Reliable Third-party support for Microsoft products

Microsoft Third-Party Software Support Solution

Stop Overpaying & Reduce Costs up-to 50% with end-to-end managed support across the entire Microsoft platform !

Microsoft Lifecycle Pressures and Rising Support Gaps

Microsoft support for software products follows a fixed lifecycle. Once a version reaches end-of-life, official patches, security updates, and direct Microsoft IT support cease entirely. Organisations are then expected to upgrade — regardless of whether their current environment is stable and meeting operational needs.

THE MICROSOFT SUPPORT LANDSCAPE

Why Organisations Are Reconsidering Their Microsoft Support Costs

Microsoft Unified Support, and the replacement for the now-retired Premier Support, is priced as a percentage of your total annual Microsoft spend. Every time Azure consumption grows, a new Microsoft 365 seat is added, or a Dynamics 365 module is deployed, the Unified Support baseline rises automatically at renewal.

Zaco Computers, an established IT infrastructure solutions provider specialising in Microsoft managed services, that decouple the support relationship from the OEM lifecycle and the OEM pricing model. Organisations receive expert Microsoft IT support scoped to their actual environment, covering EOL and current versions, with SLAs defined by system criticality rather than billing tier.

Third-party support models for enterprise software have been operating at scale globally since the mid-2000s. The same model now applies across Microsoft infrastructure: organisations that evaluate the alternative often find that independent Microsoft third party support delivers faster incident resolution at materially lower annual cost.

$50,000
Minimum annual cost for Microsoft Unified Support Core tier, regardless of how much support is actually consumed. The Advanced tier has a minimum contract price of $50,000 (as on 25/02/2026).

Four Microsoft-Specific Situations Where Independent Support Provides Immediate Value

📅

End-of-Life Environments Running in Production

When Microsoft's EOL date passes, all OEM support and patching stops instantly. A structured infrastructure migration takes months; the EOL date does not wait.

📈

Unified Support Costs That Rise With Every Cloud Addition

Unified Support is priced as a percentage of total Microsoft expenditure. Every new Azure workload, every additional Microsoft 365 licence, every Dynamics 365 deployment automatically increases the Unified Support baseline at renewal, independent of whether support incident volume changes. Premier Support, which had per-hour pricing, no longer exists for most organisations.

🔀

Premier Support Is Now Retired

Microsoft formally ended Premier Support for commercial organisations as of July 2022, and for public sector organisations as of July 2024. Premier offered per-hour billing and named Technical Account Managers. Unified Support, its replacement, operates on a percentage-of-spend model with higher baseline costs and fixed-tier service structures that many organisations find less suited to their actual support patterns.

🧩

Multi-Version Environments With Mixed Lifecycle Status

Most enterprise Microsoft environments run multiple product versions at the same time, some within active OEM lifecycle, some at or past EOL, some in hybrid cloud configurations. Paying a Unified Support percentage across the full Microsoft spend when only certain sql server support services or specific Windows Server versions need active incident cover is rarely cost-efficient for the organisation.

WHAT WE DELIVER

Core Microsoft IT Support Services

Each service addresses a distinct requirement: resolving live incidents, maintaining security posture in EOL environments, and providing objective guidance on whether to continue, upgrade, or migrate.

🔧 Break / Fix Incident Resolution

Diagnosis and resolution of incidents across Windows Server, SQL Server, Active Directory, Hyper-V, IIS, and connected Microsoft infrastructure. Engineers hold hands-on expertise across the full Microsoft server and infrastructure stack, covering on-premises, hybrid, and Azure-connected environments.
Response and resolution times are governed by SLAs agreed during onboarding. Production environments and business-critical databases carry the highest response priority.

📋 Technology Advisory & Migration Planning

A Microsoft EOL date is a commercial decision by the vendor, not an operational mandate for your organisation. Many enterprises run stable Microsoft environments that do not require immediate infrastructure replacement. Our advisory service provides the objective technical assessment to evaluate that determination correctly.
We review your Windows Server, SQL Server, and connected Microsoft infrastructure, then advise on options: continue with managed IT services cover, upgrade in place, or migrate toward azure managed services or a newer infrastructure platform.

