Windows 11 can block Google Chrome’s 4GB AI model from reinstalling itself on your PC — A simple Registry tweak for “Pro” users

Microsoft has added a registry setting to Windows 11 that allows users to prevent Google Chrome from automatically downloading and installing a 4GB artificial intelligence model. The move comes after it was discovered that Chrome silently installs “weights.bin,” a large on-device AI model powering Gemini Nano features without user awareness.

The automatic installation prompted significant backlash from users concerned about the large file download and system resource consumption. Google responded defensively, arguing that the local AI model is designed to enhance user privacy rather than compromise it. The company emphasized that Gemini Nano powers important security features like scam detection and developer APIs, all executed locally without transmitting user data to the cloud.

Google dismissed claims that the model constitutes spyware or bloatware, positioning it as a privacy-first approach to AI-powered browser features. However, Microsoft’s decision to provide a mechanism to block the installation suggests the automatic deployment raised sufficient concerns to warrant user opt-out capabilities.

The registry tweak is available primarily for Windows 11 “Pro” users, allowing more granular control over what software and AI models are installed on personal computers. This development highlights ongoing tensions between major technology companies over default behaviors, user consent, and the automatic distribution of large AI models to consumer devices.
