    Title says it all, really. I want to have a shortcut on my desktop so I can alter the priority of a process that runs at the normal priority - priority "8" according to Sysinternals's "Process Explorer".

    The process is MsMpEng.exe - MS's Security Essentials.

    The reason why I want to do this is because currently it uses 95+% CPU time while it's doing it's daily scan - no big deal, I can have a cup of tea - but it also pops up at many other times, while I am copying files or doing other things. That is where it bugs me.

    Here are some recent Google results from people with the same CPU usage problem:

    http://www.google.com/search?q=msmpe...k&ved=0CAoQpwU

    I have added everything I can think of to MSE's Settings "Excluded Files and Locations" and "Excluded Processes".

    What I now do, is to lower its priority to 4 using Process Explorer. But that takes many left and right clicks to achieve.

    I have written a command file that kills MsMpEng.exe and msseces.exe, and starts msseces.exe at a low priority. But I can't find a way of starting MsMpEng.exe at a low priority.

    To kill them, I use these commands:

    > taskkill /f /im MsMpEng.exe
    > taskkill /f /im msseces.exe

    To run msseces.exe, I use:

    > c:
    > cd "\Program Files\Microsoft Security Essentials"
    > start /Low msseces.exe

    This will start msseces at priority 4.

    But the equivalent for MsMpEng does not work:

    > start /Low MsMpEng.exe


    In fact, I could not get it to start it all until I noticed an error message calling it a "service".

    So then I found out how to start services, and this worked:

    > net start "Microsoft Antimalware Service"

    These messages were displayed:

    "The Microsoft Antimalware Service service is starting.
    The Microsoft Antimalware Service service was started successfully."

    However, I cannot get it to start at low priority. Sprinkling "/low" in different places on the command line doesn't work.


    So, can anyone offer a solution that allows me to either:

    a. start a service at low priority, or
    b. use a utility to change the priority (once it is running) from a command line.


    Many thanks in advance if you can help.

    Start Task Manager. Right click on the process you wish to manage. Select "Set Priority". Click on the priority you wish.

    Sorry Joe, did you miss the bit about "command line utility"?

    What you suggest is similar to what I do now, but I use Process Explorer to do it.

    If I had a utility that accepts command line input, I could run it at any time - including at startup - and set the priority straight away so I wouldn't have to worry about it.

    So you see, I'm very lazy and want these MSE processes de-prioritised as soon as the computer starts.
