What unsupported software does to Cyber Essentials and ISO 27001 after Windows Server 2016 end of support — the rules each scheme applies, whether ESU keeps you compliant, how segregation and scoping really work, the evidence assessors ask for, and a 150-day plan to fix it before January 2027.
A five-step Windows Server 2016 upgrade assessment: build a real inventory, check hardware against Windows Server 2025, chase application certifications, audit Active Directory prerequisites and price every route — then score each server into go, fix, re-route or defer verdicts.
What Windows Server 2016 Extended Security Updates really cost year by year, why the free-in-Azure route ended in April 2026, and a workload-by-workload framework for choosing between paying for ESU, upgrading to Windows Server 2025 and rehosting in Azure.
Why one jump to Windows Server 2025 beats a two-step upgrade, how the in-place and clean-install routes compare, the CPU and licensing checks that catch teams out, what the project really costs, and a cutover-weekend runbook that lands before the January 2027 deadline.
What the 12 January 2027 deadline actually changes, why it is a board-level risk for UK businesses, how upgrading in place, migrating to Azure, buying Extended Security Updates and replacing workloads with SaaS compare on cost, and a five-month plan that finishes before the change freeze.
