Preparing Your Organisation for the Windows 11 Migration: A Strategic IT Priority for 2025

July 24, 2025

Why British businesses must act now to avoid the October 2025 Windows 10 end-of-life deadline

With Windows 10's end-of-life date fast approaching on 14 October 2025, organisations across the UK face a critical decision point. Despite Windows 10's continued popularity and seemingly modern interface, this decade-old operating system will soon join the ranks of legacy technologies like Internet Explorer, leaving users vulnerable to significant security risks.


The Urgency Behind the Upgrade

Many organisations remain hesitant about migrating to Windows 11, often because Windows 10 simply "works" for their current needs. However, this comfort with the status quo could prove costly. The security implications of running unsupported software are substantial, as history has repeatedly demonstrated.

We've witnessed the consequences of delayed upgrades before. When Windows XP support ended in April 2014, vulnerabilities in Internet Explorer 6-11 were quickly exploited by cybercriminals. More dramatically, the 2017 WannaCry ransomware attack devastated organisations worldwide by exploiting unpatched XP systems, causing billions in damages and disrupting critical services including NHS operations.


Understanding Windows 11's Hardware Requirements

One significant barrier preventing organisations from upgrading is Windows 11's enhanced hardware requirements. Unlike previous Windows upgrades, Windows 11 mandates specific security-focused hardware features:

  • TPM 2.0 (Trusted Platform Module) - Essential for hardware-based security functions
  • UEFI firmware - Replacing legacy BIOS systems
  • Secure Boot capability - Preventing malicious software from loading during startup

These requirements aren't arbitrary obstacles—they're fundamental security enhancements that make Windows 11 significantly more secure than its predecessor.


Enhanced Security Through Modern Hardware

Windows 11's hardware requirements enable robust security features that were optional or unavailable in Windows 10.
These include:

Secure-by-Default Architecture: Features like BitLocker encryption, Virtualisation-Based Security (VBS), and Secure Launch are now enabled automatically, rather than requiring manual configuration.

Advanced Authentication: Native passkey management and improvements to Windows Hello provide stronger, more convenient authentication methods.

Enhanced Threat Protection: Features like Credential Guard now operate with improved default behaviours, providing better protection against credential theft attacks.


The Business Case for Migration

Organisations facing hardware upgrades to meet Windows 11 requirements should view this as a strategic security investment rather than an unwelcome expense. Modern hardware not only supports Windows 11's enhanced security features but also provides:

  • Improved performance and energy efficiency
  • Better support for hybrid working environments
  • Enhanced compatibility with cloud-based services
  • Reduced long-term maintenance costs


Planning Your Migration Strategy

Successful Windows 11 migration requires careful planning and expert guidance. Consider these key steps:

Asset Assessment: Conduct a comprehensive audit of your current hardware to identify devices that meet Windows 11 requirements and those requiring replacement.

Security Evaluation: Review your current security posture and identify how Windows 11's enhanced features can strengthen your defences.

Migration Timeline: Develop a phased approach that minimises business disruption while ensuring completion before the October deadline.

User Training: Prepare your workforce for the transition with appropriate training and support resources.


The Cost of Inaction

Delaying migration beyond October 2025 exposes organisations to significant risks:

  • Security vulnerabilities from unsupported operating systems
  • Compliance issues in regulated industries
  • Increased cyber insurance premiums for organisations running legacy systems
  • Operational disruption from potential security incidents

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.
