Microsoft Teams Rooms (MTR) – Request for Official Windows 11 25H2 Support and Upgrade Guidance

Hi Robert,

Thank you for raising this lifecycle planning question. 

Based on current official Microsoft documentation, Windows 11 24H2 is the supported and recommended OS for Microsoft Teams Rooms (MTR) on Windows, with a minimum Teams Rooms app version of 5.3.205.0. At this time, Windows 11 25H2 is not yet listed as a supported version in the Teams Rooms lifecycle documentation, so Microsoft has not provided an official support statement for it. 

Microsoft’s guidance also highlights that new Windows feature updates are not immediately made available to Teams Rooms devices. Instead, there is typically a validation period of up to six months or more after general availability. During this time, Microsoft verifies compatibility across the Teams Rooms app, certified hardware, and peripherals. As a result, customers should not manually upgrade devices to newer Windows versions (such as 25H2) using policy overrides or third-party tools, as this can lead to instability or unsupported configurations. 

For reference: Teams Rooms app and Windows versioning support - overview 

For the current supported path, organizations should: 

• Keep devices on Windows 11 24H2 
• Ensure the Teams Rooms app is updated (version 5.3.205.0 or later, preferably the latest release) 

For reference: Release notes for Microsoft Teams Rooms - Microsoft Teams 

Regarding lifecycle timelines, Teams Rooms devices run on Windows 11 Enterprise or Windows IoT Enterprise (General Availability Channel). These editions have a longer support lifecycle, with: 

• Windows 11 24H2 supported through October 12, 2027 
• Windows 11 25H2 expected through October 10, 2028 

(Note: the October 2026 date applies to Home/Pro editions, which are not supported for Teams Rooms.) 

For hardware requirements, Microsoft recommends using certified Teams Rooms devices that meet Windows 11 requirements. Some older devices cannot upgrade to Windows 11 and must be replaced. Customers should verify compatibility with OEM guidance and use tools like Teams Rooms Pro Management or Windows readiness checks. 

Therefore, the recommended planning position is: 

• Do not move to Windows 11 25H2 until Microsoft explicitly lists it as supported 
• Stay on Windows 11 24H2 + latest Teams Rooms app 
• Monitor Teams Rooms release notes and lifecycle documentation for future support announcements 
• Validate hardware readiness before any upgrade planning 

In summary: Microsoft has officially confirmed support for Windows 11 24H2 on Teams Rooms, but there is currently no published support statement for Windows 11 25H2. The recommended upgrade path is to remain on supported configurations and adopt new Windows versions only after they are formally validated and documented for Teams Rooms. 

I hope this information helps clarify your options. If you have any further questions or need assistance, please don’t hesitate to reach out.
