Windows Security Updates Fail

Posted on 2007-10-16
Last Modified: 2008-01-09
I have an issue with Windows Updates not installing. The machine came to me with an illegal XP Pro license installed. It had an old IDE Hard Disk that was playing up. I installed a new SATA disk and mirrored the two using Ghost2K3. My plan was to run the KeyUpdateTool.exe to give the machine a legitimate key and storm ahead. The machine has the latest BIOS available for the board, new memory and new SATA drive.
OS is Windows XP Pro SP2 build 2600, AMD Athlon Processor with a Foxconn/VIA KT Technologies K600-8237 mainboard. The machine itself runs flawlessly but it won't install an update.  Any advice would be appreciated.

    What error do you get if you try to install an update?

    Here is my list of things to try in such cases. Some of these may not apply here, but others may help:

    (a) Check both the date and time on your system. If they are off by more than a few minutes, updates will sometimes fail to install.
    (b) Examine the file C:\WINDOWS\SoftwareDistribution\ReportingEvents.log (with Notepad) to see if there is an explanation of why the update failed.
    (c) Make sure you are logged in with Administrator privileges. Most security updates require it.
    (d) Download the update separately from the corresponding KB article page at Microsoft, and try installing it manually.
    (e) Open a command window and register the following DLL's (this is particularly effective if you recently upgraded your OS)
          regsvr32 wuapi.dll
          regsvr32 wuaueng1.dll
          regsvr32 wuaueng.dll
          regsvr32 wucltui.dll
          regsvr32 wups2.dll
          regsvr32 wups.dll
          regsvr32 wuweb.dll
    (f) Work through the troubleshooting tips at

    (h) There could be corrupted updates in the download folder. Try the following:
         Open a command prompt window and type "net stop wuauserv" (without quotes)
         Rename the downloads folder, e.g.
         "rename c:\windows\softwaredistribution c:\windows\badupdates"
         Restart the update service, type "net start wuauserv"
         Start IE and try the updates again.
    (i) Make sure you are using a recent version of Internet Explorer (v6.0 or later).

    Make sure the Automatic Updates service is running.
    Make sure the BITS (Background Intelligent Transfer Service) is running.
    Make sure the Event Log service is running.

    Also, ensure you have added windows update (and all sub-sites) to the trusted sites list.

    If you have any more questions, let me know.

    Thanks Guys, I had a chat to a Kabbilan Ratha at Microsoft. He was most helpful. He emailed me a couple of batch files that I ran in safe mode and everything is as it should be.

    Thanks for your input and comments.
