I started getting this warning along with a yellow exclamation mark next to System Device > Intel Mgmt Engine Interface in Device Manager..
Here is the log entry from Event Viewer:
Log Name: Application

Description:
LMS cannot connect to Intel(R) MEI driver
Here is the info from Device Manager
This device cannot start. (Code 10)
An invalid parameter was passed to a service or function.
I had this problem before and was able to fix it by uninstalling MEI from Control Panel and then reinstalling. But it seems to be a recurring problem. this is a fresh installation using the built-in Windows Defender antivirus.
System Details:
Driver version: 9.5.10.1658
OS: Windows 8.1
Motherboard: Asus Z87-Pro
Processor: i7-4770K
Graphics: onboard intel 4600
Any suggestions would be appreciated.
