    Question

  • Windows update is failing attempting to install the Windows Update Agent 7.4.7000.81  The error screen that appears says Windows could not search for new updates and the above error code.

    I have looked high and low through the threads and have found no other occurrance of this error.  I have tried all the fixes for other errors related to Windows Update with no success and now am appealing to the group for assistance.

  • Hi Mark:

    I disabled the antivirus program as well as the firewall and still get the same error.

    Unfortunately, the current file available for download is from October for Vista and will not work.  Would someone have the updated agent 7.4.7000.81 for Windows 7?

  • Fortunately, that is a system file in Win7. I should have told you to run SFC in the first place.

  • so I know this thread is 2 years old almost, but I tried to use it because I use Windows 7 and get the error code 800F081F when I try to use Windows Update. I tried running Microsoft Fixit and it found no problems, and the site nor the Help and Support recognized the error code. The strange thing is that I was able to install updates managed by my system administrator, even though it could not install the windows update installer for updates found online... I tried the above attempts, and they failed... any ideas?

     

    Thanks,

    Andrew

  • Not sure if this is related but I thought I would throw it out there just in case.  I had several Windows 7 computers that could not do windows updates and it was because they all had the same client machine ID (CMID).  I had to rearm and reactivate each machine and now the Windows updates work.
