Windows 10 Support Has Ended. Your Risk Exposure Hasn't.
Microsoft stopped patching Windows 10 on 14 October 2025. Every device still running it is operating without security updates (unless incurring additional extended support costs), right now โ a live compliance and cyber risk, not a future one. We plan and deliver enterprise-scale Windows 11 migrations that get regulated organisations current, compliant, and back in control.

Why upgrade now
Staying on Windows 10 isn't neutral โ it's an accumulating risk
Six reasons the cost of waiting keeps rising, not staying flat.
No more security patches
Windows 10 stopped receiving security updates on 14 October 2025. Every vulnerability discovered from that date on will never be fixed unless you invest in extended support โ and attackers specifically target unsupported systems because they know the flaws are permanent.
Compliance obligations tied to patch currency
GDPR, PCI-DSS, Cyber Essentials and ISO 27001 all require current security patching. An unsupported operating system is a guaranteed audit finding, not a theoretical risk.
Cyber insurance exclusions
Many cyber insurance policies now explicitly exclude claims arising from unsupported software. A breach on an unpatched Windows 10 estate can leave the full cost uninsured.
Vendor and hardware support is lapsing
Software vendors and hardware manufacturers are progressively dropping Windows 10 compatibility, meaning drivers, firmware and application updates stop arriving even outside Microsoft's own support window.
Hardware-backed security you can't retrofit
Windows 11's TPM 2.0 and Secure Boot requirements enable virtualization-based security and hypervisor-protected code integrity โ protection classes that cannot be bolted onto Windows 10 devices.
Extended Security Updates get more expensive every year
Microsoft's paid Extended Security Update programme is a temporary bridge, not a strategy โ pricing escalates annually per device for three years, making delay the most expensive option over any multi-year horizon.
Our approach
Managing Windows End of Support is a programme problem, not a desktop engineering one
A six-stage delivery model proven at 10,000โ270,000 endpoint scale in regulated industries.
Discovery & Estate Audit
Full endpoint inventory, hardware scoring, OS/patch breakdown and a compliance gap report โ typically within 3 weeks of mobilisation.
Application Compatibility
Automated scanning plus manual Tier-1 review. The remediation backlog is scoped, vendor-triaged and sequenced before migration begins.
Image & Policy Design
Windows 11 baseline, Intune/Autopilot configuration, BIOS standardisation and CIS benchmark hardening, built once and deployed consistently.
Phased Migration Waves
Risk-stratified waves โ pilot, department, remote/VIP โ with rollback capability maintained throughout every wave.
Programme Governance
Weekly SteerCo, a live RAG dashboard, an issue/risk log and board-ready reporting from week one, not week six.
Hypercare & Handover
Four weeks of hypercare after each wave, plus a full runbook and knowledge transfer so your team owns the estate going forward.
