  • Windows Update code, error 8007007E

    I get a warning on my computer tells me that Windows cannot check the updates automatically. So I run windows update and it says that an error has occurred during the new updates for my computer. Then he said: code 8007007E windows has encountered an unknown error and.  Apparently because I bought my computer in February it has never been updated. I know this is a problem and I don't want my computer at risk. Help, please. I tried the troubleshooting, and it gives no help. I'm going crazy trying to figure it out.  I only am not computer savvy enough to keep the simple answers please :)

    Right-click on my computer and select properties: Windows version which is displayed on the general tab that results (for example, Windows Vista Ultimate Service Pack 2;) Windows 7 Ultimate 64-bit)?

    What application or antivirus security suite is installed and your current subscription?  What anti-spyware (other than Defender) applications?  What third-party firewall (if applicable)?

    A (another) Norton or McAfee application has already been installed on the computer (for example, a free trial version which is preinstalled when you bought it)?

    Hello

    What is the code exact error you get?

    Temporarily disable all security software and check if it helps.

    NOTE: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus
    software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet
    or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

    Also check the updates failed and see if there are error messages in Windows Update.

    1. open Windows Update.
    2. click view update history.

    You can also try to download and install the updates manually.

    Make sure that the following services are started:

    ·    Background Intelligent Transfer Service
    ·    Cryptographic services
    ·     Windows Update

    Follow these steps:

    1. go to start and type services.msc and press to enter.
    2. from the list of services, search for the above mentioned services and see if they are started and set to automatic.
    3. If they are arrested, then right-click on the service and select start to start the service.

    Desperately looking for advice on fixing my Windows Update; using Vista Home Premium, 64-bit. The problem has been consistent since about 10 days to have eliminated the possibility that it is related to the connection.  I completely many system restores.  I turned off Norton 360, even uninstalled and reinstalled.

    Thanks a lot for your help!

  • Problems installing Windows updates, code error 0x800736B1

    Hi all

    I am running Windows 7 and I am currently not able to install a bunch of Windows updates, obtaining the credits, "Code 800 b 0100: windows update encountered an unknown error."

    I tried all the suggestions on https://support.microsoft.com/en-us/kb/956702, none has helped.

    I ran Windows troubleshooting and got the error code: 0x800736B1.

    How can I fix? It seems that there is some random internet companies offering downloads that claim to solve the problem, but I don't know if one of them is trustworthy. I would rather solve this problem using products/patches from Microsoft.

    Any help would be greatly appreciated!

    I fixed recently updated, unless by a simple change of registration.

    Click Start > run Regedit as administrator > find HKLM\Components > rename the line that reads 'pendingrequired' D_word to "pendingrequired = 1".

    On some PCs, you won't find the HKLM\Components.  The registry entry will be under machine Hkey\local > components
