Modules

Module	What it does
🛡️ Ghost Protocol	Disables telemetry, ad tracking, Bing search in Start, location, Activity History and consumer features — also blocks telemetry hosts, disables scheduled tasks and stops diagnostic services
⚡ Sculptor Engine	Throttles background processes, activates High Performance power plan, tunes memory settings
🚀 Net Booster	Flushes DNS cache, resets Winsock/TCP stack, configures TCP parameters and DNS cache TTL
🧹 Browser Cleaner	Wipes cache, cookies and history for Chrome, Edge, Firefox, Opera and Brave
⚙️ Startup Manager	Lists, adds and removes startup entries from both Registry and Startup folder
🧹 System Cleaner	Clears temp folders, Windows logs and Prefetch cache — also runs DISM and Storage Sense
⏪ Rollback	Reverts every registry, file, scheduled task and hosts change made during the session

🔨 Build

Requirements:

• Windows 10 or 11
• PowerShell 5.1 (built-in) or PowerShell 7.x
• Administrator privileges

git clone https://github.com/tc4dy/Cat-System.git
cd Cat-System

# Run directly
.\Start-CatSystem.ps1

# Or set execution policy for the current session
Set-ExecutionPolicy -Scope Process Bypass -Force
.\Start-CatSystem.ps1

For the single-file portable version, run CatSystem.ps1 from any directory — no installation required.

Always run as Administrator — registry and system service access requires elevated privileges.

---

🚀 Usage

1. Right-click Start-CatSystem.ps1 → Run with PowerShell (or launch from an elevated terminal)
2. Pick a module number from the menu
3. Each module measures a benchmark before and after, and writes everything to CatSystem_Log.txt
4. Run [7] Rollback at any time to undo all changes

---

🔒 Rollback & Safety

Every registry value, file, scheduled task and hosts entry is backed up to CatSystem_Rollback/ before anything is touched. The Rollback module restores all of them in one shot. Hosts modifications are tracked with begin/end markers, so only Cat-System's own block is removed on rollback — not the entire file.

---

📋 Notes

• Net Booster and Sculptor Engine require a restart for some changes to apply
• Close browsers before running Browser Cleaner
• DISM cleanup can take a few minutes depending on the WinSxS store size
• All registry tweaks go through the Group Policy layer (Software\Policies) — system-wide and persistent
• Rollback only covers changes made during the current session; clearing the backup folder makes them permanent
