    <\/p>\n\n\n

    Starting App Readiness Service<\/h3>\n\n\n

    Sometimes, the App Readiness service is disabled<\/a>, which can interfere with updates and cause the error 0x800705b9. Let\u2019s ensure it\u2019s running:<\/p>\n\n\n\n

      \n
    1. Open the Services<\/strong> application by typing “services” in the Windows search bar.<\/li>\n\n\n\n
    2. Locate App Readiness<\/strong> in the list.<\/li>\n\n\n\n
    3. Double-click it, set the Startup type<\/strong> to Automatic<\/strong>, and click Apply<\/strong>.<\/li>\n\n\n\n
    4. If the Start<\/strong> button is clickable, press it and click OK<\/strong>.<\/li>\n<\/ol>\n\n\n\n

      If this doesn\u2019t resolve the error, don\u2019t worry; let\u2019s try the next step.<\/p>\n\n\n\n

      <\/p>\n\n\n

      Moving the $WinREAgent Folder<\/h3>\n\n\n

      The 0x800705b9 error code can sometimes happen when the $WinREAgent folder might contain corrupted files. Here\u2019s how you can address it:<\/p>\n\n\n\n

        \n
      1. Open File Explorer<\/strong> and navigate to the C drive. (C:\\)<\/li>\n\n\n\n
      2. Enable hidden items via View<\/strong> > Show<\/strong> > Hidden items<\/strong>.<\/li>\n<\/ol>\n\n\n\n
        \n
        \"Moving<\/a><\/figure>\n<\/figure>\n\n\n\n
          \n
        1. Locate the $WinREAgent<\/strong> folder (if it exists).<\/li>\n\n\n\n
        2. Copy the folder to your desktop for backup.<\/li>\n\n\n\n
        3. Delete the original folder from the C:\\ drive.<\/li>\n<\/ol>\n\n\n\n
          \n

          Is it safe to delete the $WinREAgent folder?<\/strong>
          Yes, you can safely delete the $WinReAgent folder created during Windows updates.
          Reference:           https:\/\/www.easeus.com\/knowledge-center\/what-is-winreagent-folder.html<\/a><\/p>\n<\/blockquote>\n\n\n\n

          If the error persists, let\u2019s continue troubleshooting by running the inbuilt Windows Update troubleshooter<\/a>.<\/p>\n\n\n\n

          <\/p>\n\n\n

          Running Update Troubleshooter<\/h3>\n\n\n

          Windows has a built-in troubleshooter that can automatically detect and fix update issues:<\/p>\n\n\n\n

            \n
          1. Go to Settings<\/strong> > System<\/strong> > Troubleshoot<\/strong> > Other troubleshooters<\/strong>.<\/li>\n\n\n\n
          2. Locate Windows Update<\/strong> and click Run<\/strong>.<\/li>\n\n\n\n
          3. Follow on-screen instructions and restart your computer if needed.<\/li>\n<\/ol>\n\n\n\n
            \n
            \"Windows<\/a><\/figure>\n<\/figure>\n\n\n\n

            Did this step help? If not, let\u2019s move on. \ud83d\ude09<\/p>\n\n\n\n

            <\/p>\n\n\n

            Restart Windows Update and Background Intelligent Transfer Service<\/h3>\n\n\n

            Restarting these services can often resolve update problems. Here\u2019s how:<\/p>\n\n\n\n

              \n
            1. Open Services<\/strong> again. (As we did in the first step: Starting App Readiness Service.)<\/li>\n\n\n\n
            2. Locate Windows Update<\/strong> and set its Startup type<\/strong> to Automatic<\/strong>. Click Apply<\/strong>, then Start<\/strong> if available.<\/li>\n<\/ol>\n\n\n\n
              \n
              \"Locate<\/a><\/figure>\n<\/figure>\n\n\n\n
                \n
              1. Repeat the steps for Background Intelligent Transfer Service<\/strong> (BITS).<\/li>\n<\/ol>\n\n\n\n
                \n
                \"Locate<\/a><\/figure>\n<\/figure>\n\n\n\n

                If the issue still lingers, don\u2019t give up yet; there are more solutions to try.<\/p>\n\n\n\n

                <\/p>\n\n\n

                Run Windows 11 Installation Assistant<\/h3>\n\n\n

                When built-in update methods fail, the Windows 11 Installation Assistant can help:<\/p>\n\n\n\n

                  \n
                1. Visit the Windows 11 Installation Assistant<\/a>.<\/li>\n\n\n\n
                2. Download and run the tool.<\/li>\n\n\n\n
                3. Follow the on-screen instructions to update your system.<\/li>\n<\/ol>\n\n\n\n
                  \n
                  \"Try<\/a><\/figure>\n<\/figure>\n\n\n\n

                  If this method isn’t helpful, check the Microsoft Update Catalog.<\/p>\n\n\n\n

                  <\/p>\n\n\n

                  Checking Microsoft Update Catalog<\/h3>\n\n\n

                  This method allows you to manually install the problematic update:<\/p>\n\n\n\n

                    \n
                  1. Open the Microsoft Update Catalog<\/a>.<\/li>\n\n\n\n
                  2. Search for the update using its KB number.<\/li>\n\n\n\n
                  3. Download the appropriate version (e.g., x64, x86) and manually install it.<\/li>\n<\/ol>\n\n\n\n
                    \n
                    \"Search<\/a><\/figure>\n<\/figure>\n\n\n\n

                    If this doesn\u2019t work, try resetting Windows Update components!<\/p>\n\n\n\n

                    <\/p>\n\n\n

                    Resetting Windows Update Components<\/h3>\n\n\n

                    Sometimes, resetting update components is necessary to fix error code 0x800705b9. Let\u2019s automate this process:<\/p>\n\n\n\n

                      \n
                    1. Open Notepad<\/strong> and paste the following commands:<\/li>\n<\/ol>\n\n\n\n

                        \n
                      1. Save the file as Wufix.bat<\/strong>.<\/li>\n\n\n\n
                      2. Right-click the file and select Run as Administrator<\/strong>.<\/li>\n\n\n\n
                      3. Wait for the process to complete, then restart your PC.<\/li>\n<\/ol>\n\n\n\n

                        If this still doesn\u2019t solve the issue, we\u2019ve got one more approach to try.<\/p>\n\n\n\n
                        <\/p>\n\n\n
                        Updating via Media Creation Tool<\/h3>\n\n\n
                        This is the last step and often the most effective:<\/p>\n\n\n\n
                          \n
                        1. Download the Media Creation Tool<\/a> from Windows official site.<\/li>\n\n\n\n
                        2. Run the tool, select Create installation media<\/strong>, and save the ISO file.<\/li>\n\n\n\n
                        3. Mount the ISO and run setup.exe<\/strong>.<\/li>\n\n\n\n
                        4. Follow the prompts to update your system while keeping your files and apps.<\/li>\n<\/ol>\n\n\n\n
                          By now, your issue should be resolved. If it isn\u2019t, you may want to contact Microsoft Support for further assistance.<\/p>\n\n\n\n
