On August 10th, according to Courthouse News Service, Lawrence Klein, who lives in Southern California, filed a lawsuit in San Diego Superior Court against Microsoft's plan to stop support for Windows 10 on October 14, 2025.

According to reports, Klein owns two Windows 10 laptops, which will no longer be supported after October. He claimed that Microsoft's move was to "force customers to purchase new devices that can run Microsoft's generative artificial intelligence (AI) software suite, such as Copilot bundled with Windows 11.

Currently, upgrading from Windows 10 to Windows 11 is free, but millions of devices are unable to upgrade due to the lack of a critical requirement - Trusted Platform Module 2.0 (TPM 2.0). Microsoft stated that TPM 2.0 is a mandatory requirement for all future versions of Windows, and devices that do not have this module installed are not eligible for the upgrade. Although users can bypass this requirement through certain methods, it will result in the device losing official support and making it difficult to obtain technical support from Microsoft in case of any issues.

Individual users can extend the support period of Windows 10 for one year through the Extended Security Update (ESU) program by making a one-time payment of $30 (IT Home note: the current exchange rate is approximately 215.6 RMB), but this requires a Microsoft account. The requirement to create a Microsoft account to log in to Windows 11 is one of the reasons why some Windows 10 users refuse to upgrade. Therefore, the ESU plan may not be feasible for these users either. For many people, they may have to grit their teeth and spend money on new devices to upgrade their systems; However, others suggest switching to Linux.

Klein requested the court to force Microsoft to continue providing free support for Windows 10 until its market share drops below 10% of all Windows users. If the court supports his claim, it will bring additional costs to Microsoft and may delay the popularity of Windows 11. After all, although Microsoft released the latest Windows 11 nearly four years ago, it wasn't until this year that Windows 11 surpassed Windows 10 in market share, possibly due to the upcoming discontinuation of support for Windows 10.

There are only a few months left until Microsoft stops supporting Windows 10, and we are unlikely to see the outcome of this case before then. In addition, Microsoft is likely to use its almost unlimited funds and large legal team to bring this lawsuit all the way to the Supreme Court.
