Windows Update offers updates for your OS as well as Microsoft products like Microsoft Office. An operating system is typically configured to download and then install Windows updates automatically if the device has an internet connection and new updates are available. These updates include critical ones that address vulnerabilities that lower protection against malware and viruses.

There are times, however, when Windows Update fails to work as expected and to install these updates. Our error code of focus is an example, where you are likely find an error message such as:

“There were some problem installing updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x800705b4).”

The 0x800705b4 error can be caused by several things, mainly by Windows system file damage. The system file error can be caused by an incomplete install or uninstall, or improper hardware or app deletion. The corrupted system file then leads to missing and misplaced information and files, which are necessary for the app or system to work fine.

Here are other factors involved:

  • OS failed to update on its own
  • Improper computer shutdown
  • Update service NOT configured as automatic update
  • Malware or virus attack
  • Registry error

Based on initial indications, the available Windows updates have been successfully downloaded but cannot be installed because there is a system distraction. Some have related the error to Office updates (2010 or 2013), which potentially aren’t installed or there are leftovers from the previous Office versions. There may also be a clash between the update and third-party anti-malware tool present in your computer.

Update Your System to Its Latest Version

Sometimes your computer fails to install updates automatically even when it’s designed to do so. This can be due to several reasons, including spotty internet connection. You can try to reinstall updates manually in order to solve error code 0x800705b4.

  1. Click Start > Control Panel.
  2. Choose System and Security > Windows Update.
  3. Hit Check for Updates found on the left side of the pane. Here you can update Windows to its latest version.

Updating Windows Defender (Windows 10/11)

If you are faced with this system error, try these steps:

  1. From the security center, update your version of Windows Defender. Look for it by clicking Start > Settings > Update & security > Windows Defender.
  2. Proceed to Windows Updates > Advanced options.
  3. Click the option for getting updates for other Microsoft products.
  4. Reboot your machine and check for updates next. Once you get the message “Your device is up to date,” hit Advanced options again. Next, recheck updates for Microsoft programs.

Restarting Windows Update

Follow the instructions below:

  1. Click the Windows + R keys.
  2. Type in services.msc. Hit Enter.
  3. Look for Windows Defender. If its status is not indicated (a blank column), right-click on it. Choose Start.
  4. If the force-start of Windows Defender yields an error, look for the Startup Type option and then set it to Automatic.
  5. Reboot your computer and run the update.

Running an SFC Scan

If you are still clueless as to how you can get rid of the error, try to run a System File Checker (SFC) scan for your system. This free tool can fix a number of system errors and enables you to locate corrupted system files for their prompt repair. Here are the steps:

  2. Right-click on the icon and select Run as administrator.

    • Windows Resource Protection could not perform the requested operation.
    • Windows Resource Protection found corrupt files and successfully repaired them.
    • Windows Resource Protection found corrupt files but was unable to fix some of them.

Running DISM

  3. On the left side, choose View All.

  1. Start your computer. Log on as an administrator.
  2. Click Start then choose All Programs > Accessories > System Tools.
  3. Next, click System Restore.
