# Windows 10 business migration after end of support: what to do next Published by Britixo | 2026-10-29 | Security & Microsoft 365 Canonical page: https://britixo.com/business-guides/windows-10-business-migration/ Inventory the exact Windows editions and hardware, identify business-critical applications, then place each device on an upgrade, replacement or approved temporary-support path. Windows 10 version 22H2 reached normal end of support on 14 October 2025. Commercial Extended Security Updates may provide a limited bridge for eligible enrolled devices, but they do not replace a migration plan. Check edition-specific lifecycles, eligibility and current terms before making the decision. ## When this guide is useful Businesses still operating Windows 10 devices and planning supported replacements or upgrades - Staff still use Windows 10 but there is no device-by-device support plan. - An essential application or peripheral blocks a straightforward upgrade. - Different offices are replacing equipment without a shared configuration standard. - Management has assumed antivirus updates or an ESU purchase cover every support need. ## Separate lifecycle facts from assumptions Record the operating-system edition, version and build for every business device, along with processor, memory, storage and hardware eligibility. Microsoft's lifecycle notice covers Windows 10 22H2 and specified older editions; specialist LTSC, LTSB or IoT releases need their own lifecycle check. Do not assign one support date to every device carrying the Windows 10 name. Microsoft's commercial ESU documentation describes eligible 22H2 devices receiving critical and important security updates for a maximum of three years after end of support. It excludes new features and general product support. Confirm enrolment, activation, required servicing prerequisites and current commercial terms for the actual devices; consumer arrangements are a different programme. ## Test the workflows that could stop the business Choose representative users and test the complete task they perform, not merely whether an application opens. Include document templates, accounting exports, printers, scanners, specialist drivers, browser extensions and remote-access software. Ask application vendors for their supported Windows versions and keep that evidence with the migration record. Create an exception register for anything that cannot move immediately. Describe the business dependency, owner, support position, compensating controls and intended replacement date. An old peripheral may be cheaper to replace than maintaining a separate operating-system exception, but that decision should include the cost of disruption and retraining. ## Prepare a repeatable deployment and user handover Define the approved device configuration, application set, identity join, encryption, management enrolment and support route. Validate the user's files and required settings under your agreed migration and recovery process. Make the change sequence explicit so an engineer can tell whether a missing application is expected or a deployment failure. Use phased deployment groups based on operational risk and application similarity. Give staff clear instructions about the maintenance window, first sign-in and where to report issues. Avoid scheduling the finance team during a close or a customer-service group during peak demand. Record the acceptance result before treating a device as complete. ## Close exceptions and prove the supported state After each phase, check that devices report into management, receive the intended updates and can perform the agreed workflows. Compare the live inventory with the migration list to catch forgotten remote equipment and spare machines. A completed purchase order is not evidence that every endpoint has changed. For temporary ESU devices, monitor update receipt and keep the migration deadline visible. Retire or repurpose old equipment through an authorised process that protects company information and honours retention requirements. Review lessons from support tickets and improve the deployment instructions before the next group, rather than repeating the same avoidable interruption. ## Prepare for a useful conversation - Exact edition, version and hardware inventory for every in-scope endpoint. - Vendor support evidence and business-workflow test results. - A per-device upgrade, replacement or time-limited exception decision. - An approved deployment, data-handling and user-acceptance procedure. - Post-change management, update and application checks with named owners. ## How Britixo can help Britixo can help assess your Windows estate, identify compatibility blockers and organise a phased migration with your internal staff or device suppliers. A project can include an inventory, pilot, standard configuration, application validation and user handover. Where a legacy application is the obstacle, we can examine integration, replacement or modernisation options as a separate workstream. Contact Britixo with your approximate device count, current editions and critical applications. Hardware, Microsoft licensing, ESU eligibility, deployment tooling and support coverage are confirmed for your circumstances; no single support arrangement should be assumed to cover every device.

The device may continue to operate, but normal support ending changes its servicing and risk position. The decision is about supported operation, not whether it can still boot. ### Does commercial ESU include new features and normal support? No. Microsoft's programme is limited in scope. Check its current terms, eligibility and servicing requirements, and keep a separate migration plan. ### Should every Windows 10 computer be replaced? Not necessarily. Some devices can move to a supported operating system and meet the business workload. Others need replacement because of hardware eligibility, reliability or application needs. ## Related guides - [Employee onboarding and offboarding: close the access gaps](https://britixo.com/business-guides/employee-onboarding-offboarding-access/) - [How to roll out phishing-resistant MFA without locking out your team](https://britixo.com/business-guides/phishing-resistant-mfa-rollout/) - [Review a SaaS supplier's security with evidence, not a checkbox](https://britixo.com/business-guides/saas-supplier-security-review/) ## Sources and further reading - [Microsoft: Windows 10 end of support](https://learn.microsoft.com/en-us/lifecycle/announcements/windows-10-end-of-support) - [Microsoft: Commercial Windows 10 ESU programme](https://learn.microsoft.com/en-us/windows/whats-new/extended-security-updates) Prepared with AI assistance and checked against linked primary documentation.
