In October 2025, Microsoft will officially retire support for Windows 10, marking a pivotal shift for countless organisations. Since its launch in 2015, Windows 10 has been the bedrock of modern workplaces—including both everyday devices and enterprise systems. As Microsoft embraces a future driven by enhanced security, AI integration, and cloud-native computing, it’s crucial for businesses to prepare for the next era: migrating to Windows 11 or adopting cloud-based solutions like Azure Virtual Desktop (AVD).

 

This change presents both urgency and opportunity. Let’s explore what the end of support means, your options, and how Capital Data can help you navigate this transition smoothly.

 

What Does “End of Support” Mean?

Windows 10 initially received mainstream support until October 2020, after which it entered extended support, which ends in October 2025. At that point, Microsoft will cease issuing critical security updates, patches, bug fixes, and feature enhancements—effectively marking the end of life for the operating system.

 

While Windows 10 will still function, the absence of security updates significantly raises the risk of cyber threats, especially for organisations in regulated industries or handling sensitive data. Unsupported systems quickly become targets for cybercriminal activity, and compliance auditors are unlikely to make exceptions.

 

Options for Moving Forward

1. Upgrade to Windows 11

As Microsoft’s latest OS, Windows 11 is designed for improved security, productivity, and hybrid work. Key features include:

– Enhanced security, through mandatory TPM 2.0 and Secure Boot support

– Improved performance, higher energy efficiency, and modern UX features like Snap Layouts and Microsoft Copilot integration

– Stronger multitasking and Microsoft 365 alignment

 

Considerations:

– Some older hardware may not meet Windows 11’s minimum requirements, potentially necessitating device upgrades

– Planning for user adoption and training is essential

– Ensure budgeting accounts for both licensing and any hardware refresh needs

 

2. Transition to Azure Virtual Desktop (AVD)

Azure Virtual Desktop lets you run Windows 11 in the cloud, accessible from any device—legacy or current, anywhere.

 

Key advantages:

– Eliminates hardware dependency

– Scales flexibly for hybrid and remote teams

– Centralised security and application management

– Cost-effective through pay-as-you-go usage

 

Considerations:

– Requires solid network infrastructure and identity management (e.g. Azure AD, Intune)

– User experience depends on internet quality and latency

– Licensing and Azure consumption costs need careful planning

 

3. Hybrid Strategy

A blended approach may suit many organisations best. Upgrade essential systems to Windows 11, and use AVD for contractors, remote workers, or temporary staff.

 

Benefits include:

– Prolonging the life of existing hardware

– Phasing into cloud environments gradually

– Aligning IT strategy with business growth and flexibility needs

 

4. Extended Security Updates (ESU)

For organisations that cannot transition immediately, Microsoft’s Extended Security Update program offers additional security patch coverage for up to three years post-support—available at a premium.

– Pros: Keeps Windows 10 systems secure temporarily, with no minimum purchase

– Cons: Limited to Windows 10 version 22H2 and costs start at approximately $90 per device in the first year—doubling annually thereafter

 

What Happens If You Don’t Take Action?

Delaying migration poses significant risks:

– Increased cybersecurity threats, including ransomware and zero-day vulnerabilities

– Non-compliance with standards like ISO 27001, Cyber Essentials, or industry-specific mandates

– Operational inefficiencies due to software incompatibility

– Support challenges when vendors phase out Windows 10 compatibility

 

Planning Your Migration

To make the transition seamless, follow a structured roadmap:

– Assess your environment: Inventory all Windows 10 machines and check compatibility with Windows 11

– Choose your strategy: Evaluate whether to go with local upgrades, cloud desktops, or a hybrid model

– Engage support partners: Decide if you’ll manage internally or seek expert assistance

– Segment user groups: Identify who should transition to which environment

– Review licensing: Understand implications for Microsoft 365, Windows 11, and AVD

– Pilot and test: Run small rollouts with select users

– Train your teams: Prepare guidance, FAQs, and support materials

– Optimise and scale: Automate deployment and expand in phases
