Unreleased

1.0.0 - 2025-10-11

Added

Initial Release - The first stable release of WNU OS (Windows Not Unix) - a sophisticated Unix-like shell environment for Windows.

Core Shell Features

  • Complete Unix-style shell with authentic command-line interface
  • Getty-style login screen with tty1 terminal identification
  • Colored prompts - Green for normal users, plain text for root
  • Unix path display - Forward slashes and ~ home directory support
  • Hidden password input - True Unix-style authentication with no visual feedback

Authentication System

  • Multi-method authentication supporting multiple credential types
  • Windows Hello PIN integration with PowerShell verification
  • Smart credential detection - Automatic PIN vs password recognition
  • Fallback authentication - runas command and logon session validation
  • Enterprise security - Multiple Windows authentication API support
  • User privilege management - Root vs normal user modes with proper access control

Built-in Commands

  • Navigation: cd, pwd with Unix-style path conversion
  • File operations: Custom ls command with -a (show hidden) and -l (long format) flags
  • User management: whoami, su for user switching between root and normal user
  • System information: uname -a with proper architecture detection (x86_64, i686, arm, aarch64)
  • System control: shutdown, poweroff now, halt, reboot with interrupt handling
  • Utilities: clear/cls for screen clearing

System Management

  • Boot sequence simulation with detailed service startup progress
  • Graceful shutdown procedures with service stopping simulation
  • System halt with restart capability - Ctrl+S+H to restart shell from halt state
  • Reboot with interrupt support - Ctrl+C, ESC, or I key to cancel reboot
  • Real-time service status with Unix epoch timestamps
  • ANSI color support with loading bars and status indicators

Advanced Features

  • Interrupt handling - Multiple methods (Ctrl+S+H, Ctrl+C, R key) for emergency controls
  • Home directory management - Automatic path resolution and ~ substitution
  • Windows API integration - Native system calls for authentication and file operations
  • Process simulation - Realistic Unix-style system behavior on Windows
  • Error handling - Comprehensive error checking with helpful user feedback

Technical Implementation - Architecture

  • Native C implementation using Windows APIs
  • Modular design with separate components (boot, halt, poweroff, reboot, userlogin)
  • Memory safety with proper buffer management
  • Cross-compilation support for Windows environments

Technical Implementation - Build System

  • Makefile for Unix-style building
  • build.bat for Windows batch compilation
  • GitHub Actions CI/CD with Windows runner and MinGW toolchain
  • Artifact generation with automated build verification

Technical Implementation - Security Features

  • Multi-layer authentication with enterprise-grade security
  • Privilege separation between root and user contexts
  • Secure input handling with hidden credential entry
  • Windows security integration using native authentication APIs

User Experience - Interface Design

  • Authentic Unix feel with proper command syntax and behavior
  • Visual feedback with colored output and status indicators
  • Professional login experience matching traditional Unix systems
  • Consistent prompt design with hostname, username, and path display

User Experience - Compatibility

  • Windows 10/11 support with full API compatibility
  • MinGW/GCC compilation for native Windows executables
  • Terminal compatibility - Command Prompt, PowerShell, Windows Terminal
  • ANSI color support via Virtual Terminal Processing

Documentation - Project Files

  • Comprehensive README files at root and version levels
  • Security policy with vulnerability reporting procedures
  • Contributing guidelines with development standards
  • Code of Conduct for community participation
  • License under GNU General Public License v3

Documentation - Development Resources

  • Pull request templates with structured review process
  • Issue templates for bug reports and feature requests
  • GitHub workflows for continuous integration
  • Build instructions for multiple environments

Build and Installation - Compilation

# Using Make
make

# Using Windows batch script
build.bat

# Manual compilation
gcc -o wnuos.exe main.c boot.c halt.c poweroff.c reboot.c userlogin.c

Build and Installation - System Requirements

  • Operating System: Windows 10 or later
  • Compiler: GCC (MinGW recommended)
  • Terminal: ANSI color support recommended
  • Dependencies: Windows SDK, standard C libraries

Known Issues

  • Quote handling: Typing single quotes (') may cause continuation prompt - type closing quote or Ctrl+C to exit
  • External commands: Some Windows commands may behave differently than Unix equivalents
  • Path handling: Mixed path separators in some edge cases

Usage Examples

Basic Login and Navigation

# Login as root (no password required)
WNU OS 1.0.0 COMPUTER tty1

COMPUTER login: root
Welcome, root!

# Navigate and list files
root@COMPUTER:~# pwd
/
root@COMPUTER:~# ls -la
# Shows detailed file listing with colors

# Switch to normal user
root@COMPUTER:~# su username

Authentication with PIN/Password

# Login with Windows username
COMPUTER login: tadeo
Password: [hidden input - no visual feedback]
✓ PIN authentication successful
Welcome, tadeo!

tadeo@COMPUTER:~$ whoami
FULL USERNAME: COMPUTER/tadeo
USER'S HOME DIRECTORY: C:/Users/tadeo
USERNAME: tadeo
