    I've tried some of the solutions on reddit about running that Bat script or deleting the folder in System32 that causes it but none seem to solve the problem.

    Virus scans come empty handed as well. Restarting doesn't help. I can't game and if I use the computer for more than 4 hours can't even watch YouTube without freezes.

    Diagnostic Policy Service - high CPU

    In the last few days, this laptop started having poor performance, with Task manager showing Diagnostic Policy Service taking up to 30% or more of CPU.

    Did upgrade of BIOS, no improvement.
    Downloaded all current windows upgrades – no fix.
    I created a new (admin) user, same problem.
    I ran all of the diagnostics in the HP Support Assistant, all passed – no effect.
    I ran "sfc /scannow." and "Dism /Online /Cleanup-Image /RestoreHealth" – no effect.

    There is an online thread on this in the HP forums, which does not seem to show any fix.

    The HP support is abysmal – it took several minutes for him to echo back “so this is your computer system?”, and then the only suggestion was a factory reset.

    Diagnostic Policy Service keeps taking 20% or more of CPU Usage

    Consistent CPU Usage by Service Host : Diagnostic Policy Service


    Hello Guys,

    I'm using Windows 10 Home Single Language 64-bit. After the latest Windows update in Feb 2018, I've been experiencing consistent CPU Usage (13-14%) by a Windows Process (Service Host: Diagnostic Policy Service).

    I can't figure out why is this process taking CPU usage every time even when the system is idle. *Huh

    I tried to limit its startup, by changing its startup type to Manual, but this went in vain.

    A screenshot has been added to make it more clear.

    Any tips or tweaks regarding this?

    Thanks
