Microsoft has concluded support for Windows 10, with over 44% of PC users still operating on the OS. This poses potential risks for users, particularly as the end-of-support deadline approaches on October 14, 2025, when Microsoft will stop issuing free updates, increasing vulnerability to cyber threats. Microsoft has introduced the Extended Security Updates (ESU) program, offering security patches until October 13, 2026, at a cost of £22 for individual users and starting at £45 for businesses, with prices doubling in subsequent years. Users can also access ESU benefits through Microsoft Rewards Points or by performing a Windows Backup via OneDrive, which has a 5GB free limit. Research suggests that around 5 million individuals in the UK could be at risk due to continued reliance on Windows 10. The ESU program is available for users with Windows 10 devices running version 22H2.
