Covering the full range of enterprise Microsoft products including SQL Server, Windows Server, Azure, Dynamics 365, and Dynamics AX, whether on premises, in the cloud, or across hybrid environments, Zaco Computers UK Limited helps you eliminate traditional support inefficiencies while keeping your business running smoothly, efficiently, and under full control.

Why UK Enterprises Are Reconsidering Their Microsoft Support Model

Around 72% of IT leaders are actively evaluating alternatives to vendor support models, with cost and response quality cited as the primary drivers.

Microsoft Unified Support costs are projected to increase by around 9% year on year through to 2027. Priced as a percentage of your total Microsoft spend, costs rise automatically as your environment grows, regardless of whether your support usage does.

What Zaco Delivers Across Your Microsoft Infrastructure

Each service area addresses a distinct operational requirement β€” from live incident resolution to long-term infrastructure planning.

Break / Fix Incident Resolution

Diagnosis and resolution of incidents across the Microsoft server and infrastructure stack. Engineers hold hands-on expertise across on-premises, hybrid, and Azure-connected environments. Production environments and business-critical databases carry the highest response priority under SLAs agreed during onboarding.

Technology Advisory and Migration Planning

An objective assessment of your Windows Server, SQL Server, and connected Microsoft infrastructure. We evaluate the case for maintaining current systems under managed IT services cover, upgrading in place, or migrating toward Azure managed services. Recommendations are based on your operational requirements and cost position β€” not on a vendor's upgrade roadmap.

Microsoft Managed Services

Administration, configuration, and integration support for Microsoft environments, covering identity, connectivity, and access β€” the layers most likely to generate real-world incidents. Integration with on-premises Active Directory and ADFS is within scope.

Azure Infrastructure and Hybrid Environments

Support for Azure-hosted workloads, Azure DevOps, and hybrid on-premises-to-Azure configurations. Mixed environments running some components on-premises and others in Azure are fully within scope, including ongoing management of the connectivity.

FAQs

Frequently Asked Questions

1. Can we keep using our current Microsoft software without upgrading?
- Yes. If your current Microsoft environment is stable and meets your operational needs, upgrading solely to satisfy a vendor support lifecycle is not justified. Zaco extends support for your existing software, improving ROI without a forced migration.
2. Can we choose support for only specific Microsoft products or systems?
- Yes. Support can be scoped to the specific Microsoft products or systems your organisation needs covered. You are not required to take a blanket contract across your entire Microsoft estate.
3. What happens if Microsoft discontinues support for a product?
- When Microsoft discontinues support, the software continues to work but stops receiving security patches, non-security updates, and technical assistance. For most organisations, this creates pressure to upgrade immediately, often at significant cost and disruption, regardless of whether the existing system is meeting business needs.
This is where a third party support provider like Zaco comes in. We continue supporting your Microsoft environment beyond the vendor end-of-life date, maintaining performance, and stability on your terms. You upgrade when your business is ready, not because a vendor deadline forces it.
4. How much will a UK organisation save by switching to Zaco Microsoft third party support?
- UK organisations can save up to 30 to 50% on annual Microsoft IT support costs, depending on their environment, with Zaco's fixed-rate model that does not increase as your Microsoft footprint grows.
5. Does switching to third party support affect our Microsoft licences?
- No. Microsoft licence agreements remain unchanged. Third party support replaces only the support and maintenance contract, not the underlying software entitlements.
6. Which Microsoft products does Zaco support in the UK?
- Zaco provides third party support across SQL Server (all editions from 2008 onwards), Windows Server including versions approaching end-of-life such as Windows Server 2012 R2, Microsoft Azure, Dynamics 365, and Dynamics AX environments.
7. How do we migrate from Microsoft Unified Support to your services?
- The transition is straightforward. Reach out to us at info@zacocomputer.com and we will walk you through the process, provide a cost comparison against your current Unified Support contract, and outline the SLA options available. Once your contract is in place, we onboard your environment, assign a dedicated engineer, and take over support with no gap in coverage.
8. Do you provide proactive guidance for future upgrades or migrations?
- Yes. Beyond resolving issues, our expert team advises on upgrade timelines, migration planning, and infrastructure decisions, so you can move when it makes business sense, not when a vendor deadline forces it.
