A major shift is coming for millions of computer users as Microsoft officially ends support for Windows 10 on Tuesday, October 14. After that date, the widely used operating system will no longer receive security updates, leaving devices increasingly vulnerable to cyberattacks and software risks.
Who Will Be Affected?
Windows remains the world’s most popular operating system, powering over 1.4 billion devices globally. As of mid-2025, roughly 43% of those devices were still running Windows 10, according to Statcounter. In the UK alone, consumer group Which? estimates that 21 million people remain on Windows 10.
A recent survey found that one in four users plan to continue using Windows 10 despite the risks, while about one in seven intend to buy a new computer. Consumer advocates, however, warn that Microsoft’s decision could lead to unnecessary e-waste and additional costs for users.
“People are tired of living in a world filled with short-lived devices we can’t fix,” said Nathan Proctor, senior director at U.S. consumer group PIRG, calling the move “a disaster for both consumers and the environment.”
Your Options Going Forward
Microsoft has outlined two main options for users:
- Upgrade to Windows 11 for free – available for PCs that meet the system requirements.
- Sign up for Extended Security Updates (ESU) – a temporary measure that provides essential security patches for 12 months, with support extended until October 2026.
Users in the European Economic Area can access the ESU for free by registering, while others may need to pay around Ksh3,840 (£22) or redeem 1,000 Microsoft Rewards points. Commercial organizations will pay about Ksh7,808 per device, though fees vary by region.
To qualify, users must:
- Update to the latest version of Windows 10
- Have a Microsoft account
- Back up PC settings
The ESU program, however, does not include technical support or feature updates.
What Happens If You Don’t Upgrade
Without continued updates, Windows 10 devices will no longer receive protection from new security vulnerabilities, increasing exposure to viruses, ransomware, and other cyber threats. Over time, users may also find that third-party software stops working properly as developers shift support to newer systems.
Microsoft has encouraged users to upgrade to Windows 11, but not all older PCs meet the hardware requirements. This could force some consumers to buy new computers despite having devices that still function well.
Additionally, Microsoft is increasingly requiring users to log in with a Microsoft account to access key features, raising privacy concerns among those who prefer local-only accounts.
The Bigger Picture
Since its 2015 launch, Windows 10 has received regular updates and improvements, becoming one of Microsoft’s most stable and widely adopted platforms. Its end marks the close of an era — and the beginning of a new one focused on Windows 11’s cloud integration, security, and AI features.
But for many users and environmental advocates, the transition highlights the ongoing tension between technological progress, consumer choice, and sustainability.
