I found the error, it's the service Windows Event Log by Microsoft.
I opened msconfig.exe --> services tab and first de-activated all non-Microsoft services and rebooted, error still happened.
Then I did the opposite, deactivated all Microsoft services (no error), and then I activated them in bulk of 5 services, when I found the block of 5 services that caused the error, I activated all services except those 5, did a reboot, no error. After that I activated one after the next service until I had the one deactivated that caused the error.
Now my next question is, how important is the Windows Event Log Services. Should I fix the error and try to reinstall Windows Event Log (if so how?) or can I leave it deactivated?
