Why does Windows not update?

Posted on 2011-04-29
Last Modified: 2012-05-11
When I shut down my computer it tries to install updates then completes the shutdown process.     When I boot it up again it tries to complete the installation but then says it was unable to do so and proceeds to the logon screen.   I can use it normally, but when I shut it down again it goes through the same process.

    please check the application log in event viewer for any updates that are failing. It could be a corrupt package, insufficient disk or permission issues among other possible causes.

    Once you post the log it can be determined what is failing.

    If you would like to try a few other things before posting the logs:

    Check for sufficient disk
    Run the Update Readiness Tool for your OS [] - It may determine immediately if a certain update is failing.
    Attempt to install the updates without performing the shutdown.
       --> Go to Control Panel - Windows Updates - Install any pending updates.

    Post your results from either route.

    The attached file shows the error, but I have no idea what it means, or what to do about it. Event.txt
    I changed the extension to allow it to be uploaded.

    Can you learn why the installation is failing?  Tell us.

    If you are still having the problem, see Option Two here
    I do not think Option One will help you.

    If you still have the problem, have you scanned for viruses, etc.?

    And if these are security related updates, you can get free support from Microsoft.

    Be sure to mention this is a Security issue.

    DoctorK12008--The log you have posted is not much use.  In Event Viewer, once you have found an error that is pertinent to this issue, double click on the word "Error".  Then click the button "Copy".  Paste into a word editor, like Notepad and post here.

    This: Please boot in Safe Mode. Then open C:\Windows\SoftwareDistribution. Select all the contents of the Windows distribution folder, and then delete them. Also remove the file C:\windows\winsxs\pending.xml. After doing that please restart the computer. Temporary disable the antivirus, and run Windows Update again.
