You must be well aware of Microsoft recently announcing the end of support for Windows 10, and as we're just a bit over two months ahead of this happening, users are bound to take extra care when making next PC upgrade choice.
The looming Windows 10 end-of-support game has left millions of Windows 10 users compelled to enrol in Microsoft’s Extended Security Updates (ESU) programme, where they pay for an additional year of security patches.
On the other hand, a big chunk of Windows 10 users is shifting to Windows 11, irrespective of meeting the bare-minimum hardware requirement for its installation, not to mention a big number of users reportedly switching to alternatives like Linux.
Who sued Microsoft for ending Windows 10 support?
But neither of these options seemed a go-to one for a Windows 10 user, as he's sued Microsft for making people make such choices, which seems a bid to delay the operating system’s retirement.
Citing a report from Courthouse News Service, Lawrence Klein, a Windows 10 user with two laptops that cannot upgrade to Windows 11, has filed a lawsuit against Microsoft.
What's Lawrence Klein's lawsuit against Microsoft?
The Windows 10 user argues in his lawsuit that the company’s decision to end support will make millions of devices obsolete and force users to buy new Windows 11 machines in which Microsoft’s AI assistant, Copilot, comes in-built.
Klein is of the view that this strategy gives Microsoft an unfair advantage in what he terms the “generative AI market,” as customers are getting influenced in favour of hardware and software ecosystems controlled by the company.
His lawsuit demands that free Windows 10 support be extended until the operating system’s market share falls below 10%. Currently, Windows 10 accounts for about 43% of installations worldwide, which he views to be too high to justify ending updates.
If Klein’s lawsuit encounters failure, users will have be left with limited options, including switching to a newer system or paying for extended support, which will likely accompany further restrictions.