COVERAGE

Microsoft Server & Infrastructure Components We Support

Our microsoft third party support covers 16 Microsoft server, identity, database, remote access, and cloud infrastructure components, spanning end-of-life product versions through to current supported releases.
Coverage scope is confirmed during onboarding based on your actual deployed environment. No fixed-tier product bundles. You define which systems require active cover; SLAs are matched to each system's operational criticality.
Both on-premises environments and hybrid on-premises-to-Azure configurations are within scope. Our microsoft 365 managed services and Azure DevOps coverage extends the service to cloud-connected components as well.

How Microsoft's Fixed Lifecycle Policy Works, and Where the Support Gap Occurs

Mainstream Support
(Years 1-5)

Full OEM Coverage

New feature development, security updates, design changes, and free incident support. Microsoft is fully engaged during this phase.

Extended Support
(Years 6-10)

Security Patches Only

Security patches and paid incident support only. No new features or design changes. Many enterprises are still running these versions when the EOL date arrives.

End-of-Life
(All OEM Support Stops)

Support Gap Emerges

All Microsoft patches and technical support cease. ESUs available for up to 3 further years, critical security patches only, no incident support or bug fixes. Windows Server 2012 R2, SQL Server 2012, and SQL Server 2014 are at this stage.

Zaco Support
(All Lifecycle Stages)

Continuous Coverage

Full break/fix incident resolution, and migration advisory across all lifecycle stages, including well past Microsoft's official EOL. No forced version changes, no product restrictions.

HOW WE ENGAGE

Two Engagement Models, Built Around Your Operations

No two Microsoft environments share the same version mix, criticality profile, or support history. Choose the model that reflects your actual requirements, or use both for different system tiers.

Annual Managed Services

Continuous Microsoft Managed Services

An annual engagement delivering ongoing Microsoft managed services, designed for organisations that require predictable cost, proactive monitoring, and a structured support relationship across their Microsoft infrastructure.

  • Custom SLAs per system tier, defined by production criticality
  • 24×7×365 service desk service included
  • Quarterly environment health reviews and infrastructure capacity planning
  • Microsoft licence procurement, including new and renewal Microsoft third party license options where genuinely required, with no surprise true‑up billing
  • Compliance documentation and audit trail records for regulated environments

On-Call Support

As-Needed Microsoft IT Support

On-call Microsoft support services help organisations that need expert technical assistance when incidents occur, without committing to a standing annual managed IT services agreement.

  • Engineer access on a per-incident or per-project basis
  • Response SLAs agreed at engagement initiation
  • Suited to stable environments with infrequent incidents
  • Scope can be limited to specific components, SQL Server, Active Directory, Azure, without full-environment cover
  • Convertible to an annual managed IT services agreement at any point

Why Organisations Choose Zaco Computers for Microsoft Support

💰

Guaranteed Cost Reduction Without Compromising Coverage

Zaco replaces the percentage‑based pricing of Microsoft Unified Support with a fixed, environment‑specific model. Organisations typically reduce their Microsoft support costs by up to 50%, without reducing coverage or service quality. This approach removes the automatic cost increases tied to Azure growth, Microsoft 365 expansion, or additional Microsoft products. Renewals remain predictable, and support expenditure aligns directly with the systems in use.

Faster Response Times with 24×7×365 Engineering Access

Zaco provides continuous access to experienced Microsoft engineers through a global service desk. There are no tier‑based restrictions or after‑hours limitations. This structure consistently delivers faster response times, quicker escalation handling, and shorter resolution cycles compared to traditional OEM support. Organisations benefit from reduced downtime and more stable Microsoft IT support across their infrastructure.

🏆

Deep Microsoft Expertise Without Hiring or Training Costs

Zaco provides direct access to a skilled engineering team covering Windows Server, SQL Server, Active Directory, ADFS, DNS, DHCP, IIS, Hyper‑V, Azure DevOps, and hybrid cloud environments, eliminating recruitment delays.

