    Since upgrading to Parallels 16, my Windows VM becomes almost unusable during Microsoft Teams meetings with Task Manager at 100% CPU utilization with MS Teams being the culprit. This is only occurring during meetings, if not in a meeting Teams runs as expected.

    I'm using Parallels 15.1.4 Pro Edition and suffer the same problem during Teams calls. I'm interested in anyone who might know why this is. It doesn't happen with Zoom.

    Hello please upgrade to the Parallels Desktop to the latest build 15.1.5 and check the issue.
    Please share any results with us.

    Unfortuantely i do have a similar issue. Teams on Parallels VM causes the fans on MacBookPro to start spinning immediately at 4500revs, which causes a notable noise for other meeting participants. Switching off the camera helps but the fans are spinning still sound 3000 revs, which is completely unacceptable. Teams directly on MacOS does not show this behavior.

    Since upgrading to Parallels 16 (Version 16.1.3), running Microsoft Teams app under Windows 10 VM randomly will cause all Bluetooth devices (keyboard, mouse, headphones, etc.) to stop working and then return. The CPU will be go over 100% during the meeting where Video or Audio is being streamed.

    My MacMini is a 2020 edition, 3GHz 6 core i5 with 64GB RAM and I have 32GB dedicated to the Windows 10 Pro VM. Until the Big Sur upgrade, I rarely if ever had an issue with the VM even with Teams I was fine. Now it's almost useless especially if Teams is running. The keyboard, mouse, audio, video all lag significantly, and the CPU and disk usage is out of control, keeping the CPU pegged at about 100% inside the VM, and the Mac is just just fine.

    The topic was started for a problem with Parallels 16. A newer version than the 15.1.5 you are suggesting to upgrade to. Therefore the original question remains unanswered/unresolved. I have had the same issue on all Parallels versions since the upgrade to 16.
    I just upgraded to version 16.5.0 (49183) and the issue remains.
    Extreme use of CPU during Teams meeting especially while sharing a screen. It drains a full battery in 30mins.
