Cat-System is a modular Windows optimization tool. Each module runs independently, all changes are logged, and everything can be reverted with a single command. | Single File & Moduler Mode
| 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 |
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.ps1For 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.
- Right-click
Start-CatSystem.ps1→ Run with PowerShell (or launch from an elevated terminal) - Pick a module number from the menu
- Each module measures a benchmark before and after, and writes everything to
CatSystem_Log.txt - Run
[7] Rollbackat any time to undo all changes
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.
- 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
