Once the scan is finished, check if the issue is resolved. If you were unable to run SFC scan before, or if the problem still persists, try running the SFC scan once again and check if that helps.


Solution 3 – Check your antivirus software

According to users, sometimes update error 0x800705b4 can appear due to your antivirus software. Having a good antivirus is important, but sometimes your antivirus can interfere with your system and cause this error to appear.

To fix the problem, you can try disabling certain antivirus features and check if that helps. If the issue is still there, you might want to try disabling your antivirus completely. In worst case scenario, you might have to completely uninstall your antivirus to solve this problem. Many users reported that McAfee Firewall caused this issue, so if you’re using it, be sure to disable it or delete it.

Even if you remove your antivirus, there’s no need to worry about your safety since Windows 10 comes with Windows Defender that acts as a default antivirus. If removing the antivirus solves the problem, it might be a good idea to consider switching to a new antivirus software.

There are many great antivirus tools on the market, but Bitdefender stands out from the rest with its features and high level of security. If you’re looking for a new antivirus, we strongly suggest that you consider this software.


Solution 4 – Make sure that Windows Defender service is running

In order to download updates, certain services need to be running on your PC. Speaking of services, users reported that update error 0x800705b4 can occur if Windows Defender service isn’t running, so be sure to enable it. To check if this service is running, you need to do the following:

  1. Press Windows Key + R and enter services.msc. Now press Enter or click OK.

To perform a soft restart, simply open the Start Menu and choose the Restart option. Once your PC restarts, check if the problem is still there.

Solution 8 – Perform clean install of Windows 10

As we already said, this error mostly occurs with users that upgraded to Windows 10 instead of performing a clean install. We know that is a presented option but, as you can see, it can cause a lot of issues. So, our advice is to perform a fresh install.

To do that, first you need to create an installation media using Media Creation Tool. After doing that, you need to do the following:

  1. Open the Start Menu, click the Power button, press and hold the Shift key and choose Restart.
