Windows 10 End of Life: How to Navigate the Transition

June 23, 2025

With Microsoft's Windows 10 support ending on 14th October 2025, organisations across the UK face a critical decision point that could impact their security, productivity, and operational continuity. Recent reports suggest that over 400 million Windows 10 users globally—including millions of UK businesses—must act now to avoid significant cybersecurity risks.

The Scale of the Challenge

The statistics are sobering. Microsoft has confirmed that Windows 10 PCs approaching end of support may be automatically upgraded to Windows 11, whether organisations are ready or not. However, analysts estimate that at least 240 million PCs worldwide cannot support the free upgrade due to hardware limitations, leaving organisations with three options:

  • Upgrade to new hardware that supports Windows 11
  • Pay Microsoft $30  (USD) per device for a 12-month security extension (a temporary measure at best)
  • Accept the cybersecurity risks of running unsupported systems

For UK organisations, particularly those in the financial services and public sector where Altiatech specialises, the third option simply isn't viable given regulatory compliance requirements.


More Than Just an Operating System Upgrade

What many organisations fail to recognise is that this transition represents far more than a simple OS upgrade. It's an opportunity to fundamentally transform how your workforce operates whilst strengthening your cybersecurity posture. The shift to Windows 11 brings with it enhanced security features, improved collaboration tools, and the foundation for implementing Zero Trust security models.

However, without proper planning and expertise, this transition can become a costly disruption that impacts productivity and introduces new vulnerabilities.



How Altiatech Can Transform Your Windows Migration

At Altiatech, we've been helping organisations navigate complex technology transitions since 2013. Our approach to Windows 10 end of life goes beyond simple hardware replacement—we see this as your gateway to a more secure, efficient, and future-ready digital workplace.




Strategic Assessment and Planning

Our Cloud Centre of Excellence team begins with a comprehensive assessment of your current infrastructure. We evaluate not just which devices need upgrading, but how this transition can align with your broader digital transformation goals. This includes:

  • Hardware compatibility audits across your entire estate
  • Application compatibility testing to ensure business continuity
  • Security gap analysis to identify improvement opportunities
  • Cost-benefit analysis comparing upgrade paths with our expert guidance



Modern Workspace Solutions

Rather than simply replacing old devices with new ones, we design modern workspace solutions that enhance productivity and collaboration. Our cutting-edge Modern Workspace offerings include:

  • Device management strategies that simplify IT administration
  • Hybrid working enablement with secure remote access capabilities
  • Collaboration technology integration including Microsoft Teams optimisation
  • Audiovisual solutions for enhanced meeting room experiences


Cybersecurity Integration

The Windows 11 transition provides an ideal opportunity to implement comprehensive cybersecurity improvements. We ensure your new environment incorporates:

  • Zero Trust security models that verify every access request
  • Identity and Access Management solutions that control who accesses what
  • Multi-factor authentication implementation across all systems
  • Conditional access policies that adapt to risk levels in real-time


Change Management Excellence

Technology transitions fail when organisations focus solely on the technical aspects whilst neglecting the human element. Our approach includes comprehensive change management support:

  • User training programmes tailored to your organisation's needs
  • Phased rollout strategies that minimise disruption
  • 24/7 support during the transition period
  • Documentation and knowledge transfer to empower your internal teams


Taking Action: Your Next Steps

With fewer than 120 days until Windows 10 support ends, time is of the essence. However, rushing into decisions without proper planning often leads to costly mistakes and security vulnerabilities.

Immediate Actions:

  1. Audit your current estate to understand the scope of the challenge
  2. Engage with experts who understand both the technical and business implications
  3. Develop a strategic plan that aligns with your organisation's objectives
  4. Begin procurement processes for any new hardware or software requirements

Strategic Considerations:

  • How can this transition support your broader digital transformation goals?
  • What cybersecurity improvements can be implemented alongside the upgrade?
  • How will you maintain productivity during the transition period?
  • What training and support will your teams need?

Secure Your Digital Future

The Windows 10 end of life deadline isn't just a technology challenge—it's an opportunity to secure your organisation's digital future. With proper planning, expert guidance, and strategic implementation, this transition can strengthen your cybersecurity posture, enhance productivity, and position your organisation for continued success.

Don't wait until the last minute. Contact Altiatech today to begin your strategic planning process and ensure your organisation is ready for the post-Windows 10 world.

Cyberattacks, system failures, natural disasters, and human errors will occur—the question isn't if but when. Cyber resilience planning ensures organisations can withstand incidents, maintain critical operations during disruptions, and recover quickly when systems fail. It's not just about preventing attacks; it's about ensuring business continuity regardless of what goes wrong.

Manual user provisioning - the process of creating accounts and granting access through email requests and IT tickets - seems manageable for small organisations. As organisations grow, this approach creates mounting security risks, operational inefficiencies, and frustrated users waiting days for access they need immediately.

Multi-cloud strategies deliver flexibility, redundancy, and the ability to select the best platform for each workload. They also create complex security challenges, particularly around identity and access management. Each cloud provider offers different security models, tools, and terminology, making unified security difficult to achieve.

Privileged accounts—those with administrative rights to critical systems—represent the most attractive target for attackers. A single compromised privileged credential gives attackers complete control over infrastructure, data, and operations. Yet many organisations manage privileged access inadequately, creating unnecessary risk.

Identity and access management represents a critical security capability, yet many organisations struggle to assess whether their IAM implementation is truly effective. Identity governance maturity models provide a framework for evaluation, revealing gaps and priorities for improvement.

Traditional security models assumed everything inside the corporate network was trustworthy, focusing defensive efforts on the perimeter. This approach fails catastrophically in today's hybrid work environment where employees access resources from homes, coffee shops, and co-working spaces whilst applications reside across multiple clouds.
