By aggressively removing telemetry, background services, and native bloatware, the system frees up vital system resources like RAM and CPU cycles.
The defining characteristic of "Xtreme LiteOS" is the aggressive removal of Windows components. Unlike a standard installation, which can occupy 20GB+ and run numerous background processes, this build typically removes:
Because deep system files are ripped out, these builds frequently suffer from driver instability. Users often report that wireless drivers, print spoolers, virtual machine tools, or specific anti-cheat software for games (like Riot Vanguard) fail to install or cause immediate system crashes.
