Windows 10 End of Life: How Hotfix Keeps You Supported

As of today, 14 October 2025, Microsoft has begun the final countdown to Windows 10 reaching end of life (EOL) support. On 14 October 2025, mainstream security updates, patches, and technical assistance for most editions of Windows 10 will cease. Organisations that delay migration face a growing risk surface—unpatched vulnerabilities, incompatible software, and the potential for compliance penalties.

What Windows 10 End of Life Means for Your Business

When an operating system reaches EOL, Microsoft no longer issues the monthly security updates that keep known threats at bay. Critical line-of-business applications may also stop receiving certification against Windows 10, creating reliability issues or disrupting operations altogether. Regulated industries must pay particular attention: operating on unsupported software can violate cyber security frameworks and industry mandates.

Microsoft has introduced the Extended Security Updates (ESU) programme as a stopgap, but it comes at a premium and only buys time. ESUs provide security fixes without adding new features, and the costs climb each year. For complex environments the price of standing still quickly rivals the cost of a strategic migration to Windows 11 or a managed virtual desktop service.

How Hotfix Helps Clients Navigate the Transition

Hotfix partners with organisations at every stage of their modernisation journey:

1. Executive-ready assessments. We inventory hardware, critical applications, and identity dependencies to prioritise workloads that need immediate attention. Our reports map risks to business outcomes so stakeholders can make informed investment decisions.
2. Modern endpoint roadmaps. From Windows 11 upgrades to Azure Virtual Desktop or Windows 365 adoption, we design migration paths that align with your security baseline and operational realities.
3. Automation-led deployment. Leveraging Microsoft Intune, Autopilot, and configuration-as-code practices, our engineers streamline device provisioning and cut over users with minimal downtime.
4. Ongoing managed services. Post-migration, we provide 24/7 monitoring, patch orchestration, and proactive threat hunting to keep your estate protected.

Recommended Next Steps

• Book a readiness review. Our consultants can evaluate your environment against the Windows 11 hardware compatibility list and identify devices that require replacement or alternative hosting.
• Pilot critical workloads now. Early pilot groups surface application blockers while you still have runway to remediate them.
• Plan the change communications. Clear messaging, training assets, and staged rollouts help end users embrace the new experience.

The retirement of Windows 10 is more than a technical milestone, it is an opportunity to modernise your workplace, strengthen cyber resilience, and streamline device management. Reach out to Hotfix today to build a migration plan that keeps your teams productive, secure, and compliant long after Windows 10 fades from the update cycle.
