TL;DR: WSUS handles Microsoft update distribution on-prem. Configuration Manager (SCCM) uses WSUS for updates but adds broader endpoint management. Intune manages updates and devices through the cloud. WSUS is deprecated but still supported. There is no need to panic-migrate.
Comparing WSUS, Intune, and SCCM gets confusing because they overlap in Windows update management without actually serving the same purpose. WSUS focuses on Microsoft update distribution. Configuration Manager adds broader endpoint management while relying on WSUS for software updates. Intune manages endpoints through Microsoft's cloud services.
This comparison matters now because WSUS is deprecated, more endpoints live outside traditional networks, and Microsoft supports paths where Configuration Manager and Intune coexist. Understanding what each tool actually owns makes the architecture decision clearer.
What is the difference between WSUS, Intune, and SCCM?
WSUS is an on-prem Microsoft update service. Intune is a cloud-based endpoint management platform. Microsoft Configuration Manager, commonly still called SCCM, is a broader management platform focused heavily on Windows environments. Configuration Manager uses WSUS as part of its software update infrastructure.
These aren't three equivalent patch management products you can swap interchangeably. They occupy different layers of endpoint management.
Capability | WSUS | Intune | Configuration Manager |
|---|---|---|---|
Primary purpose | Microsoft update management | Cloud endpoint management | Broad endpoint and systems management |
Management model | On-prem | Cloud | Primarily on-prem with cloud integration |
Windows update management | Yes | Yes | Yes, through its software update infrastructure |
Requires WSUS for update management | It is WSUS | No | Yes, for the Software Update Point |
Application deployment | No general application deployment; updates only | Yes | Yes |
Device configuration and policy | No general endpoint configuration | Yes | Yes |
Compliance management | Update compliance/status reporting only | Yes | Yes |
Inventory | Update and computer status only; no general hardware or software inventory | Yes | Yes |
Internet-based endpoint management | Not cloud-native | Yes | Possible with additional architecture |
macOS management | No | Yes | No; Microsoft recommends Intune for macOS management |
OS deployment and imaging | No | Modern provisioning workflows | Yes |
Infrastructure burden | WSUS server and maintenance | Cloud service | Site infrastructure plus supporting roles |
Current direction | Deprecated but supported | Actively developed | Actively supported, part of the Intune family |
How does WSUS compare with Intune?
WSUS and Intune can both influence how Windows devices receive updates, but they use different management models. WSUS centralizes Microsoft update approval and distribution through on-prem infrastructure. Intune applies cloud-delivered Windows update policies and manages additional workloads like configuration, compliance, applications, and security settings.
Intune is not cloud-hosted WSUS. The assumption that it is trips people up.
Infrastructure: WSUS requires you to maintain WSUS infrastructure, the server, the database, the sync schedules, the cleanup tasks, and disk space. Intune is cloud-managed. Microsoft handles the backend.
Endpoint location: WSUS aligns most naturally with traditional network-based Windows management. Intune is designed for cloud-managed and internet-connected devices. This matters when your workforce is distributed across home offices, coffee shops, and that one person who insists on working from a camper van.
Scope: WSUS focuses on Microsoft updates. Intune is broader endpoint management that includes configuration, compliance, applications, security policies, remote actions, Windows update policies, and Apple device management.
How updates work: Intune update rings control deferrals, restart behavior, deadlines, active hours, and notifications. They use the Windows Update infrastructure directly rather than pulling updates through your WSUS server. Your devices talk to Microsoft, governed by the policies you set.
How does WSUS compare with SCCM?
WSUS and Configuration Manager are not direct substitutes. WSUS provides Microsoft update services. Configuration Manager provides broader endpoint management capabilities, software deployment, inventory, compliance, operating system deployment, and update management. When Configuration Manager manages software updates through a Software Update Point, WSUS remains a required part of the underlying infrastructure.
A key technical distinction is that Configuration Manager does not replace WSUS for Microsoft update management. For software updates, Configuration Manager uses WSUS for metadata synchronization and update-applicability scanning, then adds targeting, deployment, automation, and reporting.
The relationship works like this: At the top-level site, the Software Update Point uses WSUS to synchronize software update metadata from Microsoft Update. Configuration Manager then synchronizes that metadata into its site database. From there, Configuration Manager can:
Organize updates into software update groups
Distribute update content through distribution points
Deploy updates to clients through software update policies, with maintenance windows when configured
Automate deployments with automatic deployment rules
Manage broader software deployment, scripting, and operating system workloads
So when someone asks "Does SCCM use WSUS?" yes. When someone asks "Does SCCM replace WSUS?" no. SCCM wraps WSUS in a larger management framework.
How do Intune and SCCM work together?
