mysqld won't start on Windows 10

[CE Stanley]

I am new to MySQL and am having problems getting mysqld to remain running on a newly imaged Windows 10 PC. mysqld starts and shows in Task Manager but stops very soon after it starts. My error log is mostly empty an contains no errors, just Notes:

Anyone have any ideas what is going on? Why mysqld stops after starting? I am specifing error_log_verbosity=3 to get this information. Is there some command line option to get more information or get information from innoDB and why it is shutting down?
