Error 0x800705b4 in Windows Update and Windows Defender


The Windows Update Error 0x800705b4 is a typical problem that happens when people try to upgrade or update their Windows versions to newer versions. In 2016, Microsoft released an update to its Windows 10 operating system. This version was dubbed the “Windows Anniversary Update” and was expected to reach around 350 million devices around the world at the time.

It was first assumed to be a great launch, but it turned out to be a bit of a flop when consumers starting experiencing a slew of download-related issues. It included the 0x800705b4 Windows Update Error. The error was aggravating since it caused the download to stall or become stuck halfway through, lasted for extended periods of time, prevented any further updates from taking place, and caused a slew of other issues when users tried to use it while it was being downloaded.


Other outdated/corrupted components that are the major cause of the 0x800705b4 problem are related to the Windows Defender System’s functionality when it does not allow or is unable to start. Defender Systems that were out of current were unable to process the update and so prevented it from being implemented. Configurations and third-party software were also an issue when the update was being installed.
