The Ultimate Modular Windows 10 & 11 Optimization and Debloat Suite
A comprehensive, highly modular collection of 167+ safe Windows optimizations organized into 12 standalone categories. Stop relying on "nuclear" one-click scripts that break your OS. Choose exactly what you want to optimize.

Most Windows debloat scripts run blindly, disabling critical services like Windows Update or Defender, leading to system instability. Win-Optimize-Debloat-Toolkit takes a different approach:
- Modular Architecture: Don't want to mess with your network stack? Just skip folder
05. You have total control. - Deep Performance Tuning: We go beyond just removing bloatware. We tune your CPU's C-states, disable kernel paging, fix NDU memory leaks, and disable telemetry at the policy level.
- Transparent & Reversible: Every single
.batfile is paired with its ownREADME.mdexplaining exactly what registry keys and services are being modified, with clear instructions on how to undo them. - Hardware Aware: Scripts auto-detect if you are running on an SSD or HDD, and adapt memory and SysMain optimizations accordingly.
Dive into any folder to read the specific documentation for those tweaks.
| # | Module | Tweaks | What It Does |
|---|---|---|---|
01 |
Power & CPU | 14 | Unlocks Ultimate Performance, disables core parking, aggressive CPU boost, disables power throttling. |
02 |
GPU & Display | 9 | Enables HAGS, kills Game DVR overhead, disables MPO (fixes Intel stutter), maximizes GPU priority. |
03 |
RAM & Memory | 8 | Locks kernel in RAM, fixes NDU memory leaks, optimizes pagefile based on SSD/HDD detection. |
04 |
Disk & Storage | 10 | Tunes NTFS parameters, verifies SSD TRIM, disables Windows Search indexer, turns on Storage Sense. |
05 |
Network & Internet | 22 | Lowers latency by killing the Nagle algorithm, frees QoS bandwidth, tunes DNS, disables IPv6 overhead. |
06 |
Telemetry Killer | 10 | Stops Windows from phoning home (DiagTrack, CEIP, WAP Push, Error Reporting). |
07 |
Useless Services | 34 | Safely disables resource-heavy background services (Xbox, Maps, Mixed Reality, Peer Networking). |
08 |
Scheduled Tasks | 16 | Silences hidden background tasks that cause surprise CPU/Disk spikes (CompatTelRunner, Device Census). |
09 |
Privacy & Ads | 18 | Removes Start menu ads, Copilot, Recall, Activity History, and restores the classic Win11 right-click menu. |
10 |
Visual Performance | 11 | Strips animations and fade effects for a snappy, instant UI response. |
11 |
System Cleanup | 10 | A safe-to-run-weekly cache purger (Temp, Prefetch, Windows Update downloads, WER dumps). |
12 |
System Repair | 5 | Interactive menu to run DISM Cleanup, RestoreHealth, SFC scans, and Windows Update resets. |
Total: 167 targeted optimizations across 12 categories.
- Clone or download this repository to your local machine.
- Navigate to the specific category you want to apply (e.g.,
01_power_and_cpu). - Right-click the
.batfile inside the folder and select Run as Administrator. (Note: All scripts contain auto-elevation logic, but manual elevation is best practice). - Follow any on-screen prompts.
- Reboot your computer to ensure all registry and service changes take effect.
Want the "Full Send"?
We've included a master script at the root level: ULTIMATE_SYSTEM_OPTIMIZER.bat (if available in your setup) which chains these together.
⚠️ Always create a System Restore Point before running any script.- Non-Destructive: These scripts modify configurations and disable services; they do not delete critical system files.
- Easy Undo: Changed your mind? Open the
README.mdinside any category folder. You will find explicitcmdcommands to revert every change made by that specific module.
This project stands on the shoulders of giants. We've synthesized the best, safest patterns from the top optimization projects of 2024–2025:
| Project | Contributions to this Toolkit |
|---|---|
| Win11Debloat | ContentDeliveryManager ad removal, Copilot/Recall disabling, classic context menu restore. |
| ChrisTitusTech/winutil | Service categorization safety, TCP/Network tuning, Windows Update reset pipeline. |
| Sophia-Script-for-Windows | Advanced Memory management (IoPageLockLimit), NTFS tuning, Explorer defaults, Privacy registry keys. |
- Operating System: Windows 10 (Build 19045+) or Windows 11 (Build 22000+)
- Architecture: 64-bit (x64)
- Permissions: Administrator privileges are required.
