The way Microsoft Intune delivers updates to managed devices has significantly improved. With priority‑based processing and enhanced notification systems, 90% of policy updates, app deployments, and device actions now complete in under one hour.
This article explains the architecture behind faster update delivery and provides practical guidance for IT admins.
What’s new in update delivery?
Microsoft has introduced several improvements to accelerate update delivery:
| Feature | Benefit |
|---|---|
| Priority‑based processing | High‑impact actions (security policies, remediations) are handled faster than routine tasks |
| Enhanced Windows notifications | Uses both Windows Notification Service (WNS) and the Microsoft Teams protocol via the Intune Management Extension |
| Optimized iOS check‑ins | Adjusts scheduling during peak times to prioritize urgent updates |
| Multi‑update coordination | Better management of simultaneous updates to maintain consistency |
These improvements help organizations maintain security and productivity by delivering critical changes without unnecessary delays.
How Intune delivers updates to devices
Intune is designed for distributed environments where devices aren’t always connected to the internet. It uses an eventual consistency model – devices gradually receive and apply updates without interrupting users.
[!NOTE]
The common assumption that updates can take up to 8 hours to apply is a misconception. That timing relates only to routine maintenance check‑ins. In practice, Intune uses a more efficient, notification‑driven system.
Types of device check‑ins
| Check‑in type | Description |
|---|---|
| Single device check‑ins | Triggered when a user or admin performs an action (e.g., installing an app) |
| Change‑based check‑ins | Triggered through push notifications to deliver urgent updates quickly |
Fast Lane notification architecture
The earlier system had significant limitations:
- Only one fast notification was sent per device every 30 minutes.
- Additional requests weren’t queued or retried.
- Missed updates were postponed until the next device check‑in.
Observations showed that 30% of notifications within a 30‑minute window targeted the same devices, and 90% of multiple changes occurred within 15 minutes.
The Fast Lane architecture addresses these limitations by:
- Placing device actions and server changes into priority queues.
- Routing notifications through WNS, APNS (Apple Push Notification Service), and FCM (Firebase Cloud Messaging).
- Supporting enhanced reliability, delivery receipts, and better visibility of online presence.
Enhanced Windows notification delivery
Intune now improves Windows device notification delivery by complementing WNS with the same protocol used by Microsoft Teams. This enhancement:
- Reduces delays caused by offline devices, poor network connectivity, or low battery conditions.
- Provides better traceability for troubleshooting notification and check‑in issues.
- Ensures policies, apps, and security updates are applied without unnecessary delays.
Delivery Optimization for faster updates
Delivery Optimization helps reduce bandwidth consumption and speed up updates:
- Peer‑to‑peer sharing – Devices share update content across the local network.
- Reduced redundant downloads – Fewer devices download the same content from the internet.
- Cost savings – Especially valuable in limited‑bandwidth environments.
Expedite policies for urgent security updates
For critical security situations, Intune offers expedite policies that accelerate specific Windows security updates. These policies:
- Bypass deferral settings and normal deployment timing.
- Don’t require pausing existing monthly update policies.
- Install the specified update as quickly as possible.
[!IMPORTANT]
Not all updates are eligible for expediting. Only supported Windows security updates can be expedited. For regular monthly quality updates, continue using standard update mechanisms.
Prerequisites for expedited updates
Before using expedite policies, ensure your environment meets these requirements:
| Requirement | Details |
|---|---|
| Windows editions | Pro, Pro Education, Enterprise, or Education (Windows Enterprise LTSC is not supported) |
| Device management | Devices must be managed by Intune, Microsoft Entra joined, or Microsoft Entra hybrid joined |
| Telemetry | Must be turned on (minimum setting: Required) |
| Licensing | Microsoft Intune Plan 1 and a Windows license with Autopatch entitlement |
Create an expedite policy
- Sign in to the Microsoft Intune admin center.
- Select Devices > Windows updates > Quality updates.
- Select Create > Expedite policy.
- Choose the specific KB update to expedite.
- Set installation deadlines and restart grace periods.
- Assign the policy to target device groups.
[!NOTE]
For Windows versions earlier than 24H2, devices require the Update Health Tools (KB4023057).
Summary of key improvements
| Component | Previous behavior | Current behavior |
|---|---|---|
| Notification frequency | One every 30 minutes | Priority‑based, batched delivery |
| Update completion time | Up to 8 hours (typical) | 90% in under 1 hour |
| Windows notifications | WNS only | WNS + Teams protocol |
| Multiple changes | Could cause delays | Coordinated handling |
| iOS check‑in | Fixed schedule | Optimized during peak times |
