Millions of Windows 10 PCs Face Obsolescence as Microsoft Ends Support

The nine-year-old Lenovo ThinkPad sitting on my desk runs like new. Its fan spins quietly, the keyboard snaps with that satisfying click, and it handles email, video calls, and document editing without complaint. The only thing wrong with it, according to Microsoft, is that it exists.

Support for Windows 10 ended on October 14, 2025. Microsoft's official guidance for users in this position is direct: if your PC is unable to upgrade to Windows 11, you can buy a new PC. That advice lands differently when you consider the scope of who shares this ThinkPad's predicament. Canalys believes that a staggering 240 million PCs do not comply with Windows 11's requirements and are set to be rendered obsolete by Windows 10's October 14, 2025 support deadline, generating what the firm warned could become a catastrophic wave of electronic waste.

The barrier is not processing power or memory. Windows 11 requires TPM 2.0 with secure boot, a 1-GHz 64-bit dual-core CPU, 4GB of RAM, and 64GB of storage space, with Microsoft indicating that any processor older than an 8th-generation Intel Core series CPU or AMD Ryzen 2000 chip may be left out. A Lenovo ThinkPad from 2015 or 2016 carries a sixth- or seventh-generation Intel processor, built years before TPM 2.0 became standard in consumer hardware. It fails on the first test. Microsoft has set TPM 2.0 as a mandatory prerequisite for Windows 11, and has publicly restated it has no plans to lower the minimum requirements, asking users to upgrade their PCs instead.

For users unwilling to buy new hardware, Microsoft created a limited off-ramp. The Extended Security Updates program is available as a one-time purchase of $30, with a single license covering up to 10 devices and extending security patches through October 13, 2026. After that, the ESU program officially ends for home users, with no option to renew beyond 2026. The patch buys one year. It buys nothing permanent.

That arithmetic matters most for the institutions least equipped to absorb it. Schools running computer labs on older machines, public libraries, and low-income households dependent on secondhand hardware face a hard deadline with no durable solution on the other side. A replacement Windows 11 PC starts at several hundred dollars. The $30 ESU is a single-year bridge to the same cliff.

The beneficiaries of that pressure are not difficult to identify. PC manufacturers including Lenovo, Dell, and HP stand to gain from one of the largest forced upgrade cycles in computing history. Microsoft benefits from a more uniform, TPM-secured ecosystem and reduced legacy support costs. Those left behind are concentrated precisely among the demographics that digital equity advocates have spent years working to bring and keep online.

For machines that cannot go forward and whose owners cannot or will not replace them, Linux offers a genuine alternative. Distributions like Linux Mint and Zorin OS are designed specifically for this transition, with familiar desktop layouts and broad compatibility with older ThinkPad hardware. They cost nothing, require no license, and receive ongoing security updates entirely independent of Microsoft's product calendar.

Linux is not a universal solution. Users who rely on Windows-only software, enterprise environments managed through Windows Group Policy, or Microsoft 365 desktop applications rather than their browser-based equivalents will find switching difficult. For those users, the $30 ESU buys time to plan, not a permanent exit.

The ThinkPad on my desk, now running Linux rather than an unsupported Windows 10, receives regular security patches and costs nothing to maintain. For 240 million machines in the same position, the question was never whether Microsoft had the right to draw a deadline. It is who benefits from exactly where that line was drawn, and who was never consulted when it was.
