Windows 10 End of Support — 400 Million PCs and the "Planned Obsolescence" Debate

On 14 October 2025, Microsoft formally ended free support for Windows 10. Ten years and three months after the OS shipped on 29 July 2015 — a clean ten-year lifecycle, in line with the same treatment given to Windows 7 and 8.1.

But this EOL carried a colour no previous Windows EOL had. At the moment of cut-off, more than 40% of all Windows PCs in the world were still running Windows 10. When XP retired in April 2014, and when Windows 7 retired in January 2020, nowhere near that share of PCs reached the last day on the dying OS.

And the wall blocking the upgrade to Windows 11 was the same wall built four years earlier — the TPM 2.0 / 8th-generation-CPU requirement.

400 Million PCs Left Hanging

The figure repeatedly cited by Right to Repair Europe, the US consumer-advocacy group PIRG and others was roughly 400 million — the count of Windows 10 PCs that could not satisfy Windows 11's official hardware requirements (TPM 2.0, 8th-gen Intel Core or later, Secure Boot) and therefore had no sanctioned upgrade path.

Most of those PCs were not physically broken. Only their OS support had run out — security updates stopped, risk accumulating with every passing day they stayed online. "The largest case of forced obsolescence of physically functional PCs in history through a software-side decision" became the central framing for the critics.

That International E-Waste Day fell on the same date — 14 October — was widely quoted as irony beyond coincidence.

ESU: $30 and a "Free Loophole"

Microsoft's lifeline was the Extended Security Updates (ESU) programme. For the first time, ESU — historically enterprise-only — was opened to consumers.

• Paid: US$30 per year, per device, through 13 October 2026
• Free path 1: redeem 1,000 Microsoft Rewards points
• Free path 2: enable Windows Backup (OneDrive sync)

One important limit applied: there is no second year for consumers. The faucet shuts permanently on 13 October 2026. Enterprise customers can purchase up to three years (through October 2028), but consumers face the true final deadline twelve months in.

In the EU, under pressure from consumer groups, the conditions for the free path were relaxed. The criticism that mandatory OneDrive sync and a Microsoft account were "features-for-features bundling" was partially heeded.

E-waste and the Environmental Argument

Right to Repair Europe, Green Alliance, PIRG, 404 Media and others called the Windows 10 EOL an e-waste disaster.

• Estimated e-waste generation: around 700 million kg (PIRG put it at about 1.6 billion pounds)
• An independent 2022 study found roughly 43% of all PCs could not move to Windows 11
• The environmental cost of "replace your still-working PC with a brand-new Copilot+ PC" marketing

Microsoft's framing was consistent throughout: "this is the Copilot+ PC upgrade moment". Old PCs ought to be replaced with the next generation of AI PCs — a commercial story.

The counter-argument: at the XP and Windows 7 EOLs, hardware requirements were essentially unchanged, so users could upgrade the same PC to the new OS. At the Windows 10 → 11 boundary, the OS's own security requirements physically excluded older PCs. "It looks like the same kind of EOL, but what's actually happening is completely different."

Geopolitical Risk — Unpatched at Scale

A separate axis of concern came from cybersecurity.

To threat actors based in China, Russia or North Korea, every Windows 10 PC online after 15 October 2025 is a permanently vulnerable attack surface. Ordinary households without ESU, small businesses, work PCs in developing economies, legacy terminals in schools and hospitals — all kept running, unable to receive a patch for any zero-day discovered after the cut-off.

Specialists who remember how WannaCry (2017) used an SMB v1 exploit to tear through unpatched XP and 7 globally treated the Windows 10 EOL as fuel for the next WannaCry. National infrastructure, hospitals, ATMs — many of these still run on Windows 10 / 11 IoT Enterprise LTSC builds. The exposure is real.

What Was Recorded

The Windows 10 EOL will be remembered not as another generational OS handover, but as the event that confirmed an era in which a major OS update is an economic, environmental and geopolitical event in its own right.

From the technology side: TPM 2.0, Secure Boot, VBS, Pluton, Copilot+ PC — the line Microsoft drew four years earlier simply closed on schedule in 2025. The strategy was coherent.

From the user side: PCs bought between 2015 and 2019, physically intact, were placed in an "officially cannot move on" state — and offered a choice between US$30 a year and mandatory OneDrive sync.

From the environmental side: 700 million kg of candidate e-waste, and tailwind for the right-to-repair movement seeking legislation in the EU.

Windows 10 the OS embodied Microsoft's own 2015 promise — "Windows major updates will be free" and "upgrades will not be gated by hardware". When its ten years ended, that promise ended with it. That is what gives this EOL its weight.
