Windows 10 End of Life in 2025: Implications for Businesses

Q: What does Windows 10's end of support mean for businesses?

After October 14, 2025 , Microsoft will stop security updates, bug fixes, and support for Windows 10. Businesses that continue using it risk cybersecurity threats, compliance issues, and software incompatibility.

Q: What are the risks of not upgrading?

- Security threats – No updates mean increased cyber risks. - Compliance issues – Outdated systems may violate industry regulations. - Software incompatibility – New applications may not support Windows 10. - Higher IT costs – Maintaining outdated systems is expensive.

Q: How should businesses prepare for Windows 10 end of life?

1. Assess infrastructure – Identify Windows 10 devices and upgrade needs. 2. Upgrade hardware – Ensure devices meet Windows 11 requirements. 3. Check software – Verify application compatibility. 4. Plan migration – Implement a phased rollout to minimise disruptions. 5. Train employees – Familiarise staff with Windows 11 features.

Q: What if hardware isn’t compatible with Windows 11?

- Upgrade components – If possible, improve system specs. - Buy new devices – Future-proof operations with Windows 11-ready hardware. - Use cloud solutions – Services like Windows 365 or Azure Virtual Desktop can extend system usability.

Q: How can businesses ensure a smooth transition to Windows 11?

- Work with an IT provider for expert migration support. - Use deployment tools like Microsoft Intune and Autopilot for automation. - Enhance security with Microsoft Defender to protect systems before and after migration. - Plan a phased rollout to minimise business disruptions.

As the 2025 deadline for Windows 10 end of life approaches, businesses must proactively manage their migration to Windows 11 to maintain operational continuity and security. With Windows 10 operating on 73% of the world’s desktops, this transition is not just a technical update but a critical business necessity.

Support for Windows 10 will officially cease on October 14, 2025. Post this date, businesses using Windows 10 will face increased risks without the safety net of Microsoft’s security patches and compliance updates. Transitioning to Windows 11 is essential to avoid these vulnerabilities and ensure Windows 10’s end of life does not disrupt business operations.

Despite the critical nature of this migration, uptake has been slow. As of December 2024, Windows 11 accounts for just 34.12% of desktop installations, compared to Windows 10’s 62.7%. This slow transition can be attributed to several migration challenges:

Challenges in Migrating to Windows 11

Hardware Requirements: Windows 11 requires TPM 2.0 and Secure Boot, which many older systems lack, making hardware upgrades necessary.
Software Compatibility: Some legacy applications may not work on Windows 11, requiring updates or replacements.
Training and Adaptation: IT teams and employees must adapt to the new system, which may temporarily impact productivity.
Cost Implications: Migration costs include new licenses, potential hardware upgrades, increased IT support, and the risk of temporary operational disruptions.

High-Level Steps for Migrating to Windows 11

Assessment and Planning: Conduct a detailed IT infrastructure assessment to determine hardware and software readiness for Windows 11.
Hardware and Software Updates: Upgrade or replace systems that do not meet Windows 11 requirements. Identify and update or replace incompatible software.
Pilot Testing: Deploy Windows 11 on a small scale to identify potential issues and training needs.
Training and Support: Implement training programs and establish a support structure for employees.
Full Deployment: Roll out Windows 11 across your organisation, ensuring continuous monitoring and optimisation.

Preparing for Windows 10 End of Support Life

With the Windows 10 end of support life deadline nearing, businesses must act to prevent security risks and disruptions. A structured migration plan ensures a smooth transition and minimises outdated system vulnerabilities.

Initiate a Technology Audit: Assess existing infrastructure to determine Windows 11 compatibility.
Develop a Migration Strategy: Create a detailed plan with timelines, resource allocation, and risk management.
Engage Stakeholders: Secure alignment and approvals from key decision-makers.
Select a Pilot Group: Test the transition with a representative group before full-scale deployment.
