Teamviewer Release Notes

Operating system - Windows

Version - 15.81.5

Release date - 2026-08-25

New features

• A new driver for Security Key Redirection has been added. The updated driver introduces several technical enhancements, including a fixed-size pool of reusable device interfaces and improvements to Plug and Play (PnP) power management event handling.
• A dedicated section for user management permissions has been introduced, clearly separating user, user group, and user role permissions while highlighting their administrative significance. Additional information icons provide explanations to help users better understand these permissions.
• A new Default QuickSupport Module setting is now available in TeamViewer Remote under Admin Settings → Connection Settings. This ensures a consistent experience by automatically applying company-defined module customizations to sessions.
• Tia Troubleshooting has been enhanced from contextual guidance to AI-driven troubleshooting. Tia can now perform live diagnostics and execute approved remediation actions during remote support sessions on managed Windows devices, helping identify root causes and resolve issues more efficiently.
• Tia now includes three modes: Advise, Diagnose, and Resolve. These modes provide increasing levels of troubleshooting capability, giving users control over how Tia investigates issues and helps resolve them.
• Introduced Tia Toolbelt to bring together tools and data sources such as Session Insights, device context, screenshots, diagnostic scripts, AI-generated diagnostics, and remediation scripts that can be used to solve issues with Tia in a remote control connection.
• Detailed audit traces for Tia-driven troubleshooting have been added to Session Insights. Users can now review actions performed by Tia, including executed actions and who started the execution, providing greater transparency into troubleshooting activities.
• Administrators can now assign Tia Advise, Diagnose, and Resolve access to users and groups through dedicated Tia packages. Device policies can also be configured to control on which devices Tia capabilities are available.

Improvements

• The Active Connections feature is now available in TeamViewer Tensor and TeamViewer One. When enabled by a company administrator, users with the Active Connections permission can view all connections initiated by or to users within their company.
• It is now possible to assign a default QuickSupport module to individual users and legacy groups. This ensures that the predefined module is automatically applied to the selected user or group.
• The way the client receives updates about changes to devices and device groups has been improved.

Bugfixes

• Fixed a bug that could prevent session invitations from working correctly when both the inviter and the invitee were configured for Easy Access.

• Fixed a bug that prevented the assignment pop-up from appearing when managing a device through the custom full client module.
• Fixed a bug that caused the User Management page to appear empty after a company was created.

Response to user question:

Hi @RaphaelV,
Thank you for your post.
Version 15.80.6 is currently available only for the TeamViewer QuickSupport and TeamViewer Host modules, as noted in the Bugfixes section of the changelog. It is not being rolled out to the full TeamViewer client, which is why you're not seeing the update.
To make this clearer, we've updated the changelog accordingly.
If anything remains unclear or if you have any questions, feel free to let us know. We're happy to help!
Best,
Jen
