Ghost Optimizer is an open-source, interactive optimization script designed to improve system performance, reduce latency, and make Windows faster, lighter, and more responsive. It applies deep system tweaks, removes bloatware, disables unnecessary services, blocks tracking and ads, and optimizes network settings — all in one streamlined process.
Whether you're on a low-end laptop or a high-end PC, Ghost Optimizer helps you get the most out of your hardware with minimal resource usage.
