Microsoft is implementing a solution to address performance issues in Microsoft Teams on Windows, specifically targeting crashes and slowdowns. A new background process, ms-teams_modulehost.exe, will be added to the desktop version of Teams to manage call-related functions separately from the main application. This change aims to reduce system strain, decrease crash rates during meetings, and improve startup times. The strategy builds on the existing architecture of Teams, which uses WebView2, and seeks to offload complex features to enhance performance. Users have reported frequent freezes, delays, and high RAM usage with Teams. While this modular approach is intended to provide immediate improvements, some experts suggest that a complete redesign as a native Windows application would be a more effective long-term solution.
