Overview

• Lawrence Klein filed a complaint in San Diego Superior Court on August 9 seeking an injunction to force Microsoft to keep Windows 10 updates free until its share drops below 10%.
• The suit alleges Microsoft timed the October 14, 2025 end-of-support to push customers into buying Windows 11-capable PCs built for its Copilot AI features.
• About 45% of Windows users—around 700 million devices—remain on Windows 10, and an estimated 240 million lack the TPM 2.0 module required for an official Windows 11 upgrade.
• Klein contends that discontinuing free updates will leave many users exposed to heightened cyberattack risks on unsupported systems.
• The complaint claims the support cutoff is designed to solidify Microsoft’s control over the generative AI market and block rival products.
