Microsoft's 2025 Hardware Mandate: Why Millions of UK PCs Are About to Become Obsolete
On 14 October 2025, Microsoft will stop releasing security updates for Windows 10. That deadline is now less than seven months away, and according to StatCounter, approximately 62% of Windows PCs in the UK are still running Windows 10. The kicker? Many of those machines cannot officially upgrade to Windows 11 — not because they are too slow, but because they lack a tiny security chip called TPM 2.0.
This is shaping up to be the biggest forced hardware obsolescence event in PC history. Here is what it means for UK users, what your options actually are, and why Microsoft's approach is generating serious criticism.
The Windows 10 End-of-Life Timeline
Let us be precise about what happens on 14 October 2025:
- No more security updates — newly discovered vulnerabilities will not be patched.
- No more bug fixes — existing issues will not be resolved.
- No more feature updates — Windows 10 is frozen in its current state.
- Your PC still works — it does not stop functioning. It just becomes increasingly unsafe to connect to the internet.
Microsoft is offering Extended Security Updates (ESU) for consumers for the first time — £24 per device per year. But this is a sticking plaster, not a solution. ESU only covers critical and important security updates, and Microsoft has confirmed it will only be available for one year (until October 2026).
Why Millions of UK PCs Cannot Upgrade
Windows 11 has the strictest hardware requirements of any Windows version:
| Requirement | Minimum | Why It Matters |
|---|---|---|
| CPU | Intel 8th Gen / AMD Ryzen 2000+ | Excludes PCs older than ~2018 |
| TPM | Version 2.0 | Many pre-2016 PCs lack this entirely |
| RAM | 4 GB | Reasonable — most PCs meet this |
| Storage | 64 GB | Reasonable — most PCs meet this |
| Secure Boot | UEFI with Secure Boot | Some older PCs use legacy BIOS |
The CPU requirement is the real gatekeeper. Intel's 7th-generation Core processors — which were flagship products in 2017 and remain perfectly capable of running modern software — are explicitly blocked. A Core i7-7700K from 2017 outperforms a Celeron N4020 from 2020, yet the Celeron meets the requirements and the i7 does not.
This is not about capability. It is about Microsoft drawing an arbitrary line.
The Environmental Cost Nobody Is Talking About
Here are the numbers that should concern every UK policymaker:
- 240 million PCs worldwide are estimated to be ineligible for Windows 11 (Canalys research).
- A typical desktop PC produces approximately 300 kg of CO2 during manufacture.
- If even half of those PCs are replaced, that is 36 million tonnes of CO2 — equivalent to the annual emissions of a small country.
- E-waste is already the fastest-growing waste stream in the UK, at 23.9 kg per person per year (higher than the EU average).
The UK government has committed to reaching net zero by 2050. Forcing millions of functional PCs into landfill because of a software requirement contradicts that goal directly.
Environmental organisations including Greenpeace have criticised Microsoft's approach, calling it 'planned obsolescence dressed up as security.' The German Federal Environment Agency (UBA) has taken a similar stance, urging Microsoft to extend Windows 10 support or relax Windows 11 requirements.
Your Options as a UK User — Ranked
If your PC does not meet Windows 11's official requirements, here is what you can actually do, from best to worst:
Option 1: Upgrade to Windows 11 Anyway (Best for Most People)
Tools like Rufus allow you to create Windows 11 installation media that bypasses the TPM 2.0 and CPU checks. Your PC will install and run Windows 11 normally. Microsoft has acknowledged this workaround exists but warns that unsupported PCs might not receive all future updates.
In practice, as of early 2025, unsupported PCs are still receiving all Windows 11 updates. Microsoft has not yet enforced any restrictions.
Cost: £19.99 for a Windows 11 Pro key from Softkeys.uk — a fraction of the cost of a new PC.
Option 2: Pay for Extended Security Updates (£24/year)
Stay on Windows 10 and pay Microsoft £24/device/year for continued security patches. This buys you one additional year (until October 2026). After that, you are on your own.
This makes sense if you are planning to replace the PC within the next year anyway. It does not make sense as a long-term strategy.
Option 3: Switch to Linux
Linux Mint, Ubuntu, and Zorin OS are all viable alternatives that run beautifully on older hardware. They are free, receive regular security updates for years, and handle web browsing, email, and document editing without issue.
The trade-off: no native Microsoft Office (use the web version or LibreOffice), limited gaming support (though this has improved dramatically via Steam's Proton), and some specialised software may not have Linux versions.
Option 4: Buy a New PC
If your PC is genuinely from 2015 or earlier, it may be time. But do not let Microsoft's arbitrary requirements push you into a premature purchase. A 2017 PC with an SSD and 8 GB of RAM is still a capable machine for most tasks.
Option 5: Do Nothing (Not Recommended)
Keep running Windows 10 without updates. Your PC will continue to work, but every month without security patches increases your exposure to malware, ransomware, and data theft. If you do online banking or handle any sensitive data, this is genuinely risky.

What Microsoft Should Be Doing
The tech community has largely agreed on what a responsible approach would look like:
- Extend Windows 10 security updates to 2028 — giving everyone a proper transition window.
- Make TPM 2.0 recommended, not required — let users accept the security trade-off on older hardware.
- Remove the CPU whitelist — if a processor can run Windows 11 competently, let it.
- Partner with recycling programmes — if obsolescence is unavoidable, mitigate the environmental impact.
Microsoft has done none of these things. The £24/year ESU programme is their only concession, and it is time-limited.
The UK Regulatory Angle
The UK is currently developing its right-to-repair framework. The Department for Environment, Food and Rural Affairs (DEFRA) has been consulting on extending product lifespans and reducing e-waste. Software-driven obsolescence of hardware falls squarely within this conversation.
The Consumer Rights Act 2015 requires digital products to be of satisfactory quality and fit for purpose. Whether a software company can deliberately end support for a product that still functions — effectively forcing hardware replacement — is a question UK consumer law has not yet fully addressed.
Several UK consumer organisations, including Which?, have called on Microsoft to provide free extended support or relax its hardware requirements. So far, Microsoft has not budged.
The Smart UK User's Playbook for 2025
Here is what we recommend based on your situation:
Your PC is from 2018 or newer (Intel 8th Gen+ / Ryzen 2000+)
You almost certainly meet Windows 11 requirements. Run Microsoft's PC Health Check tool to confirm. If eligible, upgrade to Windows 11 Pro — £19.99 from Softkeys.uk. This is the simplest path.
Your PC is from 2015–2017 (Intel 6th/7th Gen)
Your PC is powerful enough for Windows 11 but officially unsupported. Use Rufus to create a bootable USB that bypasses the requirements, install Windows 11, and carry on. Your PC has years of life left.
Your PC is from 2014 or earlier
At this point, the hardware is genuinely ageing. Consider whether a new PC or a switch to Linux makes more sense. If the PC handles your current tasks fine, Linux Mint is an excellent option that will keep it secure and functional for years.
The bottom line: Microsoft's 2025 deadline is real, but it does not mean your PC is worthless. A £19.99 Windows 11 Pro key and 30 minutes of your time can extend a perfectly good computer's life by years. Do not let artificial obsolescence push you into spending hundreds on a new machine you do not need.
