All I can say is it seems the interaction between Defender and any other Antivirus has changed. They both lived better together before this update.
In my case, there was a new version of ESET that did not show when checking for updates through the app, but was on the website. It cured my issues. Perhaps there is an update for whatever other app you might be using?
Two other things reset and now fixed:
1. Shortcut appended again to an app shortcut. I disabled that months ago, but this update rewrote the registry to the default.
2. Type commands in the RUN dialog were no longer remembered. I had set this a long time agao as well and the settings were changed buy this update.
Now, I had to update ESET to a new version just being rolled out. That created a new folder on MY IMAP server called Eset Antispam. It never asked and no settings for this. I have questions into ESET.
I got my first "pink" screen of death. Seriously. Undocked and restarted on batter and right after the Lenovo splash screen got the PSOD pagefault in NSKERNEL if I recall. Hoping this was a fluke. I have the memory dump
One more unexplored error 18 in Bluetooth I will research. New and happens on very boot now.
Ahhh, everything was working so well...
