What ArcOS Actually Is
ArcOS is a Windows configuration framework — not a custom operating system. It applies a structured, reproducible set of configuration rules to a clean Windows installation.
The project focuses on reducing unnecessary background services, removing consumer-facing features, and applying supported system policies in a controlled and reversible way.
ArcOS does not redistribute Windows, modify system binaries, or patch the kernel. It operates within supported configuration boundaries.
ArcOS
Modular, deterministic, reversible.
- Manifest-driven engine execution
- Risk-tiered configuration profiles
- Windows build compatibility validation
- Rollback state tracking
- Deployment reporting
Architecture
ArcOS is built as a modular execution framework composed of isolated engines.
Modular Engines
Services, scheduled tasks, AppX packages, policies, performance tuning, and UI configuration are handled by independent engines.
Manifest-Driven Execution
Engine metadata defines risk level, compatibility, and reboot requirements. Playbooks determine execution order.
Deterministic
Configuration is idempotent and reproducible. Re-running ArcOS results in the same validated state.
Reversible
Restore points and state tracking are created prior to modification, enabling controlled rollback.
What ArcOS Does Not Do
- No custom Windows ISO
- No kernel patching
- No binary modification
- No Windows component redistribution
- No update servicing stack interference
Open Source & Transparent
ArcOS is open source and available under the GNU GPL-3.0 license. Review the engines, modify playbooks, or build your own profiles.
