Lawrence Klein has filed a lawsuit against Microsoft in California, alleging that the company is violating consumer and business laws by discontinuing support for Windows 10 before its users are ready to transition. He claims that the hardware requirements for upgrading to Windows 11 are excessive, affecting around 240 million devices that do not meet these standards. Approximately 43% of users are still on Windows 10, indicating a disconnect between Microsoft's expectations and actual user adoption. Klein criticizes Microsoft's marketing tactics, suggesting they prioritize sales over user satisfaction. Although Microsoft has provided a decade of support for Windows 10, Klein argues that recent concessions are insufficient. The lawsuit highlights growing user discontent and may pressure Microsoft to reconsider its approach to Windows 10's End of Life.
