Windows 10 End of Support: 14 October 2025. No more security patches. Ransomware risk. Cyber insurance invalidation. Act now.
Coreitech manages end-to-end Windows 11 migrations for London and UK businesses — hardware readiness assessment, application compatibility testing, phased rollout, and device procurement where required. Fixed price. Zero working-hours downtime.
Many pre-2019 business PCs will fail these requirements. A hardware audit is essential.
Migration process —
how Coreitech does it
Free Readiness Assessment
We scan every device and identify which are Windows 11 compatible, which need firmware updates, and which require replacement. Full report provided.
Application Compatibility
We test your critical business software on Windows 11 before touching any user devices. Line-of-business apps, peripherals, and specialist software all verified.
Phased Rollout
Pilot group first, then department-by-department. Weekend migrations for servers and shared systems. Users return Monday to fully migrated, tested devices.
Device Procurement
Where hardware replacement is needed, we procure, configure, and deploy business-grade devices. Old hardware securely disposed of with NCSC-certified ITAD.

common questions
Q.When does Windows 10 end of support?
Microsoft Windows 10 reaches end of support on 14 October 2025. After this date, Microsoft will no longer provide security updates, bug fixes, or technical support for Windows 10. Businesses still running Windows 10 after this date face significant security risks — unpatched vulnerabilities will be exploited by attackers, and cyber insurance policies may be invalidated by running unsupported OS versions.
Q.Do all PCs support Windows 11?
No. Windows 11 has strict hardware requirements — most critically, a TPM 2.0 chip and a compatible 8th-generation Intel or Zen+ AMD processor or newer. Many business laptops and desktops purchased before 2019 will not meet these requirements and cannot be upgraded to Windows 11. A hardware audit is essential before planning migration. Coreitech performs free Windows 11 readiness assessments for London and UK businesses.
Q.How long does a Windows 11 migration take for a business?
A typical SME migration (10–50 users) takes 2–6 weeks depending on hardware compatibility, application testing requirements, and whether new devices need to be procured. Coreitech runs migrations in phases — hardware audit, application compatibility testing, pilot group rollout, then full deployment — minimising disruption. We can typically complete migrations over weekends to avoid working-hours impact.
Q.What happens if we don't migrate from Windows 10?
Running Windows 10 after October 2025 without Extended Security Updates (ESU) means: no security patches, increasing vulnerability to ransomware and malware, potential cyber insurance invalidation (most policies require supported OS), and likely compliance issues (GDPR requires appropriate technical measures — running unsupported software undermines this). Microsoft's Extended Security Updates programme offers a paid extension (£25–50/device/year) but is not a long-term solution.
Q.How much does Windows 11 migration cost for a business?
Windows 11 migration costs depend on hardware compatibility. If all devices are compatible: typically £50–150/device for migration labour (imaging, configuration, application testing). If hardware replacement is required: add £400–800/device for business-grade laptops. Coreitech provides fixed-price Windows 11 migration quotes following a free readiness assessment — for Coreitech managed IT clients, migration is included in the monthly fee.
