Lawrence Klein, a California resident, has filed a lawsuit against Microsoft regarding the company's plans to retire Windows 10. Klein, whose laptops are incompatible with Windows 11 due to the lack of a Trusted Platform Module 2.0 (TPM), is seeking continued free updates for Windows 10 until its user base significantly decreases. He argues that Microsoft has violated California's business and consumer protection laws by forcing unnecessary upgrades and neglecting security updates for Windows 10 users. Support for Windows 10 is set to end on October 14, and Klein's legal team claims that many users are not prepared to transition to new devices or pay for extended support. Microsoft offers a paid extended support plan for Windows 10, but Klein is advocating for free support until Windows 10's market share falls below 10%. The lawsuit also criticizes the rapid phaseout of Windows 10, noting that historically, Microsoft has provided longer support periods for previous operating systems. At the time of the phaseout announcement, Windows 10 still held over 50% of the market share, with nearly 43% of users remaining on the older OS. Klein's argument suggests that the transition to Windows 11 has been expedited to benefit Microsoft and its hardware partners financially.
