    Diagnostic Policy Service causing large CPU spikes.


    Recently, my laptop has randomly been having large CPU usage spikes that cause lag due to Diagnostic Policy Service. This has happened before, and I fixed it by ending the process, and deleting SRUDB.dat. However, this time that isn't possible. If I try to end the process, I get informed that "ending this will cause the computer to become unstable and shut down". This means that all the online solutions don't work. Does anyone have any recommendations for fixing this issue now that the online ones don't work?

    :)

    Diagnostic Policy Service - high CPU

    HP laptop problem
    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.
