Windows Update Notification icon missing, but updates have been fetched...

    Question

  • XP with SP3, Dell Inspiron 2650, 512Mb, 60+Gb free space on the hard drive after extensive program removal and data deletion; this is a system that was recently acquired, and I don't have a lot of history on it, but it came close to needing a nuke & pave due to the previous owner's habit of never deleting anything.  The sytem apparently fetches Windows updates, but the WU icon in the Notifications area never appears, and there does not seem to be any way to identify which updates are pending without that point of access.  At shutdown, the fact that updates are available is noted, so I know they're present and waiting, but I'd like to review them before installation.  I have tried reinstalling the Windows Update utility itself via the downloadable installer (WindowsUpdateAgent30-x86.exe) but that did not fix the problem.  No other services are noted as being necessary in the Properties for the Windows Update service, so I don't know if a disabled service might be keeping the notification from appearing.  Any suggestions?

  • Cause:
    When the Windows Update icon is missing, this is mostly caused by an already running wuauclt.exe process in the user context of the first logged on user (session ID = 1). The wuauclt.exe process will only be started once on a system. All other logged on users (session IDs = 2 to n) do not see the Windows Update icon in the system tray.

    Resolution:
    Log on via console (type mstsc /admin in the run dialog on the source client with that you log on via RDP to the destination server/destination client). As you are lo
    gged on via console now, your session ID will be = 0. Now open task manager and stop the wuauclt.exe running in the user context of the user logged on to session ID = 1. wuauclt.exe will restart in your user context (session ID = 0) within one minute. The Windows Update icon will appear in the system tray now (if updates are found by the server/client). If not, check the logfile (C:\Windows\SoftwareDistribution\ReportingEvents.log) to see if there are other problems with Windows Update.

    Wenn das Windows Update Icon unter Windows Server 2003 im System Tray fehlt, dann liegt das im Regelfall daran, dass die wuauclt.exe im Userkontext des ersten angemeldeten Users (Session ID = 1) gestartet wird. Die weiteren angemeldeten Nutzer (Session ID = 2 – n) sehen daher das Windows Update Symbol nicht im Tray.

    Eine Möglichkeit ist es dann sich per Console (Session ID = 0) anzumelden und den Prozess wuauclt.exe, der unter dem ersten angemeldeten User läuft, per Taskmanager zu beenden. Der Prozess wuauclt.exe wird automatisch erneut unter dem User mit der niedrigsten Session ID gestartet (das ist dann natürlich derjenige, der per Console angemeldet ist).

  • Initial workaround:  %windir%\Software Distribution contains a log file which details the downloaded updates.  There's still the question of how to disallow one that isn't wanted for some reason, which isn't the case for the moment, hence although the workaround is useful, it's not a real solution.

  • Hi,

    What appears is not only the notification balloon? or icon?

    If the notification balloon see the link below:

    If the icon try the following procedure:

    If not try:

    - stop the WU service

    - enter commands at the DOS prompt

    regsvr32 wuapi.dll
    regsvr32 wuaueng.dll
    regsvr32 wuaueng1.dll
    regsvr32 Wucltui.dll
    regsvr32 wups.dll
    regsvr32 wups2.dll
    regsvr32 wuweb.dll

    - Start the WU service
