Symptoms

Teams shows several ms-teams/msedgewebview2 processes in Task Manager, the PC slows down during calls, fans spin up, or an 8GB laptop starts swapping when Teams is open.

Why it happens

• WebView2-based architecture spawns multiple browser processes
• Many chats, channels and tabs loaded in the background
• Video calls with backgrounds/effects on low-RAM machines
• Corrupted cache causing runaway processes
• Outdated Teams build without the 2026 calling-process split (ms-teams_modulehost.exe)
