With Microsoft ending support for Windows 10 on 14 October 2025, UK businesses are at a crossroads. Continuing to use Windows 10 will leave organisations exposed to cyber threats, compliance risks, and operational disruptions. Over half of UK businesses are still running Windows 10, yet many lack a clear migration plan.
After the deadline, Microsoft will stop providing free security updates, bug fixes, and technical support for Windows 10. While Extended Security Updates (ESU) will be available for a fee, this is only a temporary measure and not a sustainable long-term solution for most firms. Unsupported systems are prime targets for cybercriminals: the UK Government’s Cyber Security Breaches Survey 2024 found that around 50% of businesses experienced a cyber incident in the past year. Without regular updates, every new vulnerability becomes an open door for hackers.
Windows 11 offers advanced security features, including hardware-level protections and enhanced ransomware defences, which Windows 10 cannot match. Upgrading ensures ongoing protection, compliance with industry regulations, and compatibility with the latest business software.
The message is clear: UK businesses must act now to develop and implement a migration plan to Windows 11. Delaying increases the risk of costly downtime, data breaches, and reputational damage. Future-proofing operations by upgrading is not just best practice—it’s essential for business continuity and security in today’s threat landscape
