Sophia Script for Windows is a PowerShell-based system administration utility for fine-tuning Windows 10 and 11 installations. It provides over 150 configuration functions covering privacy, telemetry, UI personalization, security hardening, debloating, and system optimization. The tool is distributed as a PowerShell module with per-edition variants (Windows 10/11, LTSC, ARM, PowerShell 5.1/7) and includes a closed-source GUI wrapper (SophiaScriptWrapper.exe) for visual configuration. Architecture: The core is a PowerShell module (Sophia.psm1) with a preset file (Sophia.ps1) that users edit to select tweaks. The module loads private helper functions (Add-Policy, Get-Hash, WinAPI, etc.) and localization files. Execution flow: Import-TabCompletion.ps1 → InitialActions.ps1 (preflight checks) → user-selected tweaks → PostActions.ps1 (system refresh, toasts, restore points). The tool modifies Windows via registry keys, group policy (LGPO.exe), service management, scheduled tasks, and file association hashes. Key entry points: Sophia.ps1 (per edition) is the main preset; Import-TabCompletion.ps1 provides tab-completion; the Wrapper/ directory contains GUI config JSONs and the wrapper executable. External dependencies include LGPO.exe (Microsoft), WinRAR for packaging, and runtime downloads for HEVC codecs and cursor packs. The project is distributed via Chocolatey, WinGet, Scoop, and direct GitHub releases. Data flows: The script reads Windows build/version info, checks remote JSON manifests for updates, and applies changes based on user preset. It exports/imports file associations as JSON and creates restore points. Localization is handled via ConvertFrom-StringData .psd1 files in 12 languages. The tool is not a data pipeline or research project; it is a pure system configuration utility.
