Microsoft has officially confirmed that support for Windows 10 will end on October 14th, 2025.
What does this mean for you?
After this date, Windows 10 will no longer receive any updates, including critical security patches and feature enhancements. While the operating system will technically continue to function, it will be considered obsolete and increasingly insecure.
Additionally, major software providers such as Google (Chrome) and Adobe (Reader) are expected to phase out support for Windows 10. This means their applications may no longer be updated or even installable on unsupported devices, introducing further operational and security risks.
Under GDPR legislation and Cyber Essentials guidance, all operating systems in use must be fully up to date and capable of receiving security updates. This is a fundamental requirement for maintaining a secure IT environment and protecting personal and business-critical data.
In our professional opinion, continuing to use Windows 10 after October 14th, 2025 will be non-compliant with both GDPR and Cyber Essentials requirements. The operating system will be classified as unsupported and insecure, significantly increasing the risk of exploitation.
In the event of a cyber attack or data security breach, the Information Commissioner’s Office (ICO) is likely to assess whether your organisation took appropriate measures to protect personal data. Operating outdated or unsupported software would be viewed as a failure to implement adequate technical controls, which could lead to regulatory action, including fines.
What can you do?
The current Microsoft operating system is Windows 11. In some cases, it is possible to upgrade an existing Windows 10 computer to Windows 11, but this is subject to certain hardware compatibility requirements, including:
- Minimum RAM capacity
- Supported CPU/processor model
- Presence of a TPM 2.0 security chip
- Overall hardware age and specification
As a general rule, if your computer has been displaying messages inviting you to upgrade to Windows 11, it is likely to be compatible. In such cases, the upgrade is typically free of charge.
However, if your system is not compatible, the only viable option is to replace the device with a new desktop or laptop that meets the current requirements.
Summary
- Windows 10 becomes unsupported on October 14th, 2025.
- You may be able to pay approximately £60.00 per year per device for extended security updates only (via Microsoft’s ESU programme).
- However, third-party applications such as web browsers, antivirus software, and business tools will begin to withdraw support for Windows 10.
- Most IT support providers, including QLine IT, will cease support for Windows 10 systems after the cut-off date due to the associated security and compliance risks.
We strongly advise all clients to plan ahead and ensure their systems are fully supported and compliant well before October 2025.
