  • This is not related to to the forum.

    Anyway, windows maintains MRU list that is 'Most Recently Used' items List in registry which is located here

    HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify\PastIconsStream

    If you delete PastIconsStream key, it will clear history.

    Note: Playing with registry _is dangerous.

  • You need to restart explorer to see effect.

    Applications are not supposed to bother about removing it. Further, MRU is a binary data which you need to decode and delete your specific icon entry which is.. uhh.. forget it.. kind of job. If you delete other icons all together, no, you're not supposed to do that.

  • Microsoft says this:

    How do I clear past items from the Customize Notifications dialog box in Windows XP?  

    That Key I gave is for Vista.

    I dont see any difference in method.

  • If it was working on Vista and Now its Not working on Windows 7, first confirm that its indeed a problem and report bug.

    Start | Run | rundll32.exe FeedbackTool.dll, ShowWizard

  • I am moving this thread from Windows Form Sample Applications forum due to this thread is not related to windows forms application developing.

    But I have no idea which is the right forum to ask. So I move this thread to “Where Is the Forum For...?”.

    Thanks for your understanding.
