    Random window quickly shows and dissappears

    I just got a new PC and did a clean install. Randomly a window appears but disappears right away so i dont even know where it is coming from. It happens fairly often, at least twice per hr or so. Is there someway to find out which processes or files have recently been loaded so i can quickly look as soon as it happens again?

    Hi, you can capture activity using Sysinternals Procmon (free from MS)

    Initially you will get a LOT of activity and a long log.

    If you set the Filter (maybe 20 or more items) to filter out common system processes, the displayed log can be reduced to almost nothing.

    If your window originates from a different process or event, then all you will see (more or less) will be activity related to that.

    This may take a bit of iteration.

    You can also note the time at which the window appears, and use the time stamp in the log as a guide to where to look.

    You could install Autoruns and check to see what programs / tasks / services are being run on startup. Disable those third party items you don't need.

    Yes, you can try a process of elimination of any programs you have installed since your clean install.

    If the window looks like a command prompt window, there are a couple of threads on such windows appearing and disappearing.

    It might be a scheduled task. If it only appears momentarily, looking at the task man isn't likely to help.
    But Procmon captures everything. Just hard to find what you want.

    Basic process of elimination.
    1. Does it happen in Safe Mode?
    2. Does it happen after a clean boot?

    3. If not, proceed from there, and progressively enable thing until it does.

    If it does, then check scheduled tasks.
