    I would just like to add, there are better options for PC protection other than Windows Defender. Malware can crush WinDefend fast. I would suggest KIS2016.

    Ken, if none of the suggestions in the post "Cannot start Windows Defender: Error 0x800705b4" have yet worked, then you may wish to do a refresh as this solved the problem for Ocman.

    Refresh Windows 10 - Windows 10 Forums

    Refreshing your PC fixes software problems by reinstalling the OS while preserving the user data, user accounts, and important settings. All other preinstalled customizations are restored to their factory state. In Windows 10, this feature no longer preserves user-acquired Windows apps.
