\"How<\/a><\/figure>\n\n\n\n

Both Windows 11 and Windows 10 display an update error 0x800705b4 when a system update fails to install. If this error has occurred on your system and you can\u2019t install available updates, apply a few fixes and your issue should be resolved. We\u2019ll show you various ways to get around this problem on your computer.
<\/p>\n\n\n\n

A few reasons your software update fails to install are that your third-party antivirus or firewall is blocking the update, Windows Update is experiencing issues, your operating system files are corrupted, a third-party app is interfering, and more.\n<\/p>\n\n\n\n

Restart Your PC\n<\/span><\/h2>\n\n\n\n

One quick way to fix many minor system glitches is by rebooting your PC<\/a>. These glitches might be why your update isn\u2019t installing, and resolving these issues will fix your update problem.\n<\/p>\n\n\n\n

Make sure to save your unsaved work before turning off your computer.\n<\/p>\n\n\n\n

    \n
  1. Open the Start<\/span> menu using the Windows<\/span> key or by selecting the menu icon.
    <\/li>\n\n\n\n
  2. Select the Power<\/span> icon in the menu.
    <\/li>\n\n\n\n
  3. Choose Restart<\/span> to turn off and back on your computer.<\/li>\n<\/ol>\n\n\n
    \n
    \""Restart"<\/figure>\n<\/div>\n\n\n

    Turn Off Third-Party Antivirus and Firewall on Your PC\n<\/span><\/h2>\n\n\n\n

    If you\u2019ve installed a third-party antivirus or firewall on your PC, that program might be interfering with Windows Update, causing the feature not to install available updates. In this case, temporarily turn off the program to fix the issue.\n<\/p>\n\n\n\n

    You\u2019ll find the option to disable the antivirus<\/a> and the firewall on the main panel of the program. Then, try to install the available updates. You can turn the protection back on after installing the latest updates.\n<\/p>\n\n\n\n

    Note that you don\u2019t have to turn off your protection if you use Microsoft Defender Antivirus or Microsoft Defender Firewall. Both these items don\u2019t interfere with Windows Update.\n<\/p>\n\n\n\n

    Change How the Windows Update Service Starts\n<\/span><\/h2>\n\n\n\n

    The Windows operating system runs a background service called Windows Update to find and install the latest system updates. It\u2019s possible this service isn\u2019t running correctly<\/a>, causing your issue.\n<\/p>\n\n\n\n

    You can get around that by forcing the service to start automatically with a delay on your PC\u2019s boot.\n<\/p>\n\n\n\n

      \n
    1. Open the Start<\/span> menu, find Services<\/span>, and select the item with that name.
      <\/li>\n\n\n\n
    2. Find Windows Update<\/span>, right-click the service, and select Properties<\/span>.
      <\/li>\n\n\n\n
    3. Open the General<\/span> tab, select the Startup type<\/span> drop-down menu, and choose Automatic (Delayed Start)<\/span>.<\/li>\n<\/ol>\n\n\n

      1. Select Apply<\/span>, choose OK<\/span>, and close the Services<\/span> window.
        <\/li>\n\n\n\n
      2. Restart your PC and try to install the available updates.
        <\/li>\n<\/ol>\n\n\n\n

        Use the Windows Update Troubleshooter\n<\/span><\/h2>\n\n\n\n

        Microsoft has included a Windows Update troubleshooter in both Windows 11 and Windows 10 to allow users to find and fix various update problems<\/a>. Utilize this tool and let Windows help you resolve any update-related issues.\n<\/p>\n\n\n\n

        On Windows 11\n<\/span><\/h4>\n\n\n\n
          \n
        1. Open Settings<\/span> by pressing Windows<\/span> + I<\/span>.
          <\/li>\n\n\n\n
        2. Select System<\/span> in the left sidebar and Troubleshoot<\/span> on the right pane.
          <\/li>\n\n\n\n
        3. Choose Other troubleshooters<\/span>.

                Disable Other Updates When Updating Windows\n<\/span><\/h2>\n\n\n\n

                Windows updates other Microsoft products when you install system updates. It\u2019s possible one or more of these products are faulty, causing the main system updates not to install.\n<\/p>\n\n\n\n

                In this case, isolate those products\u2019 updates by turning off an option in Windows Update settings.\n<\/p>\n\n\n\n

                  \n
                1. Open the Start<\/span> menu, search for Windows Update settings<\/span>, and select the item with that name.
                  <\/li>\n\n\n\n
                2. Select Advanced options<\/span>.

                    Fix Windows\u2019 Corrupted System Files\n<\/span><\/h2>\n\n\n\n

                    Windows Update is a system feature and this feature relies on various core operating system files to function. If those core files are corrupted or damaged, the feature can stop working. This might be the case with your PC.\n<\/p>\n\n\n\n

                    Luckily, you can use a built-in tool called System File Checker (SFC)<\/a> to find and fix all the corrupted system files on your computer. This tool replaces the broken files with working files.\n<\/p>\n\n\n\n

                      \n
                    1. Open Start<\/span>, find Command Prompt<\/span>, and select Run as administrator<\/span>.

                        If a third-party app is interfering with Windows Update, clean boot your Windows PC<\/a> to isolate any third-party items from the operating system. You can install the available updates in this mode without any problems.\n<\/p>\n\n\n\n

                              If the Windows Update feature itself is experiencing problems, reset the feature\u2019s various components<\/a> to possibly fix your issue. You can use a reset script to reset the feature.\n<\/p>\n\n\n\n

                                  If nothing else works, your last resort is to manually download and install the available updates<\/a>. Microsoft has an online catalog where you can find and download the updates you want for your PC. This method helps you bypass the Windows Update feature\u2019s issues.\n<\/p>\n\n\n\n
