For weeks now keep getting the message:

"Definition Update for Windows Defender - KB2267602 (Definition 1.213.5087.0) - Error 0x80070643"

While the computer seems to run ok, in the mean time I cannot update windows 10...

    The fix that worked for me was to install Avast (free version) and then uninstall Avast. Windows Defender update errors stopped. Why?

    Thanks for the feedback, André Kennedy. This really isn’t a Windows Update issue, as the OP quickly discovered. It’s just a case where Windows Defender doesn't get switched off in the registry when the third-party AV app is installed. So you have to either reinstall the third-party app; use the shortcut method that I’ve described above; or turn Defender off in Group Policy. People with the Home edition of Windows 10 can just download and run the Turn_Off_Windows_Defender.reg  file to disable Windows Defender in the Group Policy registry key:
