    Service Host: Disk Defragmenter taking up huge amounts of CPU 24/7

    Seriously, it's starting to concern me how it's permanently taking up this much of my CPU...

    Here's a link showing how much of the CPU it's taking up, it's been like this for days now.

    Hi guys welcome to the forum.

    If you aren't concerned too much about having your disks defragged or you have SSDs you can easily disable the service.

    In the search box on the taskbar, type defrag and open the program that comes up.
    Once the program is running you can disable the scheduled service and that should disable the resident service as well (if it hasn't, post back here).

    Additionally, you can disable it like this. Run CMD as admin and copy/paste:

    schtasks /Change /TN "Microsoft\Windows\Defrag\ScheduledDefrag" /Disable
    reg add "HKLM\Software\Microsoft\Dfrg\BootOptimizeFunction" /v "Enable" /t REG_SZ /d "n" /f
    reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\OptimalLayout" /v "EnableAutoLayout" /t REG_DWORD /d "0" /f
