Hi team,

I find following event logs in my event viewer. It's quite annoying though nothing abnormal happens. I wanna know the root cause and how to fix that.

Session "EventLog-Microsoft-Windows-MBAM-Diagnostic" stopped due to the following error: 0xC0000188

My box is 

Windows 8.1 64

I can provide more information if you need it.

Thanks,

Hi Britishdhez,

Thanks for your reply. But I am afraid that there is no ReadyBoost phases in my origin question. And the MBAM is Microsoft Bitlocker Administration and Monitoring. So it seems not related to ReadyBoost service. Any further thoughts then?

Thanks,

did you using bitlocker for your drive? or did you installed Microsoft BitLocker Administration and Monitoring?

did you try to disable bitlocker to test?

can you navigate to this option and disable MBAM and try to restart PC and check

Hi Britishdhez,

Sorry for the late reply. Yes. I've been using Bitlocker. However it's off for both two drives. And for now I don't think I can disable the Bitlocker. And for some unknown reasons, this error doesn't happen for ~1 week since the post. I still don't know why it appears and disappears unexpectedly. I would update this post if I come across it again in the future. Thanks again.
