Overview

• Lawrence Klein filed the complaint in San Diego Superior Court in early August, seeking a court order to maintain free Windows 10 updates and security patches until the OS usage falls under 10 percent.
• The lawsuit alleges Microsoft set the October 14, 2025 end-of-support date to force users onto Windows 11-only PCs pre-configured for its Copilot generative-AI platform.
• Klein requests that Microsoft provide continued Windows 10 support at no additional cost and only seeks attorney’s fees beyond the injunctive relief.
• An estimated 240 million to 400 million PCs lack the hardware required for Windows 11 and face heightened security risks and potential e-waste if updates cease in October.
• The lawsuit is in its early stages and Microsoft has not issued a public response, making a resolution before the October 14 deadline unlikely.
