It’s time to Prepare for the End of Support for Windows 10

Microsoft is withdrawing support for Windows 10, which will take effect on October 14th 2025. This means that Microsoft will no longer provide technical support, software patches, or support for Microsoft 365 apps on devices running Windows 10. While it is still possible to use these devices after the October deadline, continuing to do so could leave you increasingly vulnerable to security risks and malware.

The questions and answers below take a look at the implications this has for your business and discuss how Greenlight can help you update to a more secure and efficient operating system.

What does “end of support” mean for Windows 10 for my business?

After the 14th October 2025, Microsoft will no longer provide free security updates, non-security updates, or assisted support for Windows 10. This will leave your systems vulnerable to cyber attacks, potentially leading to data breaches, compliance issues, and operational disruptions. Continuing to use Windows 10 after this date is viewed as a failure to mitigate risks and could result in your cyber insurer denying coverage claims.

When does Windows 10 reach its end of support?

The official end of support date for Windows 10 is 14 October 2025. After this date, your business will no longer receive support updates.

What happens to your business PCs after the end of support date?

Your Windows 10 devices will continue to function, but they will face a heightened risk of viruses and malware due to the absence of security updates. Additionally, you may encounter compatibility issues with new software and hardware, along with potential operational challenges and disruptions.

What are your business’s options after Windows 10 reaches end of support?

• Upgrade to Windows 11: This is the simplest option for organisations already within the Microsoft ecosystem. Windows 11 provides enhanced security features, including TPM 2.0 and Secure Boot.
• Purchase new computers equipped with Windows 11: New computers are designed to utilise the latest features, providing improved battery life and managing demanding tasks.
• Enroll in Microsoft’s Extended Security Updates (ESU) programme (for eligible editions): ESUs offer security updates for up to three years following the EOL date.
• Consider alternative operating systems: A switch to Linux might be a viable option, offering cost savings, customisation, and control. However, compatibility with existing software needs to be considered.

What are Extended Security Updates (ESUs) and are they right for your business?

ESUs are a paid programme that offers security updates for up to three years following the EOL date for specific editions of Windows 10. While ESUs can assist in maintaining compliance and security, they are a short-term solution, and the costs increase each year.
