Windows 11 Task Manager running at 60% continuously since Version 20.4.0 (55980) update

Operating system: Mac OS
Hardware: MacBook M3 64GB ram
VM: Windows 11 Version 10.0.22631 Build 22631
Since the last update to Parallels Version 20.4.0 (55980) windows virtual machine shows Task Manager running continuaously at 60%.

 

Further to this now copy paste does not work between Mac OS and Windows 11 VM.

 

Operating System: Mac OS
Hardware: Mac Mini M4 Pro M3 with 24GB RAM
VM: Windows 11, version 23H2, build 22631.5624

The same thing is happening to me. Since the last update to Parallels, version 20.4.0 (55980), the Windows virtual machine shows Task Manager running continuously at 100%, even though nothing is being done.

 

The Mac Mini M4 gets very hot. After an hour, you can't hold your hand on it. I guess it's not a good idea to use it like that.

 

I'm seeing the same issue with Task Manager running continuously. Copy/paste is working fine.

 

It doesn't seem to be because of Parallels update. For me it happened after installed Windows 11 security update . After I uninstalled that update. The cpu consumption on my MacBook returned to normal.

 

Uninstalling latest updates seems to fix it, took me while to find:
Settings > System > Recovery > Advanced startup > Restart Now

Troubleshoot > Advanced Options > Uninstall Updates > Uninstall latest quality update

 

Thanks Tony! I was burning my lap with my MacBook B4 this

 

Same issue here. I will also try and uninstall the latest windows update to see if it removes the problem.

 

Unfortunately it didn't seem to help. Uninstalled latest update, rebooted, and it was still pegging the performance cores. Reinstalled latest update, and it's still status quo. This is curious.

 

Windows just updated itself today, same issue.

Uninstalling the latest quality update fixed it again, I've paused updates.

This is the history for a working system:

 

Definition updates seem to be fine to install:

 

Hmm, it will only let me uninstall KB5056580, which I do, and it seems to uninstall correctly. But it doesn't give me the option to uninstall KB5062552. Whether I uninstall or reinstall KB5056580, the problem remains. Are you able to uninstall KB5062552?

 

I don't know how to uninstall individual windows updates - there's only the "latest quality update" option, and that fails if I try to run it twice.

 

I tested uninstalling KB5062552 (it was listed as desciribed above). Overnight the update installed itself again - me missing to halt further updates
I uninstalled once again and then I found this advice in another (very old, but woken up) thread. Went wild and updated w/o backing up - feasible if you don't have a lot of apps installed and configs made. #99
