Nearly 8 years later, encountering this problem too. Windows 10 Pro, v1909
We are required to have this Windows security policy enabled (see Windows' gpedit.msc):
Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Audit Policy -> Audit Privilege use = "Success, Failure"
This causes event ID 4673 to be logged in the Windows event log system, failing while trying to use "SeTcbPrivilege". In my case there are nearly 30 of these events logged per second!!
The offending application is our VC++ 10 executable, which uses the Phidgets21 library, release date 2019-11-06. Currently don't have the Phidgets21 control panel or web service installed, just using the windevel package, running as an Admin user, but without elevated rights.
