    99% CPU usage - COM Surrogate ?


    I think COM Surrogate task is broken.
    I have 99% CPU usage most of the time.

    I have tried sfc & dism.

    I bought a program to fix problems.
    I think that was a waste of money.

    I have no viruses.

    I cleaned out every junk file I could find.

    I shut off various start up programs.

    If I use Diagnostic start up the problem goes away but I can't connect to the internet.

    If I end the task, it restarts itself.

    I have Googled it.
    I tried various solutions with no success.

    The strange thing is, even with 99% usage, my computer runs pretty fast.

    The last time I emailed Microsoft, they never replied.
    Poor customer support.

    If anyone has any ideas, let me know please.

    EDIT- You have 3 green pips now.

    Its more likely a video codec or an antivirus/antispyware messing around with your computer.
