This repository is a historical archive of system-level automation scripts and binaries created in 2022 during my early work with Windows 10 OS internals, network latency reduction, and PC performance tuning.
Context & Background: Originally developed to extract maximum gaming performance for my personal setup and provided as a custom optimization service for other gamers during that time. These scripts make aggressive, low-level modifications to registry parameters, network adapter bindings, MMCSS task priorities, and system power states specifically for Windows 10 builds (circa 2022). They are preserved here purely for educational, portfolio, and historical purposes. Do not run these scripts on modern production machines without a prior code audit.
- Protocol Disabling: Suppresses legacy IPv6 transition technologies (
Teredo,6to4,ISATAP) to eliminate network stack overhead and latency spikes. - TCP/IP Stack Tuning: Configures global TCP parameters (heuristics, chimney offload, congestion provider) for streamlined packet handling.
- Adapter State Overrides: Disables Large Send Offload (LSO) and network interface power-saving states via PowerShell to prevent packet queuing delays.
- Registry Overrides: Direct edits to
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parametersto maximize TCP window sizing and packet throughput.
- Multimedia Class Scheduler: Adjusts MMCSS execution priorities and scheduling metrics under
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfileto prioritize game tasks. - Throttling Removal: Disables network throttling index constraints and sets
SystemResponsivenessto 0, ensuring maximum CPU resource allocation for active foreground applications.
- Power Scheme Override: Activates Ultimate or High Performance power schemes using
powercfgto prevent CPU core parking and micro-stuttering. - Sleep/Timeout Settings: Disables disk spin-down and power sleep state transitions during active system usage.
- Packed PE binaries compressed using the Ultimate Packer for Executables (UPX) to analyze binary header section behavior (
UPX0,UPX1).
