Millions of computer owners face a crucial deadline this autumn. Microsoft will officially end support for Windows 10 on Tuesday, 14 October. After that day, the system will stop receiving vital security updates, leaving devices more vulnerable to hackers and malware. Without patches, older machines could quickly become unsafe. Microsoft urges users to upgrade to Windows 11 for free, but many computers cannot meet the required specifications. Nathan Proctor, senior director at US consumer group PIRG, warns the move could harm both consumers and the environment.
Windows 10 still powers millions of devices
Windows remains the most popular computer operating system on the planet. Microsoft says it runs on more than 1.4 billion devices worldwide. According to Statcounter, around 43% of them were still using Windows 10 as of July 2025. In the UK, consumer organisation Which? estimates that 21 million people continue to rely on the ageing system. A recent survey found that one in four users plans to keep using Windows 10 even after support ends, while one in seven expects to buy a new computer.
Consumer advocates have criticised Microsoft’s decision, calling it wasteful and expensive. “People are tired of short-lived products that lose support too soon,” said Proctor. “We deserve technology that lasts,” he added.
What users can do before October
Microsoft offers two main options for personal users. They can upgrade to Windows 11 or subscribe to extended security updates (ESU) for another year. Both options can be managed in the “Privacy and Security” section of system settings. Users with compatible PCs can upgrade for free. However, many will have to buy new devices even if their current ones still work well.
For users who can’t or don’t want to upgrade, Microsoft provides ESU, which offers essential security updates until October 2026. ESU doesn’t include new features or technical support. People living in the European Economic Area can register for free. Others can qualify by updating to the latest version of Windows 10, creating a Microsoft account, and backing up their settings.
If users don’t meet those conditions, they’ll need to pay $30 (£22) or use 1,000 Microsoft Rewards points to access ESU. For companies, the fee is $61 per device, depending on location.
What will change after support ends
Since its 2015 launch, Windows 10 has received steady updates that improved performance, added features, and fixed security flaws. Now, Microsoft encourages users to switch to Windows 11, which requires newer hardware and a Microsoft account for full access. Even ESU subscribers must have a Microsoft account. Some users have raised privacy concerns about this requirement.
Why staying on Windows 10 is risky
Once Microsoft ends support, Windows 10 PCs will no longer receive critical security patches. That will make them increasingly vulnerable to cyberattacks, viruses, and ransomware. Without protection, defences will weaken over time.
Recent cyber incidents have hit major retailers, car manufacturers, and even childcare providers. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that businesses running unsupported software could face compliance issues and security breaches. Developers may also stop supporting Windows 10, leading to reduced functionality in apps and programs.
For millions of users, the clock is ticking. Upgrading ensures protection and stability, while staying with Windows 10 could leave your computer exposed to growing digital threats.
