Think Defender is buggy.
Only other malfunction have had was shut down did not work, it kept reopening so had to pull the plug, restarted, messed about with power options, this seemed to settle it after switching different settings before reverting to default...reported it.
The definitions for the failures

Temp fix:
Delete following registry key:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MpSigStub
Run update again.
Making temporary fix's does not stop the problem in the first place.
Need to find out what the root cause is .

Peculiar how systems differ as my 15063.11 WD updates have never faltered.
WD updated this morning normally after registry fix that Vincentwindows suggested and posted. (Post #75)
Thanks Vencent and welcome to TF, started with a bang.
