A major deadline is drawing near for computer users worldwide. Microsoft will officially stop supporting Windows 10 on Tuesday, 14 October. After that date, millions of computers will lose vital security updates, leaving them more vulnerable to attacks. Without these updates, hackers and malware will have an easier time targeting older systems. Microsoft is urging users to upgrade to Windows 11 for free, though many older devices will not meet its hardware requirements. Nathan Proctor, senior director at the US consumer group PIRG, warns that the change could harm both consumers and the environment.
Millions still running on Windows 10
Windows remains the world’s most popular operating system. Microsoft reports that it runs on more than 1.4 billion devices globally. According to Statcounter, about 43% of them were still using Windows 10 in July 2025. In the UK, consumer organisation Which? estimates that 21 million people continue to rely on Windows 10. A September survey found that roughly a quarter of those users plan to keep using it even after official support ends. Around one in seven said they plan to buy a new computer instead.
Consumer groups have criticised Microsoft’s decision, arguing that it will create unnecessary costs and increase electronic waste. “People are tired of devices that can’t be fixed or quickly lose software support,” said Proctor. “We deserve technology that lasts,” he added.
What steps users can take now
Microsoft offers two main options for personal users. They can upgrade to Windows 11 or subscribe to extended security updates for an additional year. Both options can be accessed in the “Privacy and Security” section of system settings. Users with compatible devices can upgrade to Windows 11 for free. However, many will need to buy new computers, even if their current ones still perform well.
For those unable or unwilling to upgrade, Microsoft provides the Extended Security Updates (ESU) programme. It delivers crucial security patches until October 2026 but does not include new features or technical support. Users in the European Economic Area can register for ESU at no cost. Others can qualify by updating to the latest version of Windows 10, having a Microsoft account, and backing up their device settings.
If these steps aren’t followed, users must pay $30 (£22) or use 1,000 Microsoft Rewards points to access ESU. Businesses using Windows 10 will pay $61 per device, depending on location.
What will change after the deadline
Since launching in 2015, Windows 10 has received constant updates to fix bugs, strengthen security, and improve performance. Microsoft now wants users to transition to Windows 11. However, the new system has stricter hardware requirements and demands a Microsoft account for full access. Even those extending Windows 10 through ESU will need one. Some users have voiced privacy concerns over this condition.
Growing risks for those who delay
After 14 October, Windows 10 devices will stop receiving critical security updates. That will make them easier targets for viruses, ransomware, and other online threats. Over time, the lack of updates will weaken their defences and leave them increasingly vulnerable.
Recent cyberattacks have already hit major retailers, car manufacturers, and childcare organisations. Microsoft’s Chief Marketing Officer, Yusuf Mehdi, warns that businesses using unsupported software could face compliance and security risks. Developers may also stop supporting older systems, leading to missing features and app compatibility issues.
For millions of users, the end of Windows 10 marks a turning point. Upgrading ensures protection and stability, while staying behind could mean facing greater risks in a fast-moving digital world.