Intune and Configuration Manager can manage Windows devices together through Microsoft's co-management model. Organizations can retain Configuration Manager for selected workloads while moving others, like Windows Update policies or compliance, to Intune. This allows teams to adopt cloud management gradually instead of treating Intune deployment as an immediate Configuration Manager replacement.
The useful concept is defining which management authority owns each workload.
Microsoft lists co-management workloads including Windows Update policies, compliance policies, device configuration, endpoint protection, Office apps, and client applications. You can shift these individually, test the results, and move at whatever pace makes sense for your environment.
For organizations with significant Configuration Manager investments, task sequences, application packaging, and compliance baselines built over years, co-management offers a path that does not require abandoning that work overnight.
When should you use WSUS, Intune, or SCCM?
The right choice depends less on which tool has the longest feature list and more on where your endpoints live, which operating systems you manage, what infrastructure you already maintain, and which management workloads your team actually needs.
Environment or requirement | Tool or approach to evaluate |
|---|---|
Existing on-prem Windows environment with straightforward Microsoft update controls | WSUS may continue meeting the immediate requirement |
Cloud-first or highly distributed workforce | Intune |
Existing large Configuration Manager environment with complex Windows management | Configuration Manager |
Organization gradually moving Configuration Manager workloads to the cloud | Configuration Manager plus Intune co-management |
Centralized Microsoft update approvals in disconnected or highly restricted environments | WSUS may remain relevant |
Endpoint policy and compliance across Windows and macOS | Intune |
Deep Windows OS deployment and established task sequence workflows | Configuration Manager |
WSUS remains particularly relevant for air-gapped or disconnected scenarios where internet-dependent workflows don't fit. Not every environment can assume constant cloud connectivity, and assuming otherwise can create different problems.
What does WSUS deprecation change?
WSUS is deprecated, which means Microsoft is no longer developing new WSUS features. Its existing capabilities remain available and supported for production deployments. Organizations can continue using existing WSUS environments while planning how future endpoint and update management requirements fit into their broader strategy.
Deprecation changes the long-term planning question, not necessarily today's operational state.
Teams should evaluate which WSUS workflows they rely on today, what their future endpoint environment looks like, and whether those workloads belong in Intune, Configuration Manager, PDQ, or another platform. The answer is not always "migrate everything immediately." Sometimes it's "keep WSUS running while you build something better."
Where does PDQ fit with WSUS, Intune, and SCCM?
PDQ gives IT teams a cloud-based way to patch, deploy software, automate tasks, inventory devices, and manage Windows and macOS endpoints. It can replace or reduce many common WSUS workflows in internet-connected environments, and it can also complement Intune when teams want faster operational deployment, patching, scripting, inventory, or troubleshooting workflows.
According to PDQ's 2026 State of Sysadmin report, 51% of sysadmins say timely security patch implementation takes up too much time, and that's exactly the kind of operational work PDQ handles. Automate the patching. See what's vulnerable. Fix it without building a 47-step change request.
Intune can own policy and compliance while PDQ handles day-to-day endpoint operations. The two are not mutually exclusive.
For organizations that specifically want self-hosted management for on-network Windows devices, PDQ Deploy & Inventory remains the on-prem option for software deployment, scripting, inventory, and automation.
If you're evaluating what comes after WSUS, replacing WSUS with PDQ walks through the specifics.

WSUS vs. Intune vs. SCCM FAQs
Does SCCM use WSUS?
Yes. Microsoft Configuration Manager requires WSUS when you use the Software Update Point role. WSUS provides the update infrastructure and metadata synchronization. Configuration Manager adds deployment, targeting, automation, reporting, and broader endpoint management capabilities. Configuration Manager builds on top of WSUS.
Does Intune replace WSUS?
Intune can replace many WSUS update-management workflows for cloud-managed Windows devices, but it is not a direct cloud version of WSUS. Intune manages update policies through Microsoft's cloud services and handles broader endpoint management functions like configuration, compliance, applications, and security policies. The architecture is fundamentally different.
Is SCCM the same as WSUS?
No. WSUS primarily manages Microsoft updates. Microsoft Configuration Manager is a broader endpoint management platform that can deploy applications, inventory devices, manage operating systems and compliance, and manage software updates, but its Software Update Point still relies on WSUS. WSUS is one component within Configuration Manager's larger toolbox.
Can you use Intune and SCCM together?
Yes. Microsoft supports co-management, which allows eligible Windows devices to be managed by both Configuration Manager and Intune simultaneously. Administrators decide which platform manages individual workloads and can move workloads to Intune gradually. This is Microsoft's supported path for organizations that are not ready for a full migration.
Is WSUS still supported?
Yes. WSUS is deprecated but remains supported for production deployments. Microsoft is no longer adding new features, but existing functionality continues to work and receive support. You do not need to rip out WSUS servers tomorrow. But you should be planning for what comes next.
