I run Windows 10 64bit and Norton Security Premium, which disables Windows Defender. For weeks now Windows Update downloads and 75% installs an update for Windows Defender, for the result, see attachment. I have searched Microsoft for hours but can find no answer to this. I have run the Windows Update Troubleshooter and it displays ‘Service registration is missing or corrupt’, I have disabled Norton Firewall and Autoprotect before trying the update, nothing works. Anybody else have this problem?

Peter
