Microsoft update automatically installed the lastest definition update,
1.14.1948.9 for windows Defender (KB915597) both my machines running defender
report the following error on startup.

"Application failed to initialize: 0x800106ba. A problem caused Windows
Defender service to stop."

No other software has been installed, uninstalled or the setting adjusted on
either machine.

Pleaswe help.
 
Solved my own problem.

Looking at the Microsoft Defender site I noticed the expiry date on Beta2
was today. Downloaded and installed the final release and Defender now works
on both machines.

Thought I had already downloaded the final version, but obviously not.

A pop up message saying that the software had expired and that I need to
download the latest version would have been nice, rather than a cryptic error
message.

Having been similarly afflicted by the extremely irritating error message
from Microsoft Defender, I am very grateful to you for pointing me in the
right direction to resolve the problem.

The support email I received from Microsoft was little help in itself;
however, it did allow me to find your message. Why they couldn't have told
me that Defender had expired on 31st December and advise me that installing
the latest version would rectify the problem, is beyond me.

I am purely self-taught on a computer and it has been really hard work for
me to resolve this on my own. Many thanks for your help.
