is a "Lite" or modified version of the Microsoft Windows 8.1 operating system. It is not an official release from Microsoft. Instead, it is created by third-party developers (often found on forums like TeamOS, GFXDomain, or various tech-sharing sites) who modify the original Windows installation files (ISO) to remove specific components and tweak system settings.
Xtreme LiteOS 8.1 is a highly optimized, modified version of Windows 8.1
Using third-party ISOs carries an inherent risk, as the source code of the modifications is rarely public, and you must trust the creator not to have included malicious scripts.
