Keeping Microsoft Teams Rooms updated is essential for performance, security, and reliability. This guide covers the full MTR‑W and MTR‑A update process, including update rings, firmware updates, admin controls, and lifecycle behavior — all with verified Microsoft references.
1. Teams Rooms on Windows (MTR‑W) Update Process
Microsoft Teams Rooms on Windows update automatically every night using a built‑in update task. This process checks Windows Update and the Microsoft Store for Teams Rooms app updates. [1](https://blog.chiffers.com/managing-a-microsoft-teams-room-mtr-device-with-intune-part-2-updates/)
Automatic Update Cycle (Nightly at 2:01 AM)
- Checks for Windows OS patches
- Installs Microsoft Store app updates
- Reboots and returns to Teams Rooms interface
Update Rings via Teams Rooms Pro Management
Organizations with Teams Rooms Pro can control the rollout via configurable update rings. [2](https://www.hubsite365.com/en-ww/crm-pages/create-update-rings-for-microsoft-teams-rooms-mo-mondays-ep-15.htm)
MTR‑W Update Rings Table
| Ring | Description |
|---|---|
| Validation Ring | Updates tested on a small set of devices to confirm stability. |
| General Ring | Main rollout for most meeting rooms. |
| Final Ring | Final deployment after validation success. |
Requirements for Windows Update Management
Microsoft requires:
- OEM-provided base system image
- Correct Windows IoT/Enterprise edition
- Windows Update not blocked by WSUS or firewall
Manual Update Option (Offline Update Script)
Admins can manually push app updates using the official offline update PowerShell script if Microsoft Store updates fail. [4](https://learn.microsoft.com/en-us/microsoftteams/rooms/manual-update)
2. Teams Rooms on Android (MTR‑A) Update Process
Firmware and Teams app updates for Android-based Teams Rooms devices are managed through the Teams Admin Center (TAC). Microsoft recommends auto‑updates to comply with Modern Lifecycle policies. [5](https://learn.microsoft.com/en-us/microsoftteams/devices/android-version-support)
Android Update Ring Phases
Microsoft delivers firmware in a structured 60‑day phased deployment cycle. [6](https://techcommunity.microsoft.com/blog/microsoftteamssupport/moving-teams-android-devices-to-aosp-device-management/4140893)
| Phase | Days | Description |
|---|---|---|
| Validation | 0–15 days | Updates applied only to validation‑assigned devices. |
| General | 16–45 days | Default ring; most devices receive updates here. |
| Final | 45–60 days | Last group to receive updates after full validation. |
Year‑End Auto‑Update Freeze
Between Dec 20 – Jan 12 each year, Microsoft pauses all automatic Teams Android updates for stability protection. Manual updates still work. [7](https://m365admin.handsontek.net/teams-admin-center-auto%e2%80%91updates-teams-android-device-firmware-apps-will-paused-year%e2%80%91end-holidays/)
AOSP Device Management Migration
Teams Android devices now rely on AOSP Device Management, which governs firmware delivery and ensures consistent update behavior. [6](https://techcommunity.microsoft.com/blog/microsoftteamssupport/moving-teams-android-devices-to-aosp-device-management/4140893)
