Deterministic Windows deployment.
Without rebuilding the OS.
ArcOS applies a structured configuration layer on top of a clean Windows installation. It reduces unnecessary services, scheduled tasks, consumer features, and background components — while preserving system integrity and update compatibility.
Architecture
ArcOS is not a modified Windows build. It is a deployment framework composed of isolated execution engines operating on official Windows installations.
Modular Engines
Services, scheduled tasks, policies, AppX packages, UI configuration, and performance tuning operate as independent modules.
Manifest-Driven Execution
System behavior is defined by configuration manifests rather than hardcoded tweaks. Execution is reproducible and deterministic.
Reversible by Design
Restore points and state tracking are created before modification, enabling controlled rollback if required.
System Changes Applied
ArcOS applies targeted system-level adjustments using supported Windows configuration mechanisms.
Service Optimization
Disables telemetry, consumer services, Xbox components, and non-essential background services while preserving core system stability.
AppX Rationalization
Removes provisioned and installed consumer applications, retaining only required system frameworks.
Policy Enforcement
Applies privacy, background activity, and update behavior policies using supported registry and policy configurations.
UI & Resource Reduction
Reduces animation overhead, transparency effects, consumer prompts, and idle background activity.
What ArcOS Does Not Do
- No custom Windows ISO
- No kernel patching
- No binary modification
- No update blocking
- No redistribution of Windows components
Frequently Asked Questions
Does ArcOS replace Windows? ▾
No. ArcOS operates on top of an official Windows installation. It applies configuration changes without modifying system binaries.
Is Windows Update preserved? ▾
Yes. Security updates remain functional. ArcOS does not forcibly block feature updates.
Is ArcOS open source? ▾
Yes. All engines and configuration logic are publicly available on GitHub.
