Microsoft Teams Rooms app version support

  • Article
  • Applies to:
    Microsoft Teams

The Microsoft Teams Rooms app gets updates through the Windows store. The app uses an evergreen product lifecycle and only the current and the next most recent version of the app are supported at any given time. The app bundles a specific version of the Teams desktop app that is modified for room use. The Teams desktop app updates every two weeks while the Teams Rooms app updates less frequently. This means Teams Rooms app current-1 version can be up to six Teams desktop app updates behind, so it's recommended to keep the Teams Rooms app updated to the latest version at all times. Learn more about the Teams update process.

The support structure for Teams Rooms is dynamic and depends on the availability of the latest version. When you encounter a code defect in a version of the application that's not the latest, you must install the latest version to receive a fix.

All releases are listed in the Microsoft Teams Rooms release notes.

Important

When installing a new device that came with an older version of the Teams Rooms application, it is recommended to manually update the application after setting the account, before downloading any Windows updates. This ensures correct OS version and Windows updates are installed on your device.

Windows release support

Microsoft Teams Rooms requires the Windows IoT Enterprise or Windows Enterprise SKUs under the Global Availability Channel servicing option. These other Windows editions aren't supported:

  • Windows Enterprise Long-term Servicing Branch (LTSB) / Long Term Servicing Channel (LTSC) editions
  • Windows Internet of Things (IoT) Enterprise LTSB / LTSC editions
  • any other edition of Windows such as Windows Pro or Home edition

New Windows feature updates aren't offered on Microsoft Teams Rooms devices immediately. There's an intentional delay of up to six months or more after the general availability date published on the Windows release information page. This time is used to validate Windows release compatibility for the Microsoft Teams Rooms app, device hardware, and certified audio video peripherals. Validation begins and continues during active development of each major release of Windows. Extra time is needed to validate that all device manufacturers have built updated images for their devices, and for Microsoft to certify and test those images. During the validation period, the Microsoft Teams Rooms app uses Windows Update for Business group policies to delay Windows feature updates. After any compatibility issues are found and resolved, the block is lifted via updating group policies through a new app release in Windows store. Devices that run the Microsoft Teams Rooms app automatically update to an appropriate Windows release during the nightly maintenance reboot. An MSI version is made available for customers that need to manually manage updates.

Important

During the validation period, Microsoft Teams Rooms devices should not be updated to the next release of Windows by any means. This includes overriding the group policies in place, or using System Center or other third-party device management services. Any of these may cause issues for the Microsoft Teams Rooms app or may leave devices unusable.

The following table shows recommended and supported versions of Windows that are verified to support Microsoft Teams Rooms. All dates are listed in ISO 8601 format: YYYY-MM-DD.

➀ In order to maximize service life, hardware that is not Windows 11 eligible will upgrade from Windows 10 21H2 to Windows 10 22H2. However, take note of the Windows 10 IoT Enterprise end of support date.

➁ Windows 10 version 2004 is not recommended due to compatibility issues found with the Microsoft Teams Rooms application. This specific issue causes the Microsoft Teams Rooms application to fail to start after the nightly reboot.

➂ Windows 10 version 1809 is not recommended due to compatibility issues found with the Microsoft Teams Rooms application. This specific issue causes the Microsoft Teams Rooms application to fail to start after the nightly reboot. This issue was addressed in Windows 10 version 1903.

When you use a supported version of Windows 10, you will always get the latest application updates for the Microsoft Teams Rooms app.

Delay upgrade to Windows 11 on eligible devices

If you need to, you can delay the upgrade of your Teams Rooms device to Windows 11 22H2 until November 20, 2023.

To delay the upgrade, you need to set the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PPI\SkypeSettings\CBU11 value to 1 (DWORD). We recommend setting the CBU11 value using group policy, Intune, or remote PowerShell. Alternately, you can complete the steps below on each Teams Rooms device.

Important

If you want to temporarily delay the Windows 11 upgrade on eligible devices, you need to set the CBU11 value before June 20, 2023.

  1. Switch to admin mode on your Teams Rooms device.
  2. In admin mode, open Registry Editor.
  3. Go to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PPI\SkypeSettings registry key. If it doesn't exist, create it.
  4. Create the value CBU11 and set it to 1 (DWORD).

Once the CBU11 value is set, the device won't be upgraded to Windows 11 until November 20, 2023. If you're ready before November 20, 2023, delete the registry key to resume the upgrade.
