1. Appearance Tweaks

Path: Tweaks/Appearance/
Purpose: Disables taxing visual transitions and unnecessary system components to free up CPU and GPU cycles on older systems.

Available Registry Tweaks

Dark Theme.reg / Light Theme.reg: Swaps the Windows system and app themes between dark and light modes.
Disable Transparency.reg / Enable Transparency.reg: Turns off transparency effects on the taskbar, start menu, and action center. Disabling transparency significantly reduces GPU load in windowed modes.
Disable Action Center.reg / Enable Action Center.reg: Deactivates the system notifications tray.
Disable Cortana.reg / Enable Cortana.reg: Fully blocks the Cortana digital assistant search indexing and background services.

[!TIP] Disabling transparency and transitions is highly recommended for legacy systems with integrated graphics cards (such as Intel HD Graphics) to prevent interface stuttering.

2. Background Tweaks

Purpose: Frees up local network bandwidth and stops background update uploads.

Available Registry Tweaks

Cap Delivery Optimization Bandwidth.reg / Remove Bandwidth Caps (Restore).reg: Caps background download/upload bandwidth used for Windows Update delivery optimizations to prevent network spikes while gaming.
Disable Peer to Peer Updates.reg / Enable Peer to Peer Updates (Restore).reg: Prevents Windows from uploading updates to other PCs on the internet (which severely chokes home upload bandwidth).

7. Privacy Tweaks

Path: Tweaks/Privacy/
Purpose: System-wide blockades to prevent background telemetry transmission and device snooping.

Available Registry Tweaks

Disable App Metadata Access.reg / Enable App Metadata Access.reg: Stops Windows from scanning app configurations.

8. Recursos & Resources (Standard Tweaks)

Path: Tweaks/Recursos/ & Tweaks/Resources/
Purpose: The traditional performance tweaks folder.

Key Components

CPU Priorities

Games Priority.reg: Modifies the Multimedia Class Scheduler (MMCSS) to allocate up to 80% CPU resources directly to active games and applications.
Windows Priority.reg / Revert Changes.reg: Restores balanced desktop thread priority parameters.
Registry Paths Modifed: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games

CPU Mitigations

InSpectre.exe: A lightweight diagnostic utility that allows the safe enabling/disabling of Meltdown and Spectre hardware mitigations.
- Mitigations OFF: Restores lost CPU performance (highly noticeable on 8th Gen Intel processors and older), but exposes the system to theoretical security exploits.
- Mitigations ON: Maximum security configuration, but reduces disk read/write throughput and raw execution speeds.

CPU Power Plans

QuickCPU.pow: A custom-engineered system power configuration optimized to minimize CPU core parking, maintain high frequency scales longer, and disable standard power savings when processing active loads.
Aplicar.bat / Apply.bat: Shell scripts to import and active the custom power plan via command line.
Terminal window
```
powercfg -import "%~dp0QuickCPU.pow"
```

SSD Optimizations

Optimizar SSD.reg / Revert Changes.reg: Applies SSD-specific settings:
- Enables TRIM to ensure even wear on NAND flash cells.
- Disables Superfetch / Prefetch (redundant on solid-state drives, saves excess disk write cycles).
- Optimizes standard disk write caching values.

Memory Reduction

Mem Reduct RAM (Portable): A light memory management utility.
- Cleans system caches, working sets, and pagefiles on command.
- Configures cleanups when memory saturation crosses specific benchmarks (e.g., 85%).
- Essential for legacy hardware configurations equipped with less than 8GB of RAM.

RAM Compression

Disable Compression.cmd / Revert Changes.bat: Toggles Windows virtual memory compression.
- Compression Disabled: Eliminates CPU processing latency associated with compressing inactive RAM pages. Best for systems with 16GB+ RAM.
- Compression Enabled: Compress pages to conserve capacity. Recommended for systems with 4GB/8GB RAM to prevent immediate swapfile thrashing on slow HDDs.

System Services

Optimize Services.reg: Disables or sets to Manual a wide array of legacy, enterprise, and telemetry-related background services (e.g., Bluetooth, print spooling if unused, faxing, remote registries).

Telemetry & Data Collection

Disable Telemetry.reg: Blocks telemetry routines, CEIP diagnostic collection, and Windows feedback prompts.

9. Startup Tweaks

Path: Tweaks/Startup/
Purpose: Manages software launch profiles during system startup.

Active Utility

Manage Startup Apps.ps1: PowerShell script to scan, identify, and disable heavy third-party auto-starting applications in registry locations like: HKLM\Software\Microsoft\Windows\CurrentVersion\Run HKCU\Software\Microsoft\Windows\CurrentVersion\Run

10. Storage Tweaks

Path: Tweaks/Storage/
Purpose: Automates standard garbage collection and frees up wasted gigabytes.

Tools

Enable Storage Sense.reg / Disable Storage Sense (Restore).reg: Toggles Windows Storage Sense utility, which automatically deletes temporary files, clears the Recycle Bin, and cleans downloaded items at set intervals.
Safe Temporary Cleanup.bat: A non-destructive shell script that purges the following cache directories safely:
- %temp% (User Temporary directory)
- C:\Windows\Temp (System Temporary directory)
- C:\Windows\Prefetch (Prefetch system files)

11. Storage-Aggressive Tweaks

Path: Tweaks/Storage-Aggressive/
Purpose: Sweeps system files and component stores for deeper debloating.

Active Utility

Deep Component Cleanup (Aggressive).bat: A script that must be run as Administrator. It uses the Deployment Image Servicing and Management (DISM) tool to purge superseded system files, unused component packages, and legacy update backups from the WinSXS folder.
Commands executed:
Terminal window
```
Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase
```
[!WARNING] Running this aggressive component store cleanup removes old update uninstall files permanently. You will not be able to uninstall current updates once completed.

12. Troubleshooting Tweaks

Path: Tweaks/Troubleshooting/
Purpose: Restores system variables back to isolated baseline states.

Tools

Clean Boot Manager.ps1: A PowerShell diagnostic utility that disables all non-Microsoft startup applications and services, creating an isolated boot profile. Extremely useful for identifying game-crashing software components or overlay conflicts.

13. WPF Dashboard Walkthrough

Path: Start.bat -> Launch_Dashboard.ps1
Purpose: The central menu interface.

The framework now features a stunning native PowerShell + WPF XAML graphical dashboard. Double-click Start.bat to launch it. The dashboard consists of multiple tabs:

Optimization Profiles:
- Max Performance Mode: Targets the absolute lowest DPC latency and highest thread priorities for elite gamers.
- Balanced Creator Mode: Optimizes Windows Explorer and removes bloatware without disabling Windows Updates or breaking creative apps.
- Enterprise Compliance Mode: Reverts the OS into a highly secure, privacy-hardened state for corporate usage.
Observability Telemetry: A real-time dashboard leveraging high-speed .NET Diagnostics to monitor DPC latency proxy speeds, Available RAM, Uptime, and Active Process Counts.

- Reducing visual effects quality parameters.
- Applying MMCSS gaming priority.
- Setting active game processes (like CS:GO, CS2, Fortnite, Minecraft, GTA V) to high performance CPU scheduling execution properties.
Create Restore Point: Highly recommended first step. It runs PowerShell to enable system restores and establish a safe baseline bookmark named “Optimizer Script”.
Delete Temporary Files: Automatically cleans the user temp, system temp, and prefetch storage directories.
Disable Windows Defender: Menu options to switch active Windows Defender, Security Health, and real-time monitoring services off.
Disable Windows Update: Menu to pause and stop update schedulers and update self-healing dll dependencies.
