What Changed:

• Standard headers with figure/recipe reference, chapter title, and book attribution
• Platform notes indicating Windows-only features and prerequisites
• Section dividers with clear visual separation for logical groupings
• Educational inline comments explaining why commands work, not just what they do
• Expected output comment blocks showing what readers should expect
• Cleanup sections for scripts that modify system state

Chapters enhanced:

• Chapter 01: Introduction to Advanced PowerShell (13 files)
• Chapter 02: Advanced PowerShell Functions (41 files)
• Chapter 03: Working with Objects and the Pipeline (26 files)

Standards Applied:

• Full cmdlet names (no aliases): Get-ChildItem not gci
• Named parameters for clarity: -Path "C:\Temp" not positional
• Proper PowerShell verbs: Add, Get, Set, Remove, New, etc.
• ASCII diagrams for GUI/screenshot figures
• Cross-platform notes where applicable

Testing:
All scripts maintain their original functionality. Enhancements are limited to:

• Comments and documentation
• Formatting and structure
• Educational additions

No breaking changes to executable code.
