DefenderApiLogger Error after Fall Up date

no1yak · 20 Oct 2017

I have two machines, one was up-dated via windows up-date the other I did a clean install. Both machines have this error.
every time they boot up. Anyone know what is causing it or better still a fix.

Start - Run - perfmon - Data Collector Sets - Startup Event Trace Sessions

Open Defenderapilogger - Stop Condition - Increase Maximum Size (or uncheck it to make it unlimited)

Thanks for the info, I have now increased the Max Size. I noticed that you have that Api logger disabled.

I have got all logging disabled, except UBPM, which runs regardless and Security required by UAC.
I see no point of having hundreds of events logged per second, which I would never read anyway.
Disabling Windows Event Log service has increased the speed of installations enormously. :)

I know this is old but the same problem has now popped up after the new update but I get access denied when I try to make any changes to the DefenderApiLogger; anyone to how to fix it now, thanks.
