Stock Windows 10 22H2 | Windows 10 Ultralight 22H2 (19045.5198) | | :--- | :--- | :--- | | RAM usage (idle) | 1.8 – 2.2 GB | 500 – 800 MB | | Background processes | 120+ | 40 – 50 | | Windows Defender | Active (real-time) | Often removed or disabled | | Cortana | Present | Removed | | Microsoft Edge | Integrated (unremovable) | Removed or replaced | | Windows Store/UWP apps | Full suite | Stripped (only essential runtimes remain) | | Telemetry & data collection | Enabled (Basic/Enhanced) | Fully disabled | | Page file usage | ~2.5 GB | ~1 GB | | Disk footprint | ~20 GB (x64) | ~5 – 8 GB | We tested the 19045

The Ultralight build strips away components like Print Spooler (if not needed), Bluetooth support (optional), Windows Subsystem for Linux, Hyper-V, Fax and Scan, Media Player, Xbox services, and OneDrive. The result is an OS that feels snappy on as little as 1 GB of RAM and a 16 GB SSD.

This is the million-dollar question. By removing Defender, Windows Update, and Firewall components, an Ultralight build is technically less secure against network worms. However, it is more secure against privacy invasions and Microsoft's cloud features. The Ultralight variant aims to slash that by 60–70%

The philosophy behind this Ultralite build is simple: If you don't need it to run Windows, it goes.
