    Cross Device Service High CPU Usage

    Hi, leginmat90. I'm sorry to hear you're having this problem, and I hope I can assist you to find a satisfactory solution.

    I will leave you step by step to disable this service.

    Disable Cross Device Service

    Press Win + R to open the Run dialog box.

    Type services.msc and press Enter.

    In the Services window, locate the Cross Device Service.

    Right-click on it and select Properties.

    Change the Startup type to Disabled.

    Click Apply and then OK

    Hope it helps.

    Cross Device Service High CPU Usage

    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.
