icloudhome.exe excessive cpu use on Win10

I'm using the new iCloud for Windows 15.0.215 on 64-bit Windows 10 Pro 22H2.


Whenever my laptop sleeps, the fan soon starts running, and the culprit appears to be iCloud.


App History shows it's a MASSIVE CPU hog:


And in Task Manager, no other app comes close:


As soon as you start using the laptop again, the fan quietens down and iCloud appears to be behaving itself.


Windows is fully up to date, and I've tried uninstall/reinstall of iCloud - any other bright ideas?!

Exactely the same issue here. When the PC gets out of sleep (in the graph at 21:39:15) the process goes back to using no CPU.

Hello. I've noticed the same thing and logged the processes so i found the same results as yours. icloudhome.exe starts using lots of cpu only when the screen is off. Reported the app on the microsoft store. We need to report Apple. It's possible that someone is running a miner from inside Apple and making lots of money out of this.

I'm seeing the same issue. Years ago, I would projects like SETI@Home, and this acts like it. As soon as I actively start using the computer, the CPU drops off. I see the same behavior in the App history tab in Task manager as well. I have had issues in the past with having iCloud for Windows when it came to the iCloud Drive feature. I end up turning that one off, but in this case, it looks like I would have to completely uninstall iCloud to avoid this.
