Cross Device Service High CPU Usage

Hi I can't locate device cross service in service window.

the same.

On my machine, terminating the process would release the CPU usage returning things to what I would consider normal, however upon restarting the machine the issue would return and the service would be running again consuming 15-20% CPU.

In the end, what fixed it for me was...

1. To disable Across Device Sharing in Settings > Apps > Advanced App Settings > Share Across Devices, select "Off".

2. To disable the "Mobile Devices" start-up app in Task Manager > Startup apps, right-click "Mobile Devices" and select "Disable".

After that, upon restarting/booting the machine, I would no longer have the Microsoft Cross Device Service running in the background and my CPU would be around 5% idle.

Noticed this began a few days ago. Initially, it was my CPU fan running unusually high and also noted high idle temps. The task manager then shows cross device service running my CPU at 7-10% continuously. As soon as I terminate this program, my CPU returns back to normal idle conditions.

How do I disable this feature?

I also noticed this issue in the last couple days. My CPU is constantly running near 20% because of this background service. I can only GUESS that it started doing it after I made an adjustment to the wireless card and rebooted. I went to the advanced properties on the network card and enabled Throughput Booster. Just like the person above, I noticed my fan running high for much longer than usual when the pc wasn't under any load. After opening device manager, I also discovered this was the culprit. At first, I solved the issue by placing it to Efficiency Mode, but after today's update and reboot, it went back to normal and changing that power mode did nothing to fix the issue. That's what led me here. I hate to disable features that actually serve a purpose, but in this case I will. Microsoft needs to find it's own solution to the problem so it will run like it always did... IN THE BACKGROUND! I have switched everything off before I started this write-up, and it's still running at full steam. Hopefully I can just disable the service in Task Manager and the result of switching features off will keep it that way after a reboot. If not, I'll be revisiting that Task Manager after every reboot to disable it until there is a permanent fix in a further Windows update. Good luck to you all!

PS. I never switched the network card feature back to "disabled" to see if it was the cause, but I shouldn't have to because the features aren't even related in function.
