  • Try to update windows - (8007000D - has no error code) stops windows completely updated. Fixes for this error code?

    I tried to completely update of windows, but the 8007000D error code keeps causing the update fails. The update is for - Cumulative Update for Media Center for Windows Vista (KB982480). Could you be it someone please let me know if there are patches to get rid of this error, or get the update to pass by? Thank you!

    Hello

    You are able to install some other updates?

    I suggest you follow these methods and check.

    Method 1: Run the fixit.

    The problem with Microsoft Windows Update is not working:

    http://support.Microsoft.com/mats/windows_update/   

    Method 2: Run the clean boot and install the updates.

    To do this, follow the steps in this link:

    http://support.Microsoft.com/kb/929135

    NOTE: After you check the clean boot feature configure Windows to use a Normal startup using step 7 proposed in the above mentioned link.

    If the method above does not work, proceed to the next method.

    Method 3: download and install the Cumulative update for Media Center for Windows Vista (KB982480) from this link.

    http://www.Microsoft.com/en-US/Download/details.aspx?ID=6256

    If the method above does not work, proceed to the next method.

    Method 4: Rename the Software Distribution folder.

    Rename the temporary Windows Update Software Distribution folder. To do this, follow these steps:

    1. Open an administrative command prompt window.
    2. Run the following commands and press ENTER after each command:
      1. Net stop wuauserv
      2. CD %SystemRoot%\System32
      3. Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
      4. Net start wuauserv
    3. Try to install updates again.

    Important: When you use this method, the following problems occur:

    ·         Updates that are currently downloaded but which have not yet been installed must be downloaded again by using Windows Update or Microsoft Update.

    ·         When you remove the Software Distribution folder, your download history is deleted.

    ·         If you currently receive updates from Microsoft Update and Windows Update, you will need to reselect this option from the Windows Update Web site.

    Note If the problem is resolved and you can successfully download and install the updates, you can safely remove the SoftwareDistribution.old folder to recover disk space.

    I hope this helps!

  • Windows Update history IE8 installation failed (error code: 0x800706BE)

    original title: Windows Update History error code

    Historical Windows Update says my IE8 installation failed, but he did not. All updates installed after IE8 and Windows Update Custom says IE8 security there that more nothing to install. How can I fix the update history? The error code is 0x800706BE. I ran the tool FixIt from Microsoft Powershell and repaired Windows Update, but still false historical error. Windows XP SP3. I had rather not unintall/reinstall IE8.

    Then, assuming that IE8 is not offered again when run you a scan CUSTOM to http://windowsupdate.microsoft.com or automatic updates, you don't have to worry about this entry in the update history.

    Note: If you HAVE additional problems in IE8 or Windows Update (for example, when the next Cumulative Security Update for IE8 is released in April 2012, if not earlier), and I think that you will respond to this topic for further assistance (i.e. to bookmark this thread).

  • No sound, unable to update windows, a variety of error codes and dssenh.dll problems... Help?

    I'm running a Toshiba with Windows Vista. The 24th of this month, I have installed the updates for my computer, but when I rebooted I had absolutely no noise. I double checked to make sure it was not cut, I uninstalled and reinstalled the drivers, and then I tried to do a system restore. None of them worked.

    Then I tried to check updates more see if this would help to solve my current problem and began to find more mistakes, such as "could not find updates, error code: 800 b 0001 ' or 'Code error 8024402F' these are mistakes that I see most.

    Then when I go to open certain programs I get errors that say something about ' bad image: problem with Dssenh.dll "when I try to save it again, I get other errors with about 5 other .dll files.

    Of course, I went to the Microsoft website long enough... and I went through multiple options and steps, but nothing helped. So I thought that my last option is to ask.

    The last thing I can find is to download the "System update readiness Tool" to check for problems.

    Well, I can't download or run because of my error '800 b 0001'.

    I don't know what I would do at this point... Help?

    Before the update from the update began when my computer was being restarted... I had a black screen and had a weird three-step process that was supposed to be recommended. Meanwhile, there was a flood of information that crosses the screen.
    I ran a scan complete antivirus just in case, but it could be a virus that has not been detected?

    If anyone has any information, it is greatly appreciated... I don't know what to do.

    THANKS to anyone who can help!

    Hi julieWI,

    Please use the Forum of the community for Vista.

    When you say you tried manual installation, do you mean you went to MS and downloaded the update and tried to install it like that?

    If this isn't what you were doing, I recommend that download you and try this way.