🎯

SLAs Matched to Each System's Criticality

A production SQL Server running business-critical workloads carries a materially different response requirement than a development Windows Server instance.

🔄

Freedom From Forced Upgrades and Vendor‑Driven Timelines

Zaco enables teams to continue running stable, customised environments without pressure to migrate immediately. Whether the plan is to maintain current systems, transition to azure managed services, or modernise selectively, Zaco supports the chosen direction without imposing vendor‑driven timelines.

Faster Incident Resolution Across the Microsoft Stack

Independent support models have demonstrated consistently shorter time‑to‑resolution compared to OEM support. Zaco’s engineering structure avoids multi‑layered escalation queues and focuses directly on diagnosing and resolving issues. This contributes to faster response times, reduced operational disruption, and more stable Microsoft managed services across on‑premises, hybrid, and cloud environments.

FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions about Third-Party Microsoft Support Services

1. What is Microsoft third-party support and how does it differ from Unified Support?
- Microsoft third party support means engaging an independent provider for break/fix incident resolution, and technical guidance across your Microsoft infrastructure, rather than purchasing support directly from Microsoft.
The core differences are pricing model and coverage scope. Microsoft Unified Support is priced as a percentage of your total annual Microsoft spend, with a minimum annual contract of $50,000 for the Core tier (price as on 25/02/2026). Our Microsoft support is scoped to your actual environment, pricing reflects the systems you need covered, not your entire Microsoft spend.
2. Which Microsoft components and versions are covered under your managed services?
- Our Microsoft third party support covers Windows Server 2012 through 2025, SQL Server 2008 through 2022, Active Directory, DNS, DHCP, DFS, Azure DevOps, Hyper-V, Dynamics CRM, ADFS, Remote Desktop Services, IIS, and more. Microsoft 365 managed services and Azure-based environments are also within scope. See the full component list in the Microsoft section above.
3. We are running Windows Server 2012 R2, which has passed end-of-life. Can you still support it?
- Yes. Windows server 2012 r2 end of life from Microsoft means the OEM no longer issues security patches or provides direct microsoft it support. However, organisations often need time for a controlled migration. We provide active support, and advisory for these environments while a migration strategy is developed at the organisation's pace.
4. Does your third-party support extend to Microsoft 365 or Azure cloud environments?
- Yes. Our support covers Azure infrastructure environments — including Azure DevOps, Azure-hosted workloads, and hybrid on-premises-to-Azure configurations. For Microsoft 365, we cover configuration, administration, and integration with your on-premises Active Directory and ADFS. We manage the layers your team is responsible for — identity, connectivity, and access — which is where most real-world issues occur.
5. Can you help evaluate whether to stay on current Microsoft versions or plan a migration?
- Yes. Our Technology Advisory service provides this assessment objectively. We review your Windows Server, SQL Server, and connected Microsoft infrastructure and give a clear, documented recommendation based on your operational requirements, security exposure, and cost position, not Microsoft's commercial roadmap or Azure migration incentives. Where migration makes sense, we advise on practical pathways: upgrade in place, transition to azure managed services, or migration to a newer on-premises infrastructure platform.
6. How are SLAs structured for Microsoft managed services agreements?
- SLAs are fully customisable at the individual system level. A production SQL Server hosting mission-critical data carries a different response and resolution target from a test Windows Server instance, a level of granularity that Microsoft Unified Support's fixed performance tiers do not offer. Both annual managed IT services agreements and on-call engagements include SLAs agreed during onboarding. Annual contracts provide predictable cost and highest-priority response. On-call arrangements suit organisations that need expert Microsoft IT support as incidents arise, without a standing commitment.
7. Can you supply Microsoft licences as well as providing support?
- Yes. We supply new and renewal Microsoft product licences alongside our Microsoft support and managed services engagements. We review actual usage and licence position before recommending any purchase and handle procurement directly when a renewal or new licence is genuinely needed, with transparent pricing and no surprise true-up billing.
