Teams has just recently started consuming all of the available CPU on my Windows 11 PC. Total CPU is at 100% with Teams consuming anywhere from 60-98%. This is resulting in a very sluggish user experience making my PC nearly unusable. When I kill the Teams process via Task Manager, CPU utilization drops to <20%. I've been using Teams on this PC for years without any prior issues.

Windows 11 Pro 22H2 (OS build 23481.1000)

Teams Version 1.6.00.12455 (64-bit)

I've performed the recommended troubleshooting steps below:

  1. Checked for Windows & Teams updates
  2. Disabled GPU hardware acceleration
  3. Disabled animations
  4. Disabled read receipts
  5. Disabled "Register Teams as the chat app for Office"
  6. Cleared the Teams cache (%appdata%\Microsoft\teams)
  7. Repaired & Reset Microsoft Teams
  8. Uninstalled/Reinstalled Teams (along with manually deleting all Teams files)
  9. Rebooted the PC

CPU utilization immediately jumps to 100% upon launching Teams, even just sitting at the login screen before signing into my Teams account. As a workaround, I'm using the browser-based version without any issues.Another user recently reported a similar issue:

    Same issue, different year. Surely this should have been fixed by now?!
