Windows Vista error code 80070490



     I'm having problems with Windows Vista on my laptop. Whenever I try to do a 'Windows Update' for Windows Vista (KB938371, it ended up telling me that "Some updates were not installed. Failed: 1 update. Error code 80070490." Anyone has a solution yet or can help me in anyway?  Thanks!   s law

    I have the exact same problem on my Vaio laptop. I was downloading windows vista service pack one at the same time as downloading a game when the computer crashed and I got the blue scren ofdeath. The computer fixed itself without restoring but now vista service pack one is in update manager and whenever I try to download it and install it it come up with that code.

  • I can't believe there is still NO solution for this! I do NOT want to reinstall Vista, I shouldn't have to. I have not been able to update vista since DECEMBER. I can't not upgrade to SP 1. I can't do a damn thing.

    What is up here! I know.... I am NOT the only one who is having this issue!

  • I am having exactly the same trouble on a Dell XPS480 desktop.


    I tried to apply the Cumulative Update for Media Center for Windows Vista (KB950126) and was awarded with "Failed: 1 update  Code 80070490".


    This happens with each Media Center Update:

    I too am having failures with KB950126.  Checking the update log, it looks as though there is an issue downloading this:


    {4EAB4866-447F-4F74-AB16-E6B18B4C8122} 2008-06-13 12:25:35:175-0400 1 161 106 {2A625336-9B85-4D9D-BF63-DD9123820A78} 104 80070490 AutomaticUpdates Failure Content Download Error: Download failed.


    Each time I attempt to download a Vista update it fails to download, that may be your situation as well.


    You can check your log at c:\windows\softwaredistribution\ReportingEvents.log


    Other updates, such as Ultimate Extras, work fine in my case. Since the error log is not extremely verbose about how it fails I am stuck.


    If you find a solution please post it.

  • Try running "CHKDSK" from the command line, this worked for me. Don't forget you can only run it under administrator privileges, so right click and select "Run as administrator."

    I know this is an old thread, but I came across this error today.  I'm not sure if this will fix the problem for you, BUT it did fix it for me.

    1. Running Avira Antivir (PE), my favorite antivirus software.  Windows Update failed with same error as posted.
    2. Disabled "Active Guard", that is Antivir's real time monitoring. For those with other AV software, try disabling it temporarily.
    3. Ran Windows Update again, and it worked, without any error.

    This may help many of you.

  • Found this posted in Microsoft Knowledge Base. 

    Microsoft Knowledge Base Solution 1:
    This one did not fix it for me, but very well may for you.

    Microsoft Knowledge Base Solution 2:
    1. This update takes time to install.
    2. This did not work for me after installing and trying the other Update.
    3. Will reboot and try again to see if that does the trick, and post results.

    Nothing did the trick for me.  I ended up removing the device (Printer) from Device Manager.  Then ran Windows Update again without the Questionable Device that was requesting some driver  updates.  Then I downloaded the latest Vista versions of the software for my printer and ran the software in Vista compatible mode.  Seemed to do the trick, for now.
