:: ==========================================================================================
:: DESCRIPTION:
::   Comprehensive 15-step Windows deep optimizer for Windows 10 and 11.
::   Performs system cleanup, performance tuning, and service optimization
::   to reduce disk usage, improve responsiveness, and free up system resources.
::
::   OPTIMIZATION STEPS:
::     01. Disable Reserved Storage (frees disk space reserved by Windows)
::     02. Disable Hibernation (removes hiberfil.sys, frees ~4-32GB)
::     03. Disable unnecessary startup services
::     04. Enable SSD TRIM (ensures optimal SSD performance and longevity)
::     05. Disable visual effects (maximizes performance, reduces GPU load)
::     06. Clean Temp folders (removes user and system temporary files)
::     07. Run Disk Cleanup with extended CleanMgr flags
::     08. Fix network stack (reset Winsock, TCP/IP, DNS cache)
::     09. Set High Performance power plan
::     10. Disable Windows Telemetry and data collection
::     11. DISM: Analyze and cleanup WinSxS component store
::     12. DISM: RestoreHealth - repairs Windows image from Windows Update
::     13. DISM: StartComponentCleanup - removes superseded components
::     14. SFC: System File Checker - repairs corrupted system files
::     15. CompactOS: Compresses the OS install (saves ~1.5-2.5GB)
::
:: REQUIREMENTS:
::   - Windows 10 / Windows 11
::   - Must be run as Administrator
::   - Active internet connection (for DISM RestoreHealth step)
::   - Reboot is recommended after completion
::
:: USAGE:
::   1. Right-click WIN_Optimize.bat -> Run as administrator
::   2. Each step runs sequentially with status output
::   3. Restart Windows after the script completes for full effect
::
:: WARNING:
::   - Step 02 (Hibernation OFF) removes hiberfil.sys permanently
::   - Step 10 (Telemetry OFF) disables DiagTrack and related services
::   - Step 15 (CompactOS) may take 15-60 min depending on disk speed
