    Explorer.exe taking up 15-30% CPU usage when moving mou


    I don't have any programs opened just the task manager. When I'm not moving the mouse my CPU usage stay from 0-2% but as soon as I move the mouse pointer, even though just a bit, it shoots up to 30%!!!!

    Why is that happening? I'm really frustrated about it.

    Thanks.

    In order to help you we need you to fill in your system specs (lower left corner) so we know what hardware you have.

    thanks

    What version of windows 7 are you running?

    Did you obtain it legitly?
    If not do the MD5 sums match up?

    If its hacked im assuming your using an activation hack. Which could be causing it.

    RTM 7500 x64.. I got it from torrent but yes the MD5 sums match up perfectly with the original one.

    I'm not using an activation hack. Still on trial mode.

    What program can I use (and how do I use it) to monitor the thread activities of the explorer.exe process?

    Is this the only way to determine which thread is causing explorer.exe to be using high cpu usage?

    I just noticed that even though I totally don't move the mouse pointer, after 30 seconds or so, the CPU usage just boosts up high and after 1 second it drops to 0-1% again.

    BUT, continually moving the mouse pointer will maintain the high CPU usage 20-30%.

    The best tools for this type of investigation are those in the sysinternals suite

    Windows Sysinternals: Documentation, downloads and additional resources

    In particular for this case I would look at

    Autoruns - what automatically starts

    Process Explorer - Enhanced task manager with more in depth information

    Process Monitor - list process use over time for particular process or processes

    Full details and instructions are available on the site

    Looking at your specs - are you using the Logitec drivers for the mouse? - if so you may want to disable these (uninstall) and try running with just the default Microsoft drivers.
    It may be an incompatibility between the current drivers and windows 7.

    I have seen this with other Logitec product drivers during the Windows 7 Development.
