Error code 80070490 searching Windows updates

original title: Code error 80070490

Hi all

I have this Windows Update icon in my tray on the right saying I need to update my computer, which is good, but every time I have try I get

"Windows could not search for new updates"

"Error Found."

"Code 80070490 - updated window has met an unknown error"

So I do not use Windows Live One Care, I use AVG Virus Protection, and it is up to date!

Help, please!

Hi ONTLLs,

The error you receive occurs if there is corruption in the manifest of component maintenance base.  The only way to fix this is to do a "repair" of Windows Vista installation.

http://support.Microsoft.com/kb/958044/en-us
The 'repair' installation (upgrade on-site) will not affect your installed programs or data.  Just make sure that you are already connected to your computer when you start the installation.  Do not boot from the DVD.

If the installation does not start automatically when you insert the DVD, run setup.exe from your DVD player.

  • When the Setup program starts and the install now screen, click install now.
  • Note When you receive the important Get updates for installation message, click go online.
  • Click upgrade when the which type of installation you want? appears

Please let us know if this solves the problem for you.

    Try to run the system update (or CheckSUR) tool to see if it can resolve the error.
    If it cannot, you can edit the CheckSUR.log located atCheckSUR.log Windows\Logs\CBS\
    and maybe we can see what content is not present in the operating system.

    Your operating system is corrupted. To eliminate the problems on your computer, you need to restore factory settings and rebuild your computer system.

    A recovery of the system partition contains a copy of the operating system as it was when the computer was purchased new. Using the copy of Vista, you can restore the computer to factory settings. Of course you must back up your data files to an external before restoring support as the process reformats the disk thus clearing all existing files before writing new files.

    Please read Chapter 13 (page 33) Manual:
    5738 http://global-download.Acer.com/GDFiles/document/generic%20UG/generic%20UG_Acer_1.0_A_A.zip?acerid=633967123940952836&STEP1=notebook&Step2=aspire&step3=aspire & OS = ALL & LC = en & BC = ACER & SC = EMEA_27

    The manual suggests that you have an option to restore the operating system and retain user data that I've not seen in a manual before. It is worth trying because it reduces the work involved but I would again as a precaution, back up your data files on external safety precaution if things go wrong.

  • Error Code 8007000D install Windows updates

    I'm running Windows 7 on a Lenovo X200S.  Windows Update worked until about a month or two ago and has since been giving me "unknown error code' 8007000D.  I ran the Mr. Fixit tool in aggressive mode and it did not help.  I downloaded and installed KB947821 (sytems update tool) manually and it still does not work.  Suggestions how to fix this would be appreciated.  Thank you.

    8007000D - Error_invalid_data.  Corruption in the folder C:\Windows\SoftwareDistribution.  Please rename
    %windir%/SoftwareDistribution folder.

    This is how you do it in Vista so I guess it's the same thing in Windows 7 (check that you restart however that the folder cannot be recreated properly without a reboot).

    How to rename the software D folder in Vista - distribution agent version

    1. stop the Windows Update service (make sure that you are logged on as administrator)

    Start button | Control Panel | System and Maintenance | Administration tools
    Double-click on Services
    (Provide the administrator password or a confirmation if prompted to do so.)
    Right-click the Windows Update service and click on stop.

    2. Click Start, type %windir%\System32 in the search box and press ENTER.

    Find and rename the folder C:\Windows\SoftwareDistribution.

    3. start the Windows Update service

    Start button | Control Panel | System and Maintenance | Administration tools
    Double-click on Services
    (Provide the administrator password or a confirmation if prompted to do so.)
    Right-click the Windows Update service and click Start.

    This procedure will erase your history on the Windows Update Site. Not important.
    You can always check what updates have been installed quite easily.
