Windows 10 Insider Version 21H2 Build 19044.1499 ReviOS January 14 2022

ReviOS aspires to re-create what Windows as an operating system should have been - easy and simple.

With the main audience being gamers, power-users and enthusiasts, we understand that performance, speed and low latency is obligatory, which is why great effort has been invested into making ReviOS a capable, efficient yet private operating system.
Being naturally light on resources, footprint and size it also comes in as a great fit for low-end systems.

Performance
Windows 10 is notoriously known for its less-than-ideal performance, especially when compared to its predecessors.
ReviOS attempts to speed up the system, by eliminating redundant tasks and services running in the background, without sacrificing on stability.
Better yet, framerate stability is greatly improved, meaning your FPS is less prone to fluctuation.

Privacy
Microsoft's Windows 10 is infamous for its privacy-intrusive behaviour towards consumers, which is why ReviOS takes the privacy aspect into serious account.
A plethora of telemetry backdoors have been terminated including, but is not limited to: Asiimov (telemetry client), UWP/AppX Apps, Windows Update and Cortana.
Data collection and reporting increase the system load, and as a bonus, that too is severely reduced, hereby promoting performance.

Stability
Based on a multi-layered approach, securing retained and comprehensive stability.
Reinforcing performance and privacy by stripping out bloatware that halts the system, and cutting down on the amount of components - resulting in reduced OS size.
ReviOS attempts to enhance what can be enhanced, leaving the subjective things to the user. A reliable, yet flexible baseline to build upon.
Add, modify and extend to your heart's content.
