Microsoft is facing a lawsuit in California alleging that the company is ending support for Windows 10 prematurely to encourage sales of AI-enabled PCs and force users to upgrade to Windows 11. The lawsuit claims that this forced migration could jeopardize the security of sensitive user data. Approximately 400 million PCs still operate on Windows 10, and the plaintiff argues that support should not end until the operating system's market share declines significantly. Meanwhile, Microsoft continues to release security updates for Windows 10 versions 21H2 and 22H2, as well as for older versions, under patch KB5063709. Updates for Windows 11, including versions 23H2, are also being rolled out, with users urged to upgrade to maintain security protections.
