Windows X-Lite Optimum 10 Pro v5.1 is a lightweight, modified version of Windows 10 Pro (typically based on the 22H2 or 21H2 builds). It is designed to run on systems with as little as 2GB of RAM and a dual-core processor, yet it remains fully functional for daily tasks, gaming, and even light content creation.
One of the biggest selling points of v5.1 is its ability to run on ancient hardware.

Note: This build works exceptionally well on tablets, netbooks, and laptops from 2010–2015.
Bottom line: Performance improvements look impressive on paper, but the trade-off in security and stability makes it unsuitable for everyday use unless you’re an advanced user in an isolated environment.
